Soft starting of electric motors reduces the stress on the connected equipment and results in lower mechanical wear. During starting, these devices limit the torque as well as the current and prevent shock loads, which can arise when using direct starts or Star-Delta starts. In this way, mechanical loads and mains voltage dips can be reliably reduced. Soft starters reduce the motor voltage through variable phase control and increase it in a ramp-like mode from a selectable starting voltage up to mains voltage. The selectable start value means that the soft starters can be adjusted individually to the requirements of the application in question.
