The present disclosure relates to mechanical braking mechanisms used in electric motor applications. The present braking mechanisms may be configured as non-back-drivable mechanical brakes and provide immediate braking of the motors. According to one embodiment, a mechanical brake assembly for an electric motor may include a female disk including a groove and an abutment and a male disk including a projection, the male disk being in mechanical communication with a rotor of the electric motor. When the electric motor is energized, the projection of the male disk is configured to rotate with the rotation of the rotor of the electric motor, but when the electric motor is de-energized, the projection of the male disk is configured to travel within the groove of the female disk and abut the abutment of the female disk, thereby reducing the rotation of the rotor of the electric motor.
