Technically, a "Soft Start" (as it relates to AC electric motors) is any device that will reduce the toque delivered to the power train. Mechanically, this can be a clutch, fluid drive, magnetic coupling, shot coupling or any one of a variety of devices that allow the motor to start-up Across-the-Line (X-Line or D.O.L.) while slowly applying the shaft torque to the load to avoid "torque shock".
