China Soft Starter Manufacturers, Suppliers, Factory

A soft starter is an electronic device used to control the starting current and torque of electric motors. It is designed to gradually ramp up the voltage supplied to the motor during startup, reducing the stress on the motor and associated mechanical components.

The main purpose of a soft starter is to limit the inrush current that occurs when a motor is started at full voltage. When a motor starts, it typically draws a high current that can cause voltage dips in the electrical system and put a strain on the motor windings and other components. By gradually increasing the voltage, a soft starter helps to mitigate these issues and extend the lifespan of the motor.

Soft starters achieve this by employing solid-state electronics, such as thyristors or silicon-controlled rectifiers (SCRs), to regulate the voltage and current supplied to the motor. The soft starter gradually increases the voltage during startup, enabling a smooth and controlled acceleration of the motor.

In summary, a soft starter is an electronic device used to control the starting current and torque of electric motors. By gradually increasing the voltage supplied to the motor during startup, it reduces the inrush current and minimizes stress on the motor and electrical system. Soft starters provide important functions like motor overload protection and can be widely used in industrial applications to enhance motor performance and efficiency.
