| Abstract: | A speed servo system of rare earth permanent magnetic brushless square wave DC motor is discussed.The system is mainly made up of the MCS 8098 single chip microprocessor which is used as the principal control device,and a GAL is utilized to compose the control circuit.In addition,IGBT used as the main circuit's power switch component and its driver EXB840 composes the power transition circuit.This system fulfills the motor servo control based on PWM single pole half modulation.Both the hardware composition and software function of the system are discussed.Especially the logic of GAL is analyzed in detail,which is used to form six route PWM waves,to change phase quickly and to change motor's rotating direction.Duning the experiment this system operated with stability,and the function of speed regulating is good. |
