2025 Top 10 Soft Starter Manufacturers in The World

Introduction to Soft Starters

A soft starter is an electronic device used to control the acceleration of an electric motor. It gradually increases the voltage supplied to the motor during startup, thereby reducing the inrush current and torque surges that typically occur when a motor is started directly across the line. This not only protects the motor and the connected equipment from mechanical stress and electrical damage but also helps in saving energy and improving the overall efficiency of the system. Soft starters are widely used in various industrial applications such as pumps, fans, compressors, conveyors, and other motor - driven equipment.
