Application of High Starting Torque Motor Technology During Asynchronous Motor Retrofit

The starting process of asynchronous motor is analyzed and the mechanism of normal asynchronous motors frequently damaged by driving heavy load starting devices is explained reasonably. The ideal starting performance is achieved by improving the electromagnetism design of normal asynchronous motor, using keep stator unchanged, redesigning rotor iron core,guide bar and side ring and optimizing the design. The starting torque of the prime motor is improved, the starting time is shortened, the damage of rotor is avoided. An effective and low-costed way of solving the problem that normal asynchronous motors are frequently damaged when used to drive heavy load starting devices is found hereby.
