large starting torque
large overload multiples
high efficiency, power factor close to 1
reactive power loss
small size

Characteristics: is a large starting torque, large overload multiples, high efficiency, power factor close to 1, reactive power loss, small size, light weight, low-speed and long-term operation is not heat, particularly suitable for electric vehicles to reduce weight and save battery power, load changes in the road, continued to extend the work of driving mileage requirements.
