China Ac Motor For Electric Car Factory – 35kW PMSM Motor for Electric Vehicle – INDEX

1. The external characteristic efficiency curve of PMSM is much higher than that of asynchronous motor in light load, which is the biggest advantage of PMSM in energy saving compared with asynchronous motor.Because the motor when the driving load,usually rarely situation is run at full power, this is because: on the one hand, users in the model selection of the motor, is generally based on the limit of load conditions to determine the motor power, and limit condition is a chance is very few, at the same time, to prevent motor burn out when abnormal condition, the user will also further to the motor power leave allowance;On the other hand, in order to ensure the reliability of the motor, the designer usually leaves a certain power margin on the basis of the power required by the user when designing the motor. As a result, more than 90% of the actual running motor works below 70% of the rated power, which leads to the motor usually working in the light load area.For the induction motor, its efficiency is very low in light load, and the PMSM in the light load area, still can maintain a high efficiency, its efficiency is more than 20% higher than the asynchronous motor.
2. The rotor structure of PMSM is diverse and flexible, and different rotor structures often bring their own performance
characteristics, so rare earth PMSM can choose different rotor structure according to the use needs.Permanent magnet synchronous motor (PMSM) has a series of advantages such as small size, light weight, high efficiency and energy saving in a certain power range
