Project Description

400kw-600kw soft starter


The motor soft starter is the use of power electronic technology, micro processing technology and modern control theory and the design of new production equipment starting with the current international advanced level. The product can effectively limit the starting of AC asynchronous motor starting current, which can be widely used in fan and water pump, conveying type and the compressor load, is the traditional star delta conversion, autotransformer step-down buck, magnetron device ideal products.

A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the power train and electric current surge of the motor during start-up.
