Tim Wheeler of Burt, left, and Todd Thorp of Saginaw display their electro-magnetic motor that they say has virtually unlimited applications. Wheeler says the motor could be scaled up to power everything from automobiles to appliances, running for up a year without being plugged in.

Tim Wheeler seems to have done the impossible, inventing an electromagnetic engine that runs almost on its own.

He showed off a prototype of the "EME," for Electro Magnetic Energy, on Wednesday in Bay City.

"It does a lot more than what I'm showing you or telling you," said Wheeler, a 43-year-old "jack of all trades" from Burt near Birch Run.

His small, patented motor sips power from six motorcycle batteries while also recharging them. It works by using positive and negative charges to push and pull magnets mounted to a shaft inside a plastic case. There's a recovery system that prolongs the battery life.

Wheeler says the EME could be scaled up to power everything from automobiles to appliances, running for up a year without being plugged in.

He and others involved with TWM Technology in Bay City are looking for investors or government funding to continue their research.

So far, they say they've sunk three years and more than $50,000 into a large version of the EME installed into a 1951 Ford pickup.

That big engine runs, using the same six batteries, but needs work, because it was built with metal parts. A key to the EME is using plastic so as not to interfere with the magnets, said TWM President Todd Thorp, a Bay City native who now lives in Saginaw.

"I want to put it into actual production," Wheeler said of his invention, and eliminate all or most of the use of gasoline in America.

The hope is to license the technology and have another company make the motors.

For now, Wheeler said he makes a living hauling scrap, fixing cars and doing other odd jobs.

He says he was "raised in a scrapyard" and came to understand electricity at a young age.

"We use the full effect of the magnetic field, unlike any other motor," he said.

The prototype EME has been shown to be up to 82 percent efficient, he said. Wheeler said he's run the little motor for an hour and only used 2 percent of the battery power.

Wheeler started working on the motor "out of curiosity."

The prototype was made by hand, in his garage, with about $100 worth of parts. He thinks larger versions could be built and sold for less than gas-powered engines.

The prototype could be used to move a moped at speeds of up to 50 mph, said Henry Johnson, a Bay City real estate broker that hosted Wednesday's showing.

Johnson is part of Angel Marketing in Burt, which is trying to promote the EME. The group also includes T.J. Swihart of Bay City, a retired scientist from Dow Corning Corp.

So far, Johnson said he's contacted General Motors, Ford and Chrysler officials about the EME, but they haven't been willing to talk to him - yet.

Wheeler's next goal is to rebuild the large motor and show it off on the roads of Michigan.

Thorp, a former small business owner, said he's committed to the EME partially because of his 4-year-old son, Zackary.

Unlike gas engines, which pollute the environment, the EME runs clean, without as much as a tailpipe, he said.

"Air quality for the future," Thorp said of his motivation. "Not just for him, but for everyone."

Johnson said potential investors can call him at 684-7050.

TWM Technology's Electro Magnetic Energy (EME) sips power from six motorcycle batteries while also recharging them.

The present prototype EME has been shown to be up to 82 percent efficient. It is capable of tremendous speed. One of the prototypes has achieved 10,000 rpm. They expect that a more robust, optimized prototype could possibly handle up to 20-25,000 rpm.

When the motor runs above a certain speed, the shaft rides on a magnetic cushion, not on bearings, eliminating the metal-on-metal wear all together.

The motor produces no heat but runs at ambient temperature, so super-cheap, recycled materials could be used in its manufacturing.

The company expects that the motor could be scaled to power everything from cell phones to air craft carriers.

They expect their next prototype (completion expected by end of Jan. 2009) could be over 100% efficient, harnessing permanent magnet power which may be drawing it from some kind of universal energy source that nature provides inexhuastibly and for free.

Allegedly, not only does TWM Technology, LLC's motor produces enough electricity to keep its batteries topped off, with energy left over for other use, but it also produces torque. The motor does not heat up under load, so it can be built from cheaper materials, including wood and plastic.

Figure 1 from the TWM patent application US20080143206.  

Johnson says their new design simplifies this by using plastic components.

Animation by Kevn Lambson of PES Network, Inc..  

TWM says this is an accurate depiction.

TWM's 15 x 30-inch motor prototype is expected to produce 600 HP and 5,000 VAC -- enough to power a pickup truck.

Henry Johnson, Marketing Director for TWM Technology, LLC, contacted me on Sept. 7 to inform me that one of their electric motor patents had been awarded that same day.

The patent describes the layout of the motor, but it doesn't say that with this layout the motor is allegedly able to run from a battery, keep that battery charged, and produce excess energy for use -- harvesting electrical energy from the environment somehow in the process.  It's like a solar array, harvesting energy from nature, except that the source of power doesn't rise and set each day, nor is it obstructed by clouds, dust or bird droppings.  Put simply, it is claimed (not in the patent) to be a self-looped system with energy left over for use.  The excess comes from nature through the set-up.

The awarded patent confirms that the design is unique.

Imagine a motor that could power a pickup truck without stopping for fuel; and the motor is just as powerful but just 1/3 the size of the regular engine.  That is the prototype they are presently working on, and think they might have worked out soon.

Meanwhile, Johnson says they do have other prototypes that can be seen and demonstrated that exhibit the overunity effect -- more power out than is put in.  One prototype is made of wood rather than metal and spins at 15,000 rpm.  Another prototype puts out 1/3 of a horsepower, and runs up to 10,000 rpms.  He said the "prototype motor works beautifully."

They have had a hard time getting support from mainstream scientists because the claim goes against conventional "laws of physics" as to what is and is not possible.  "The one one who really understands what we're doing is Tom Bearden," said Johnson.  I was in on a three-way conference call with Bearden last year in which he described why TWM was able to do what they are doing.  It was amazing.

The way Johnson describes it is that "the process magnifies the magnetic energy of a permanent magnets."  Put simplistically, as two magnets in the rotor pass by five electromagnets in the stator with alternating polarities, there are 20 compressions in each rotation because both sides of the magnet are being used, and there are two magnets in the rotor.  Johnson explains that when the motor spins at 4,000 rpms the permanent magnets are being pulsed ("magnified") 70 times per second.  Secondary windings in each coil of the electromagnet pick up back EMF and dump it into a capacitor to recharge the battery.  And not only do the permanent magnets not deplete, but the "compression" effect actually tends to strengthen the magnets.  Furthermore, the faster the motor spins, the less current it draws proportionately.  And it doesn't produce heat due to its efficiency, even under heavy load, so it could be manufactured from cheaper materials including plastic and wood.  The motor has a lot of torque.

"We've figured out how to make magnets the fuel", says Todd Thorpe, TWM President.

As of the writing of this story, the USPTO patent database is current to Sept. 7, but apparently doesn't include the TWM patent yet.

You can view the patent application titled simply "Electric motor", with lead inventor, Kenny L. Wheeler, filed on Aug. 13, 2007.

Back in 2008 TWM claimed to have run a moped for 8 miles in a gymnasium, leaving the batteries with the same charge they started out with.  The combined weight of the moped and rider was about 350 pounds.

Johnson says that they are "very close" to being to the point where they can commercialize this technology.  He welcomed our New Energy Congress to arrange to do a validation of their technology.  As mentioned in our last story, we are presently seeking a grant to finance such validations, as they are not cheap to execute.

BACKGROUND OF THE INVENTION

This application claims the benefit of priority to U.S. Provisional Patent Application Ser. No. 60/875,654 filed Dec. 19, 2006. The instant invention relates to a permanent magnet electric motor. Permanent magnet electric motors are well known in the art and are available in many unique variations. The commutator system of a permanent magnet electric motor can be replaced by a position sensor/solid state switch system to produce the well known “brushless” motor. U.S. Pat. No. 6,849,984 discloses a permanent magnet electric motor having permanent magnets mounted in a rotor and electromagnets positioned adjacent the face of the rotor.

Despite the significant improvements that have been made in the field of electric motors, there remains a need for additional improvements to such motors.

DETAILED DESCRIPTION

Referring now to FIG. 1, therein is shown an exploded view of a portion of an electric motor embodiment of the instant invention laid out along the longitudinal axis of a shaft (shown in FIG. 8). Shaft bearing mounts 1 are used to support shaft bearings 9. Rotor adapters 2 are attached to the rotors 3. Rotors 3 are preferably made of a nonmagnetic material such as glass fiber reinforced polycarbonate polymer. Permanent magnets 5 are mounted in the rotors 3 and held in place by magnet caps 4. Splined attachment hubs 6 are attached to rotors 3 for receiving a splined portion of the shaft. Shaft bearing retainer plates 7 and gaskets 8 are used to retain the bearings 9 in position. Shaft oil seals 10 retains lubricant in bearings 9. Electromagnets 12 (only the iron core of the electromagnets is shown and not the winding of copper magnet wire around the core, the winding being potted in a thermoset polymer) are mounted in stators 11 and retained by electromagnet caps 13. Shaft bearing mounts 1 are attached to main housing retainer rails 14. The north south orientation of the permanent magnets 5 are all the same and are about parallel with the longitudinal axis of the shaft. The north south axis of the permanent magnets of the outer rotors are spaced rotationally from the north south axis of the permanent magnets of the central rotor. The electromagnets 12 are located in the stator so that when the electromagnets are energized the north south axis of the electromagnets 12 are about parallel with the longitudinal axis of the shaft. A shaft rotation position sensor (described in detail below) is positioned to sense the rotation position of the shaft so that specific electromagnets 12 can be energized by way of the an electric switch at a rotation position of the shaft when specific permanent magnets 5 are near the energized electromagnets 12 to cause the shaft to rotate.

Referring now to FIG. 2, therein is shown an exploded view of a commutator and slip ring portion of the electric motor embodiment of FIG. 1 including commutator retainer 17 which is attached at end of the shaft of the motor by way of a set screw. Positive copper commutator/slip ring 22 engages with first plastic insulator spacer ring 21, over plastic insulator tube 20, over copper negative commutator/slip ring 19 which engages with second plastic insulator spacer ring 18, the whole assembly being attached to the retainer 17. Five brushes (not shown in FIG. 2 but shown as elements 23, 24, 25, 26 and 27 in FIG. 3) are arranged in a symmetric manner radially of and in contact with the commutator while two brushes (not shown in FIG. 2 but shown as elements 19a and 22a in FIG. 3) are in contact with the extended cylindrical slip ring portions of the negative and positive commutator portions 19 and 22.

Referring now to FIG. 3, therein is shown a schematic view of a power transistor switching circuit of the electric motor embodiment of the instant invention of FIGS. 1 and 2. The power transistor switching circuit includes: NPN power transistors 43, 44, 45, 46, 47 and 48; PNP power transistors 38, 39, 40, 41, 42 and 49; electromagnet coils 28, 29, 30, 31, 32, 33, 34, 35, 36 and 37; a dual 500,000 ohm potentiometer 54; switches 52 and 53; 1,000 ohm resistors 50 and 51; and batteries 55 and 56. The use of the transistor switching circuit significantly reduces the current carried by the brushes. However, it should be understood that a transistor (or other solid state) switching system is not required in the instant invention. Furthermore, the shaft rotation position sensing means is not limited to a commutator but can be any suitable means such as a hall effect sensor or an optical system. Thus, the motor of the instant invention can be of the “brushless” type or the brush type or a hybrid system.

Referring again to FIG. 1, preferably the one north south end of the core of the electromagnets 12 is larger than the other north south end of the core of the electromagnet with the larger ends facing the central rotor. The degree of rotational off-set of the permanent magnets of the central rotor relative to the permanent magnets of the outer rotors is preferably such that when the north south axis of the permanent magnets of the outer rotors are aligned with the north south axis of an aligned pair of energized electromagnets in the stator, the north south axis of the permanent magnet in the central rotor is aligned with the edge of the cores of said electromagnets. Most preferably, the core of the electromagnets at their cross-sectioned mid-section is a rectangle twice as deep as it is wide while the enlarged end of the cores is a square as shown in detail in FIG. 10.

It should be understood that the motor of the instant invention can be operated in unipolar or bipolar manner. It should be understood that the motor of the instant invention can be used as an electrical generator when the shaft thereof is driven. The motor of the instant invention can even be operated as both a motor and a generator at the same time by positioning a pick-up coil(s) near the rotor or by using a portion of the electromagnets as a pick-up coil(s). It should be understood that although FIG. 1 shows five electromagnets mounted in each stator, any number of electromagnets (that fit in relation to the permanent magnets) can be used in a stator the instant invention. Preferably, an odd number (such as 3, 5, 7 or 9) of electromagnets are used in each stator of the instant invention.

Referring now to FIG. 4, therein is shown a schematic view of the interaction of the permanent magnets 5 and electromagnets 12 of the embodiment shown in FIG. 1 as one set of the permanent magnets 5 rotate toward one set of the energized electromagnets 12 in the direction shown by the arrows in response to the attraction between the permanent magnets 5 and the energized electromagnets 12.

Referring now to FIG. 5, therein is shown a schematic view of the interaction of the permanent magnets 5 and electromagnets 12 of the embodiment shown in FIG. 4 as the permanent magnets 5 rotate further toward the energized electromagnets 12 in the direction shown by the arrows in response to the attraction between the permanent magnets 5 and the energized electromagnets 12.

Referring now to FIG. 6, therein is shown a schematic view of the interaction of the permanent magnets 5 and electromagnets 12 of the embodiment shown in FIG. 5 as the permanent magnets 5 rotate away from the reverse energized electromagnets 12 in the direction shown by the arrows in response to the repulsion between the permanent magnets 5 and the reverse energized electromagnets 12.

Referring now to FIG. 7, therein is shown a schematic view of the interaction of the permanent magnets 5 and electromagnets 12 of the embodiment shown in FIG. 6 as the permanent magnets 5 rotate away from the non-energized electromagnets 12 in the direction shown by the arrows.

The embodiment depicted in FIGS. 4-7 is an example of the bipolar operation of the motor of FIG. 1. If the electromagnets 12 in FIGS. 4-7 were not reverse energized (and non-energized in FIGS. 6 and 7), then the motor of FIG. 1 would have been operated in a unipolar “pull only” manner. And, if the electromagnets 12 in FIGS. 4-7 were only reverse energized (and non-energized in FIGS. 4 and 5), then the motor of FIG. 1 would also have been operated in a unipolar “push only” manner. FIGS. 4-7 show only one set of the five sets of electromagnets of the motor of FIG. 1 and only one set of the opposed sets of permanent magnets. The commutator and slip ring system shown in FIGS. 2 and 3 provides the rotation position sensing and switching for all sets of the electromagnets relative to all sets of the permanent magnets of the motor.

Referring now to FIG. 8, therein is shown a side view of the shaft 100 to be used with the motor of FIG. 1. The shaft 100 has a central splined portion 103 as well as splined portions 102 positioned near the ends of the shaft 100. The shaft 100 also has threaded portions 101 positiond near the ends of the shaft 100. Referring now to FIG. 9, therein is shown a detailed side perspective view in full of one of the permanent magnets 110 to be used in the motor of FIG. 1. The permanent magnet 110 is a three inch diameter neodynimun type that has a retaining groove 111. The retaining groove 111 engages a ridge machined in the rotors and magnet caps the of the motor. Referring now to FIG. 10, therein is shown an enlarged view of one of the electromagnet cores 120 to be used with the motor of FIG. 1. The core 120 is made of 48 layers of 1/16 inch thick iron layers 121. One end of the core 120 has a square shape three inches on a side. The other end of the core 120 has a rectangle shape three inches by one and one half inches. The edges of the core 120 are rounded with a radius of about 1/32 inch. The core 120 is wound with 12 gauge copper magnet wire potted in thermoset resin.

The electromagnet(s) of the instant invention can be cooled to increase the maximum sustained power of the motor of the instant invention. For example, a motor of the instant invention used to propel a vehicle such as an automobile can be cooled by the air conditioning system of the automobile. Preferably such cooling is sufficient to cause the electromagnet(s) to become a superconducting electromagnet(s).

It should be understood that the motor of the instant invention can be modified to run on alternating current by connecting the electromagnet(s) to alternating current and eliminating the shaft rotation position sensor and an electric switch. Such modified motor is hereby included within the broad scope of the instant invention. Such modified motor has a speed dependent on the frequency of the alternating current. Of course, such modified motor preferably has additional permanent magnets mounted in the rotors in the same manner as the original permanent magnets since all of the electromagnets are being energized at the same time by the alternating current. Furthermore, it should be understood that it is equivalent in the instant invention to mount the permanent magnets in a stator(s) while the electromagnets are mounted in the rotor(s). However, such an arrangement requires slip rings and brushes to energize the electromagnets and thus such an arrangement is not preferred.

Conclusion

While the instant invention has been described above according to its preferred embodiments, it can be modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the instant invention using the general principles disclosed herein. Further, the instant application is intended to cover such departures from the present disclosure as come within the known or customary practice in the art to which this invention pertains and which fall within the limits of the following claims
