Abstract
PURPOSE: To reduce an amount of loss, with a speed control operated by varying a voltage applied to the motor, when in a range with three-phase induction motor used for hoist operating a hoist down at a speed exceeding the synchronous speed, that is, when in a range of regenerative braking.
