product description

TYJX external rotor series variable frequency drive high-efficiency permanent magnet synchronous motor is a fully enclosed air-cooled motor independently developed and designed by our company for the field of fans. The efficiency index of this series of products reaches the energy efficiency limit value and energy efficiency grade of GB30253-2013 permanent magnet synchronous motor. It is greater than the Class 1 standard and reaches the advanced level of similar products. Due to the excellent magnetic properties of rare earth permanent magnet materials, it does not require external energy after magnetization and can establish a strong permanent magnetic field to replace the electric current of traditional motors. The permanent magnet motor produced by the excitation field is not only highly efficient, but also has a simple structure and reliable operation. It can be small in size and light in weight. It can achieve high performance that traditional motors cannot match (such as extremely efficient, extremely high speed, extremely high response speed), and can be made into special motors that can meet specific operating requirements. The combination of permanent magnet motors with electronic technology and microcomputer control technology can improve the performance of the motor and drive system to a new level, making the motor more intelligent. ization, dataization, and are widely used in various fan fields. Permanent magnet synchronous motors have novel design, compact structure, high efficiency and high power factor, good starting torque performance, energy saving, low noise, small vibration, safe, reliable operation, high efficiency and energy saving, etc. advantage.

Features

Conditions of use: Suitable for various working conditions in the fan field; (The picture is applied to centrifugal fans.)

Energy saving principle

The rotor of the external rotor permanent magnet synchronous motor uses high-performance rare earth permanent magnet materials to generate a fixed magnetic field (generated by permanent magnets and current). The rotating magnetic field of the stator drags the rotor magnetic field (rotor) to rotate, so the rotation speed of the rotor must be equal to the synchronous speed, and no excitation current is required. , excitation winding to achieve high energy efficiency.
