Abstract: A split slip ring assembly formed from first and second halves of a slip ring having a contact surface for rotational engagement with a stationary brush element for transferring electrical signals there between. The contact surface has a smooth surface at the junction of the first and second halves. A fastener locates the first and second halves to form a ring shape. An electrical contact on the ring carries electrical signals between the slip ring and the brush element. An alignment element aligns the first and second halves to form the smooth surface at their junction.

Abstract: A stator 60 is rotated in a direction opposite to that of a rotor 20 to improve output of a generator 9. A stator 60 is rotationally fixed to a main shaft 10. A rotor is fixed to the main shaft rotated by outer force. A main gear 25 is fixed to the main shaft. A ring gear 32 is fixedly positioned with respect to the stator. Pinion gears 43 are disposed between the mains shaft and the ring gear. Rotation of the main shaft in a forward direction rotates the stator in a reverse direction. A pair of slip collars 4a, 4b are concentrically mounted to the rear cover 71 that concurrently rotates with the stator. Output circuits 6a, 6b, 6c of the stator coils 5a, 5b, 5c are connected to the slip collars. Brushes 7a, 7b for slip collars are connected to a rear-side base member 55 fixedly secured to a base plate 50. Electricity is output through the brushes for slip collars.

Abstract: Disclosed herein is an apparatus of a contra rotating generator. The contra rotating generator comprises a cylindrical armature supported on an inner shaft. The inner shaft rotates in a first direction. A cylindrical magnetic field rotor is supported on an outer shaft. The outer shaft is oriented coaxially to the inner shaft. The outer shaft contra rotates opposite to the first direction. A plurality of cam followers maintains uniform air gap between outer surface of the cylindrical armature and inner surface of the cylindrical magnetic field rotor. The uniform air gap prevents mechanical contact between the cylindrical armature and the cylindrical magnetic field rotor. A sprag clutch prevents unidirectional rotation of the inner shaft and the outer shaft. The contra rotation between the cylindrical armature and the cylindrical magnetic field rotor increases relative magnetic flux speed for generating electrical power at low speeds of operation.
