Variable frequency motor is also called variable frequency speed regulating motor. We use common in productionThree-phase asynchronous motorThe function of speed regulating motor can be realized by adding frequency converter. Due to the particularity of the inverter power supply and the needs of the system for high-speed or low-speed operation, fast dynamic response, etc., the motor as the main body of the production machinery has strict requirements in electromagnetic, structure, insulation and other aspects.

       Variable frequency speed regulationThree-phase asynchronous motor manufacturersIn the design process, we must first consider whether the motor and the inverter can be well matched, and have good operating performance in a wide frequency range. Therefore, more effective materials such as electromagnetic wires and silicon steel sheets need to be used than ordinary motors. Due to the damage of the inverter power supply to the motor insulation, its insulation requirements become higher. In order to improve the reliability of the motor, its insulation grade is generally selectedFLv.

       It is characterized by the frequency can be adjusted according to the load to change the speed, low voltage inverter motor can reduce the frequency, so that the motor reliable start; Where the load is light, it can be used to reduce the frequency to reduce the speed and current, thereby saving power.
