Brushless Synchronous Propulsion Motor 680455

The development of a brushless synchronous motor with d-c motor characteristics suitable for vehicle propulsion applications is described. The motor is statically commutated, using thyristors triggered by rotor position logic. It may be operated from d-c power sources such as batteries or from a-c sources such as engine driven alternators, depending on the commutation circuit used with the motor.
The motor has high speed capability, coupled with high torque ability, thus providing the operating range required for severe applications such as military and off highway vehicles.
The three basic elements of the motor system: the motor, power converter, and trigger circuits are discussed in detail. Mechanical, electrical, and control characteristics are reviewed.
Performance data on motors built for vehicular application are also presented.
