ABSTRACT:
A sensorless motor control algorithm that single-handedly permits operation over the entire speed range from low speed to high speed. This “fusion” algorithm seamlessly fuses the position data generated respectively by high speed and low speed sensorless algorithms. The resulting sensorless drive permits effective position sensorless operation over the entire speed range of a PM motor.
