Uneven motor speed is a common problem that can be caused by various factors. However, there is indeed a relationship between uneven motor speed and frequency converter.

The frequency converter changes the operating speed of the motor by adjusting the voltage and frequency supplied to the motor. During low-speed operation, the speed variation of a variable frequency motor is mainly influenced by several factors, including the stability of the power supply frequency, load changes, and the compatibility between the motor and the variable frequency converter. If the parameters of the frequency converter are not set correctly or if the grid voltage fluctuates, it will cause the output voltage of the frequency converter to be unstable, thereby affecting the speed stability of the motor. In addition, changes in load, motor design issues, sensor or feedback control system failures, and other mechanical problems such as bearings, couplings, mechanical transmission devices, etc., can also affect the speed stability of the motor. ?

Therefore, to solve the problem of uneven motor speed, in addition to checking the motor itself, it is also necessary to check whether the parameters of the frequency converter are set correctly and whether the grid voltage is stable. If the problem persists, it may be necessary to replace the high-performance motor and frequency converter, or optimize the parameter settings of the frequency converter to improve the stability of the motor at low speeds.
