Can't soft starter and inverter be clearly separated? Let's learn together today.


The inverter changes the output frequency and voltage at the same time, that is, it changes the n0 on the motor running curve, so that the motor running curve moves down in parallel. Therefore, the frequency converter can make the motor with a smaller starting current, and at the same time make the motor starting torque reach its maximum torque, that is, the frequency converter can start the heavy load.

Development history of motor soft starter


Motor soft starter is a new type of starting equipment with the international advanced level, which is designed and produced by using power electronic technology, micro-processing technology and modern control theory.

Energy-saving principle of motor soft starter


Motor soft start is through the use of voltage reduction, compensation or frequency conversion and other technical means, to achieve the smooth start of the motor and mechanical load, reduce the impact of the starting current on the power grid, so that the power grid and mechanical system can be protected.
