Abstract

This invention proposes a rotor position/speed estimation technique for micro permanent magnet synchronous motors. When the motor is operating in the mid and low speed, the stator current is discontinuous. The back emfofthe motor can be detected while the stator current reaches zero. On the other hand, when the motor is operating in the high speed range, the stator current is continuous. Then, by detecting the phase voltage and phase current, the back emf of the motor can be computed. The rotor position can be derived from the back emf. The rotor speed can be computed according to the rotor position with the difference operating. Finally, a closed-loop adjustable speed control can be achieved. The closed-loop drive system has an adjustable speed range from 600 r/min to 36000 r/min.
