ZOPTS-658M Training Platform

The AC and DC speed regulation tr*ning device is based on the requirements of the textbook syllabus of "Electric Drive Automatic Control System", "DC Speed ​​Regulation", "AC Variable Frequency Speed ​​Regulation", and "Advanced M*ntenance Electrician (AC and DC Speed ​​Regulation Part)". A set of modern comprehensive motor and drive series tr*ning products launched from curriculum experiments conducted by relevant majors in colleges and universities and vocational tr*ning and technical colleges . The AC and DC speed control experimental device m*nly tr*ns and assesses students' parameter setting and system application capabilities of AC inverters and DC speed control devices. Through the careful design of the AC inverter control circuit and the controlled motor load, students can master communication through experiments. The motor frequency conversion controls various typical working states; through careful design of the m*n loop, control loop and DC motor load of the DC speed regulating device, students can master various typical working states of DC motor speed regulating through practical tr*ning.
