When the motor is just started, the rotation is static; The rotating magnetic field of the AC brake motor cuts the rotating magnetic field at a relative speed, so that the rotating magnetic field senses a high potential and flows a large current, which is also called the starting current; Here is a simple understanding of the requirements of Senli Motor.

       The starting current of the AC brake motor may cause the output voltage of the power supply device to fluctuate or trigger overcurrent protection, resulting in failure to start normally. After the brake motor is started, the stator current will quickly stabilize as the speed increases. It works within the rated current range, and chooses a larger power supply to avoid the shock of the starting current, which will cause waste.

       The effective way to deal with the impact of starting current is to use soft starting, by slowly increasing the operating voltage of the motor to achieve the speed, and gradually reaching the expected set value, can significantly reduce the motor starting current to ensure that the test is carried out normally.
