PERMANENT MAGNET MACHINE CONTROL SYSTEM

摘要

A permanent magnet (PM) machine system is provided having a PM machine and a controller in communication with the PM machine. The PM machine has a q-axis voltage feedback signal and a pullout torque that represents a peak torque that the PM machine generates. The controller includes a q-axis current regulator that produces a commanded q-axis voltage that is supplied to the PM machine. The controller also includes at least one control logic for monitoring the q-axis voltage feedback signal of the PM machine.
