A braking mechanism for an electric motor includes an electromagnet configured to be selectively energized in response to a control signal. The braking mechanism also includes a first braking member coupled for co-rotation with an output shaft of the electric motor. The first braking member is configured to movable relative to the output shaft between a first position and a second position. The braking mechanism also includes a second braking member rotationally fixed relative to the first braking member. When the electromagnet is energized, the electromagnet causes the first braking member to move from the first position to the second position. The first braking member engages the second braking member to brake the electric motor in one of the first position or the second position.
