Abstract
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 a motor shaft of the electric motor, the first braking member being configured to selectively translate axially relative to the motor shaft between a first position and a second position. The braking mechanism also includes a second braking member located between the first braking member and the electromagnet and rotationally fixed relative to the first braking member. When the electromagnet is energized, the electromagnet causes the first braking member to translate from the first position to the second position at which the first braking member engages the second braking member to brake the electric motor.
