Abstract Asynchronous motor has an extensive application in manufacture. The efficiency is quite low when the motor is running under the rated load. Dynamically adjusting the terminal voltage of the motor according to the change of the load can greatly reduce the consumption, and thus improve the efficiency. This paper provides design of the soft start energy-saving controller of motor, which can be used in energy-saving, soft start and running protection. The controller needs a low cost in hardware, but the function is powerful. This paper proposes the software and hardware design scheme of the controller.
