Soft Starting of Induction Motor

Soft Starting of Induction Motor

This soft starting of induction motor uses opposite parallel thyristors as voltage regulators, which are connected between the power supply and the stator of the device. When the facility is started, our product is gradually increased, and it is gradually accelerated until the thyristor is fully turned on.

Product Details


Product Feature:

This soft starting of induction motor improves the efficiency of its work, and to avoid harmonic pollution for environment.

It realizes that there is no impact during the whole start up process.

It helps to adjust various parameters such as current limit value and start-up time according to the characteristics of the motor load.

It can achieve fast start effect by adjusting the starting current setting value.

Product Description:

This soft starting of induction motor uses opposite parallel thyristors as voltage regulators, which are connected between the power supply and the stator of the device. When the facility is started, our product is gradually increased, and it is gradually accelerated until the thyristor is fully turned on. At the same time, this soft starting of induction motor operates on the mechanical characteristics of the rated voltage to achieve a smooth start, which helps to reduce the starting current and avoid starting the over current trip. There is no doubt that it automatically replaces the completed thyristor with a bypass contactor to provide a rated voltage for the normal operation, which could reduce the heat loss and prolong the service life of the device.
