摘　　要：磁粉离合器的控制电路中,传统的控制电路采用电位计手动调整电流的方式来控制离合器的打滑力矩,灵活性较差,不易于使用和维护。针对该问题,提出了一种基于改良型压控电流源的磁粉离合器控制电路。该电路可以通过处理器控制数模转换器(Digital to AnalogConverter,DAC)来输出不同的电压来调节输出电流,从而达到调整磁粉离合器打滑力矩的目的。In the control circuit of magnetic powder clutch,the traditional control circuit uses potentiometer to manually adjust the current to control the slipping torque of clutch,which has poor flexibility and is not easy to use and maintain.To solve this problem,a control circuit of magnetic powder clutch based on improved voltage-controlled current source is proposed.The circuit can control the Digital to AnalogConverter(DAC)by the processor to output different voltages to adjust the output current,so as to achieve the purpose of adjusting the slip torque of the magnetic powder clutch.
