What is the Soft starter?
Soft starters A soft starter is a solid-state device that protects AC electric motors from damage caused by sudden influxes of power by limiting the large initial inrush of current associated with motor startup. They provide a gentle ramp up to full speed and are used only at startup (and stop, if equipped). Ramping up the initial voltage to the motor produces this gradual start. Soft starters are also known as reduced voltage soft starters (RVSS). Soft starter applications Soft starters are used in applications where: Speed and torque control are required only during startup (and stop if equipped with soft stop) Reducing large startup inrush currents associated with a large motor is required The mechanical system requires a gentle start to relieve torque spikes and tension associated with normal startup (for example, conveyors, belt-driven systems, gears, and so on) Pumps are used to eliminate pressure surges caused in piping systems when fluid changes direction rapidly Benefits of
