Electronic
Starters/Soft Starters
"A motor soft
starter (when in the context of AC electric motors) is an
electronic device that reduces the torque in the power train
of a motor. In practice this is mechanically a clutch, fluid
drive, magnetic coupling or shot coupling. Electrically a
motor soft starter can be any control system that reduces
the torque by reducing the voltage in, or a device that
causes a change in the motor connection." Click
