Organizing and summarizing search results for youA soft starter is used to gradually start an electric motor by reducing the starting current. It limits the surge of current during acceleration, resulting in a safer and smoother start-up. The input voltage is ramped up slowly, allowing the motor to start with less stress.4 Sources
