摘要：An n-phase DC motor is controlled by converting a motor speed commandsignal generated from a programmed CPU to a motor drive signal and using this motordrive signal to apply DC power to a selected phase of the motor, the amount of appliedDC power being a function of the value of the motor speed command signal. Signalsrepresenting the position and/or speed of the motor are supplied to the CPU from whichthe CPU detects speed errors. The speed command signal then is modified to speed upor slow down the motor so as to reduce the detected errors.
