Soft Starters
Motors draw significantly higher currents than their nominal currents during startup, posing a considerable risk to the grid. This not only strains the grid but also causes electrical and mechanical wear on the motors. As a result of this wear, the lifespan of the motors decreases significantly. Therefore, to reduce potential faults, soft starter devices have been developed.
ABB soft starters increase the lifespan of motors by protecting them from electrical stresses. They achieve this by optimizing the starting current, which traditional starting methods often subject the motor to excessive stress. Soft starters allow motors to operate under controlled conditions with low currents. The most significant advantages of soft starters over star-delta starters are their compact size and the ability to provide smoother control due to being parameterized according to the connected motors.
