Abstract: Torque generating apparatus and method for automotive applications. A brushless DC motor is design optimized to operate at a design voltage, Vs, along an optimal speed/torque profile. A DC/DC converter is provided for supplying power at an alternate voltage, Va, to enable motor operation at speed/torque combinations not on the optimal profile. A switch is provided to enable the motor to be operated selectively at either of the two voltages.

Abstract: A stator core for a variable reluctance motor. The stator core having a number of stator lamina joined together in a direction along a longitudinal axis. Each of the stator lamina include a number of circumferentially spaced-apart pole pieces and a circular member joined to each of the pole pieces at an intermediate portion thereof so as to define a flanged portion which extends radially inwardly from the circular member.

Abstract: This invention deals with a system and method for manufacturing a drive gear having a plurality of teeth in cross section where the teeth are situated on a drive shaft in a substantially parallel manner. The drive gear is characterized in that the teeth are substantially parallel to each other and contact mating driven teeth at points which define an arc which is not concentric about an axis of the driven gear. The drive gear is characterized in that it has multi-tooth contact points which do not contact the teeth of the mating gear at exactly the same contact point on the mating teeth, thereby lengthening the life of the driven gear as well as distributing the torque load to a plurality of teeth. A method and procedure for generating a drive gear having the features of the present invention is also disclosed.

Abstract: A motor assembly includes an output shaft having a first central axis, the output shaft including a first coupling member. The motor assembly further includes a secondary shaft having a second central axis, the secondary shaft including a second coupling member which is coupled to the first coupling member, wherein the first central axis and the second central axis are non-colinear when the first coupling member is coupled to the second coupling member during operation of the motor. A method of coupling an output shaft of a motor to a secondary shaft is also disclosed.
