Abstract: An apparatus for transferring torque magnetically with a primary rotary member and a secondary rotary member. The primary rotary member has permanent magnets, the secondary rotary member with electro-conductive materials. The secondary rotary member also having magnetically permeable material. The secondary rotary member is placed partially or totally inside the primary rotating member. This causes the two rotary members to axially overlap one another more or less as desired. Rotation of the primary rotary member causes rotation of the secondary rotary member, since magnetic flux lines emanating from the permanent magnets mounted on the primary rotating member, cut through all, or part of, the electro-conductive material placed on the secondary rotary member. This can vary the torque transmitted between the two rotary members, thereby enabling the varying of the rotational speed of the secondary rotary member relative to the primary rotary member.

The timing of the oscillation and pausing of the outer rotor may be controlled by EPROM circuitry and a timing sensor mounted on the output shaft or gear.

Abstract: The present invention discloses a generator (1) able to generate either unidirectional current or bi-directional current. A rotatable disc (7) has a conductive track (9) and a ferromagnetic bridge (8). Brushes (12, 13) switchingly open circuit a coil (16) or connect the coil (16) to a load resistor (R). Movement of the disc (7) results in bridge (8) shunting a core (15) of the coil (16). This generates an emf in the coil (16). If the circuit is closed, current flows in the resistor (R). If the circuit is open, no current flows. The arrangement is such that current only flows when the bridge (8) approaches the magnet (14)—not when the bridge (8) recedes from the magnet (14). Thus, only the magnetic attraction for the bridge (8) by the magnet (14) impedes the movement of the disc (7) as the bridge (8) recedes from the magnet (14) without the disc's movement also being impeded by generation of electric current at that time.
