Abstract
A plugging defeat system for use with a reversible electric motor having a motor shaft. A slipping clutch-type mechanism is used to sense the speed and direction of the motor and to selectively open forward or reverse enabling switches when the motor reaches a predetermined speed. If operating in the forward direction, the clutch mechanism will open the reverse enabling switch, once the predetermined speed is reached, preventing motor reversal until the speed has fallen to a safe level, and vice versa.
