Three-phase Induction Motor Frequency Control Method And Applications

- Apr 15, 2016 -

Motor stator frequency control is to change the frequency of the power to change its method of speed synchronous speed. Frequency control system is mainly to provide variable frequency equipment

Power inverter, the inverter can be divided into AC - DC - AC inverter and AC - AC converter two categories, most of the current domestic use of AC - DC - AC inverter. Features:

High efficiency, speed the process without additional losses;

Wide range of applications, can be used for cage asynchronous motor;

Speed range, features a hard, high accuracy;

Technical complexity, high cost, difficult maintenance and overhaul.

This method is suitable for applications requiring high accuracy, good speed performance occasions.
