General Description

The invention may be broadly said to be, an electric motor and/or generator comprising a rotor consisting of a number of radially arrayed permanently magnetised poles, and a sta-tor consisting of a number of radially arrayed permanently magnetised poles, together with a number of wound poles.

The rotor's permanently magnetised poles use ferrite magnetic cores, and may comprise any even number of poles. The stator's wound poles employ steel or iron cores.

The device is essentially a D.C. machine, but may be fed A.C. input with the use of a solid state converter.

The Rotor uses a number of similar polarity permanent magnetic poles, i.e., all-South or all-North.

A further set of wound poles arc radially arrayed in the stator, and are arranged in such a manner as to be fed energy, that is excited by back E.M.F. energy, from the poles of the rotor. Associated circuitry is provided to feed the energy back to the drive poles of the motor.

The resulting characteristics of this design is that once the rotor is moved from the position of equilibrium, each pole is attracted to, or repulsed by the stator poles, but at a precise geometrical point with respect to them, the input current to the drive coils ceases.

As a result, the collapsing field current is in the opposite direction to the applied force, thus reversing the magnetic polarity of the stator coils. This forces the rotor poles away (reaction), which is the instantaneous response of a system to an applied force, and is manifested as the exertion of a force equal in magnitude, but opposite in direction to the applied force.

Pulsing the D.C. input current, overcomes losses generated in conventional motors. According to classical electrical engineering theory, efficiency is greater the more nearly equal the Back E.M.F. (electromotive force) is to the applied voltage, i.e. the lower the input current. Figure 6 shows that there is minimum 100% back E.M.F. relative to the supply source of input D.C. voltage (according to classical electrical theory), which virtually depicts a sine wave due to the effect of the collapsing field.

This effect also overcomes the electrodynamic torque problems associated with conventional motor designs. (As input power varies with the duty cycle pulse; i.e. the lower the input current, the lower the input current, and the lower the speed, the greater the torque.) At clip-off, the back-EMF ceases, the collapsing field takes over, opposing the outgoing rotor magnet and thus increasing momentum.

With this design force is applied twice during each D.C. pulse, with pulse-on, and with pulse-off.

The timing of the pulses are determined by the dimensions of the motor itself, i.e. the speed of rotation of the motor's central axle, the position of the rotor magnets in relation to the stator windings, as well as the distance that the rotor magnets travel when passing across the poles of the stator winding (See accompanying diagrams). CONSTRUCTION AND OPERATIONAL NOTES Important Factors

1) Care must be exercised when assembling and wiring the drive windings to make sure that their polarities match the rotor magnet polarity.

2) Common earthing must be avoided in order to preclude voltage and /or current loops. (If a number of drive windings do need to be commoned, use very low resistance conductors and employ a transmission type earthing system only.)

Stator (Drive) winding resistances are your choice. Robert Adams' machines were built varying from 0.03125 to 27 ohms per set. He has experimented with two, four, and eight pole machines. Efficiency increases with the number of wound poles in the stator.

Motor generators with a single, two, or three phase can be built to this design. A number of rotors may be ganged together on the same shaft in order to increase power output and does not require the use of any commutator, brushes or slip rings, all of which contribute to energy losses in ordinary motor generators.

Unlike conventional Series D.C. machines, this motor can be off-loaded, finds it5 own speed, and will run at that speed indefinitely. A conventional DC motor will run itself to destruction with off-loading. It requires no cooling, nor any overload protection, even if short circuited.

A number of highly qualified individuals have seen these devices running and producing energy at well above 100% efficiency. Let's hope that some of you can achieve similar results.
