It is believed that whether the motor can start successfully is related to the performance of the soft starter
1. The starting torque of the motor plays a decisive role in the load of the starting motor, and the torque of the motor is related to many factors.
2. As a voltage regulator, the motor soft starter can only change the control quantity of the motor stator voltage, and the motor torque is proportional to the square of the stator voltage. Changing the stator voltage also changes the motor torque. The principle is fixed, each brand of soft starter is designed according to this principle, and has nothing to do with its product performance or quality.
- 3.On the issue of starting torque, as long as the soft starter is not faulty, if the motor cannot start the load, it has nothing to do with its product performance or quality
When the motor cannot start the load, it is considered that the capacity of the soft starter is insufficient, and the capacity of the soft starter should be increased.
1. For the motor, the large capacity of the motor also reflects that it can output a larger driving torque. For the soft starter, this is not the case. The capacity of the soft starter only represents the maximum starting capacity that it can withstand. As for the actual output torque, it depends entirely on the motor itself.
- 2.The soft starter is only a power source, not a driving mechanism, and cannot provide driving torque; even if the soft starter has a large capacity, the motor capacity is too small and cannot start successfully.
It is considered that the smaller the starting current, the better the performance of the soft starter with less voltage drop in the grid.
1. The size of the motor starting current depends entirely on the load. The motor starting current must be greater than the motor current determined by the driving torque required by the load to start successfully.
- 2.Under the premise that the grid conditions remain unchanged, the size of the grid voltage drop completely depends on the size of the starting current of the motor.
