Softstarters

Softstarters (also seen as soft starters) for motors are devices used to temporarily reduce the load and torque on a motor during its start-up. This helps to protect the motor and extend the system’s working life by reducing mechanical and electrodynamic stresses on the power cables and electrical distribution network.

Motor softstarters

Motor softstarters can consist of electrical or mechanical devices (or a combination of both). Mechanical softstarters include clutches and several types of couplings using fluid, magnetic forces to transmit and control torque. An electronic softstarter on the other hand is designed to reduce torque by reducing the voltage or current input.

Electronic softstarters

Electronic softstarters can use solid-state devices to control current flow and, therefore, the voltage applied to a motor. A solid-state softstarter can control one or more phases of the voltage applied to the induction motor.
