Permanent Magnet Motor

Using a voltage source motor control method, the 50Hz power frequency current passes through the rectifier and is supplied to the three-phase winding of the motor by a three-phase inverter. The rotating magnetic field synthesized by the three-phase symmetrical current interacts with the magnetic field generated by the rotor permanent magnet to generate torque, and the rotor is dragged to rotate at a synchronous speed of n=60f/p.


Technical parameters
1. Proprietary waterway structure
2. With independent explosion-proof chamber
3. The stator coil adopts a high-pressure structured formed coil
4. The rotor adopts a built-in tangential magnetic circuit structure
5. High temperature resistance and high performance permanent magnet materials
6. The shaft is made of high-strength alloy steel
7. The rectifier and inverter of the frequency converter adopt a modular structure, which is convenient for on-site maintenance
8. The control box is equipped with a Chinese LCD display, which can display system graphics, operating parameters, fault information, and historical record queries; Various settings and operations can be completed through the screen

9. Equipped with automatic parameter storage function. After the main power supply is powered off and restored, the original set parameters of the frequency converter remain unchanged, and there is a fault recording function. The storage capacity is not less than 100 pieces
10. Equipped with cable connectors on the inlet and outlet sides
11. Has a high starting torque, with a maximum starting torque greater than 220%; Controllable torque greater than 125% at low frequencies; Maximum overload of 250%; Overload current 1.2Ict (long-term continuous operation); Overload current 1.5Ict (2 minutes); Overload current 2Ict (1 minute); Torque response time less than 10 milliseconds
12. The total harmonic content generated by the frequency converter is less than 3%
Excellent motor control modes with efficient and energy-saving design, as well as selectable output DU/DT and sine wave filters, enable power factor greater than 0.95 and self efficiency of over 98%.
