Introduction to the Principles of Permanent Magnet Motors

The product is a permanent magnet motor specially designed for fans，the efficiency index reaches the first-class standard of GB30253-2013 "Energy Efficiency Limits and Energy Efficiency Grades of Permanent Magnet Synchronous Motors",reach the international advanced level of similar products.

Principle:The three-phase symmetrical current passing through the three-phase winding of the stator will generate a stator rotating magnetic field. The rotating magnetic field of the stator generates current in the cage winding for the rotation of the rotor to generate the rotating magnetic field of the rotor. The asynchronous torque generated by the interaction between the stator rotating magnetic field and the rotor rotating magnetic field makes the rotor turn from stationary to rotating. After the start-up is completed, the rotor winding is no longer active, and the magnetic field generated by the permanent magnet and the stator winding interacts to generate driving torque.

Features of drive integrated permanent magnet motor:

High efficiency and energy saving, first-class energy efficiency

High power factor, improve grid quality factor

High power density, convenient for energy-saving retrofit and upgrade

The frequency range is wide, and it can still maintain high-efficiency operation under changing load conditions
Integrated design of driver and motor, simple wiring and better motor protection

Features of permanent magnet direct drive motor:

First-level energy efficiency: high efficiency, the efficiency of permanent magnet motors can easily reach the first-level energy efficiency.

High cost performance: small size, similar cost to traditional motors, but more functions.

High-efficiency work: high-efficiency and wide range of speed regulation. In the speed regulation range of tens to several dry revolutions, the motor is in a high-efficiency working state.

Intelligent energy saving: Through intelligent settings, the problem of "big horse-drawn small carts" of fans can be completely solved.
