Abstract
A locking mechanism for a motor is provided. The locking mechanism includes a detent mounted on a shaft coupled to the motor, and a solenoid including an electromagnetic coil, a plunger, and a spring that holds the plunger at an extended state. The plunger engages the detent at the extended state when no voltage is applied, and the spring is configured to exert a predetermined force for the plunger to engage the detent to lock the shaft. The plunger retracts away from the detent to allow rotation of the motor shaft when a voltage is applied to the solenoid.
