The Characteristics Of Premium Efficiency Permanent Magnetic Synchronous Motor

1. Energy-Efficient
Synchronous motor has the characteristics such as high efficiency, high power factor, high reliability. The efficiency within the range 25%-100%load is higher than ordinary three-phase asynchronous motor about 8-20%, and the energy saving can be achieved 10-40%, the power factor can be increased by 0. 08-0. 18.

2. High Reliability
Because of permanent magnetic rare earth materials, which can effectively avoid the magnetic field imbalance and axial current of the rotor broken bar, and make the motor more reliable.

3. High Torque, Low Vibration And Noise
Permanent magnet synchronous motor with overload resistance(above 2. 5 times), due to the nature of the permanent magnet performance, make the motor synchronization in the external power supply frequency, current waveform, torque ripples obviously decreased. When using together with the frequency converter, the electromagnetic noise is very low, and comparing with the specifications of the asynchronous motor to reduce 10 to 40 dB.

4. High Applicability
The permanent magnet synchronous motor is widely used, which can directly replace the original three-phase asynchronous motor because of the installation size is the same as three-phase asynchronous motor. It can also meet various high-precision synchronous speed control situations and various high requirements of frequent starting. It’s also a good product for energy conservation and saving money.
