A park brake, comprising:
- a micro-motor comprising a gear train;
- a first gear coupled to the micro-motor;
- a second gear coupled to a shaft, the first gear configured to operatively engage the second gear, wherein the shaft binds in response to the micro-motor being energized.
An electric motor actuator, comprising:
- an electric motor;
- a shaft coupled to the electric motor
- a sector gear coupled to the shaft;
- a micro-motor;
- a pinion gear coupled to the micro-motor, the pinion gear configured to operatively engage the sector gear.
