With the development of economy, green, low-carbon and energy saving have become a melody. All industries are actively working to improve production capacity, reduce cost and increase efficiency and eliminate backward production capacity. Therefore, rare earth permanent magnet synchronous motor has entered people's vision. Due to its high efficiency, low loss and energy saving, rare earth permanent magnet synchronous motor is more and more favored by the manufacturing industry; Many motor factories are developing and manufacturing rare earth permanent magnet synchronous motors to help the country's energy conservation, emission reduction and intelligent manufacturing.

Due to the rotor of rare earth permanent magnet synchronous motor, the rotor is equipped with permanent magnet to make it magnetic; It brings some difficulties to the dynamic balance of the rotor. Special dynamic balance equipment is required to reduce the impact of rotor permanent magnet on the balance accuracy of the rotor. Hengda motor has invested in high-precision permanent magnet synchronous motor rotor dynamic balance equipment to help improve the quality of the motor. The support frame and main body of the balancing machine are made of stainless steel to shield the interference of permanent magnet on the balance signal transmission, At the same time, the frequency conversion of the balancing machine speed is adjustable and can be switched freely at low speed and high speed, so as to ensure the quality of rotor dynamic balance of permanent magnet synchronous motor and help improve the manufacturing quality of permanent magnet synchronous motor.
