High-voltage High-Efficiency Permanent Magnet Variable Frequency Synchronous Motor

The stator structure of the high-voltage and high-efficiency asynchronous start permanent magnet synchronous motor is similar to that of the ordinary Y series asynchronous motor. The company's R&D team uses modern high-performance motor design theory and design technology to optimize the core and winding; the rotor is placed in the high-performance rare earth “Magnetic King”, which optimizes the squirrel cage structure and can produce higher than ordinary asynchronous motors at rated voltage and rated frequency. Starting torque.

Working Principle

The rare earth "Magnetic King" is recognized as the world's most permanent magnet material with the highest magnetic energy content, saturated magnetization, and presents a "permanent magnetic field". After the motor is installed, no reactive current excitation current, permanent magnetic field of "Magnetic King", interaction with the three-phase current of the winding, and stable electromagnetic torque are generated to drive the load.

This structural feature of the high-voltage high-efficiency permanent magnet motor makes the power factor high. Under the condition of ensuring the same output power, the current is significantly reduced, the resistance loss of the winding is reduced, and there is substantially no rotor loss during operation, which exhibits remarkable high efficiency and energy saving characteristics. Due to the reduction of the total loss, the temperature rise is reduced by more than 30K compared with the conventional asynchronous motor, and the operating life is prolonged.
