Yes, soft starters can effectively reduce the current when the motor starts. Here are its specific functions and principles:

1. Reduce starting current:

When the motor is started directly, the starting current is usually 4 to 7 times the rated current, which may have an impact on the power grid and equipment.

The soft starter gradually increases the motor terminal voltage (usually using thyristor to adjust the voltage) to limit the starting current and make it gradually rise within a lower range. This method reduces the impact of the power grid and protects the equipment and the motor itself.

2. Reduce mechanical impact:

While reducing the starting current, the soft starter can also alleviate the mechanical impact during startup, protect the motor bearings, gears and transmission system, and extend the life of the equipment.

3. Smooth starting process:

The soft starter can adjust the starting time according to the load demand, achieve smooth acceleration, and avoid damage to the equipment due to excessive torque.

4. Applicable scenarios:

Soft starters are widely used in scenarios that require smooth starting, such as pumps, fans, compressors and conveyors, especially in situations where the power grid capacity is small or the equipment is sensitive to current fluctuations.
