Large starting torque, 1.5 times the torque output at open-loop 0.5Hz, meeting the requirements of submersible pump operation;

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;

Super power grid adaptability, anti-power grid fluctuation ability up to ±15%, to ensure the stability of output voltage, current, speed  

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.
