Abstract: A hybrid inverter for a slip energy recovery system for a wound rotor motor employs six thyristors (for 3 phase operation) or equivalent devices. Three of these are operated continuously in the inversion mode, the other three being operated from zero degrees to 180 degrees. The result is that a characteristic that is identical to a semi-converter is obtained except in the inversion mode. The hybrid inverter produces zero quadrature current at the full speed of the wound rotor motor and, as desired, zero volts at maximum current and maximum volts at zero current.

Abstract: A starter drive for internal combustion engines. The starter drive is mounted within the starter housing and connected to the motor driven shaft. The shaft has a screw thread formed thereon near the armature of the starter and a cylindrical end portion. A screw sleeve member cooperatively engages the screw thread of the motor driven shaft. A ring armature member is centrally mounted to the threaded screw member. A unidirectional clutch member connects the screw sleeve member, the ring armature member and the pinion gear. An engaging member holds the ring armature member to the starter housing when the pinion gear is advanced axially along the motor driven shaft by the rotation of the motor when the motor is activated. Thus, the pinion gear engages the engine ring gear such that the pinion gear is held in mesh with the ring gear and the total motor torque is transmitted to the ring gear until the motor is deactivated.
