Is it normal to start if the motor can rotate after being energized? After the three-phase asynchronous motor is connected to the power supply, the normal speed is reached, and the speed is close to the rated speed before it is considered normal starting. So what should the motor pay attention to when starting, today, we will understand it together with Senli Motor Xiaobian.

       The starting current and starting moment of the motor depend on the starting mode, and of course, it is also proportional to the blocking current or the blocking torque, and the blocking current or the blocking torque is only determined by its own parameters, and has nothing to do with the applied resistance moment. But the extra drag moment is large, it can makeThree-phase asynchronous motorThe time (starting time) experienced from the static start to the rated speed is extended, resulting in increased heat, therefore, when the resistance moment is too large, it is not appropriate to frequently start continuously to avoid overheating of the winding.

       The normal starting driver of three-phase asynchronous motor should pay attention to these two rules:

       The starting torque must be greater than the load torque, and there must be a certain difference to generate sufficient angular acceleration, so that the motor can start from a standstill and quickly reach a stable speed. If the starting torque is not large enough, the motor can not reach a stable speed, or even start at all.

The starting current cannot be too large, otherwise it will cause the terminal voltage of the power supply transformer to drop too much, affecting the normal operation of other electrical equipment supplied by the same transformer.
