TYFB Low-Speed High-Torque Flame Proof PMSM With Variable Frequency Drive

TYFB series low-speed, high-torque dust explosion-proof permanent magnet direct-drive synchronous variable frequency motor is a new type of permanent-magnet direct-drive synchronous motor developed by our company for the market demand of low-speed and heavy-duty equipment. The rotor is excited by permanent magnet materials, which realizes low-speed high-torque power transmission. , The frequency converter is used to control the motor. In the application of the mill, the reducer can be removed and the pinion can be directly driven. It has the advantages of compact structure, large starting torque, high efficiency, stable operation, high reliability, low noise, convenient installation, etc., and basically realizes maintenance-free. The change of transmission mode, removing the reducer, simplifies the transmission chain of the mill, reduces the The maintenance cost of the reducer is reduced, the intermediate links are removed, and the overall transmission efficiency of the mill is improved.

This series of permanent magnet motors adopts permanent magnet material excitation. Compared with traditional current excitation motors, the power factor is significantly improved, the stator current and stator resistance losses are reduced, and there is no rotor copper loss during stable operation. In the 25%-120% rated load range, high efficiency and power factor can be maintained. The energy-saving effect during light-load operation is more significant. Compared with the characteristics between efficiency, power factor and load rate of permanent magnet motor and asynchronous motor, it has obvious advantages.

TYFB series low-speed, high-torque permanent magnet direct-drive variable frequency motors are used in all power transmission equipment that needs to provide low-speed, high-torque, and high-power in the industrial field, especially in my country's mill machinery equipment. Systematic design of the drive and transmission links of mechanical equipment, based on the unique electromagnetic characteristics and vector control method of permanent magnet motors, comprehensive power supply characteristics and system cost performance, developed a complete set of drive and control system solutions to optimize motor design. , reduce material costs, reduce power consumption, and produce significant economic benefits. Eliminate the mechanical deceleration device, greatly reduce the maintenance workload of the equipment, and at the same time enhance the operational reliability and sustainability of the motor from the design, and reduce the maintenance cost after it is put into operation.

Features
1. Simple structure, small size, light weight, stable and reliable operation;
2. The motor has high power factor and high efficiency, and maintains high efficiency and power factor within the rated range of 20%-120%, without adding a power compensator;
