IE4 Low Voltage Ultra High Efficiency Permanent Magnet Synchronous Frequency Conversion Motor

The stator structure of IE4 low-voltage super-efficient permanent magnet synchronous motor is similar to that of 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.

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 High Efficiency Permanent Magnet 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 IE4 ultra-efficient permanent magnet synchronous 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. This is the basic working principle of a permanent magnet synchronous motor.

The basic series of IE4 ultra-efficient permanent magnet synchronous motor is three-phase, 380V, fully enclosed fan air cooling, protection class IP54, class F insulation, installation form IMB3, working system S1. It can meet the requirements of users for other voltage levels 690V, 1140V, protection level, cooling method, installation form, etc. Our company is committed to providing customers with a total solution for the motor drive system. When the customer needs more than 1500 rpm (less than 500 rpm), the inverter is used for power supply.
