A soft starter is an electrical device used to control the starting and stopping of electric motors. It gradually increases the voltage supplied to the motor, allowing it to start smoothly without sudden jolts. This helps reduce mechanical stress on the motor and connected equipment, extending their lifespan and improving efficiency. Soft starters are commonly used in applications like pumps, fans, and conveyors, where a gentle start is essential. By minimizing inrush current, they also help prevent electrical issues in the power supply system. Overall, soft starters enhance performance and reliability in various industrial settings.
