Abstract
A method and a circuit for controlling electric power delivered to an electric motor are disclosed. A forward control signal is transmitted when a forward command is received while a forward latch is not set. The forward latch is set and the forward control signal is stopped when a power level of the motor exceeds a threshold while the forward command is received. The forward latch is reset and a reverse control signal is transmitted when a reverse command is received. The reverse and forward control signals are not transmitted when no command is received. A reverse latch is optionally set when the power level exceeds the threshold while the reverse command is received. A winch connected to the motor has a cable wound thereon in a forward direction of the motor and unwound therefrom in a reverse direction of the motor, as controlled by the circuit.
