Variable frequency speed regulation is a speed regulation method that changes the speed by changing the frequency of the stator power supply of the motor. Generally, the use of frequency converter for speed regulation of three-phase asynchronous motors is also very characteristic, and the following is a simple understanding of Senli Motor Xiaobian together!

       Controlled by frequency converterThree-phase asynchronous motorIt has a wide range of speed regulation, hard characteristics, high precision, and no additional loss in the speed regulation process while increasing efficiency. The frequency converter can be divided into AC frequency converter－Direct current－Ac inverter and AC－Ac inverter two categories.

       The frequency converter can indeed be used in ordinary three-phase asynchronous motors, but it should also be noted here that if the motor runs at a low speed for a long time during use, it is necessary to add an independent cooling fan to the motor, because the ordinary three-phase electricity has its own cooling fan, which cannot effectively meet the cooling of the three-phase motor driven by the frequency converter.
