The Vital Role of Motor Drive Controllers in Industrial Automation

A motor controller is a device that converts electrical energy into mechanical energy for operation. Motor controllers are becoming more and more widespread in electrical equipment and mechanical systems. Their main role is to control the operating state of the motor so that it can smoothly perform various motions, speed and torque regulation, inverter control, as well as to protect and monitor various aspects of the motor system. Motor drive controllers are widely used in electric motors as well as in various areas of system manufacturing, machine manufacturing and modern process technology. In April 2021, Semipower passed the IATF16949 certification of the automotive quality management system.
