INverter for electric motor

 With the use of an inverter for motor, it becomes possible to freely change the rotation speed and torque of motor.

 The inverter can be used for the energy-saving operation of radiator fans and driving a vehicle in which a large change in torque and rotation speed is required.

 By controlling a motor with an inverter, the motor can be converted to a generator to produce electricity.

 It can be said that a motor, which was supposed to rotate at a constant speed, acquired intelligence by its combined use with an inverter.

 The power devices used in the inverter are controlled by a high-performance microcomputer or DSP (Digital Signal Processor).

Sawafuji Electric manufactures the inverters with several tens of watts to several tens of kilowatts.
