Abstract :
This paper examines the basic operation of a self-controlled synchronous motor driven by a three-phase MOSFET inverter with the field winding located in the DC link, yielding inherent series characteristics like a DC series motor. A new approach to the analytical and experimental study of the drive with the switches conducting for both 120° and 180° is presented, and typical results, both simulation and experimental, are shown and the performance characteristics compared. The effect of shifting the rotor position sensor is studied for both cases, as well as for four-quadrant operation. It is observed that the resulting drive system is simple, able to operate with reduced torque ripples and voltage spikes, and the characteristics of the drive are well suited for traction/transit propulsion applications and battery/flywheel energy storage systems
