Tyfb Dust Explosion-Proof Permanent Magnet Direct Drive Motor (Permanent Magnet Direct Drive Motor, Low Speed and High Torque Permanent Magnet Drive Motor

TYFB series low-speed, high-torque dust explosion-proof permanent magnet direct-drive synchronous inverter motor is a new type of permanent-magnet direct-drive synchronous motor developed by our company in response to the market demand of low-speed and heavy-duty equipment. The rotor is excited by permanent magnet materials to achieve low-speed high-torque power transmission. Inverter is used to control the motor. In the application of the mill, remove the reducer and directly drive the pinion. It has the advantages of compact structure, large starting torque, high efficiency, stable operation, high reliability, low noise, easy installation, etc., and basically achieves maintenance-free. The change of the transmission method eliminates the reducer, which simplifies the transmission chain of the mill and reduces Reduce the maintenance cost of the reducer, remove the intermediate links, and improve the overall transmission efficiency of the mill. (As shown below)

       This series of permanent magnet motors are excited by permanent magnet materials. Compared with traditional current-excited motors, the power factor is significantly improved, reducing stator current and stator resistance losses, and no rotor copper loss during stable operation. In the range of 25% -120% rated load, it can maintain high efficiency and power factor. Makes the energy saving effect more significant during light load operation. Permanent magnet motors and asynchronous motors have obvious advantages compared to the characteristics between efficiency, power factor and load factor (as shown in the figure below)

 

      TYFB series low-speed, high-torque permanent magnet direct drive variable frequency motors are used in all industrial power transmission equipment that need to provide low-speed, large torque and high power, especially in our country's mill machinery equipment. The system is designed for the drive and transmission of mechanical equipment. Based on the unique electromagnetic characteristics and vector control methods of permanent magnet motors, it integrates the characteristics of power supply and system cost-effectiveness to develop 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, at the same time strengthen the reliability and sustainability of the operation of the motor from the design, and reduce the maintenance cost after putting into operation.
