Large starting torque, providing 0.5Hz 150% rated torque, easy to start the spindle motor;

It has the advantage of fast torque response, and when the load fluctuates, the current fluctuation is small;

It has good overload capacity and environmental adaptability, and has high operational reliability;

With excellent speed control accuracy, the control accuracy is 0.2%, and accurate speed control is realized;

Excellent current limiting characteristics, strong overload capacity, can effectively reduce frequency conversion overload, overcurrent protection, and maximize production continuity;

It has strong environmental adaptability, and the completely independent air duct design can greatly improve the resistance to harsh environments such as oil pollution, dust and damp heat.
