ACTUATOR
First Claim
1. An actuator comprising:
- a housing;
a motor assembly in the housing, the motor assembly including a rotatable motor pinion and a stator surrounding and spaced from the motor pinion;
a gear assembly in the housing including a first rotatable gear coupled to the motor pinion and a second rotatable gear adapted for rotation in response to the rotation of the motor pinion and the first rotatable gear;
the motor pinion and the first and second gears being positioned in a generally horizontally co-linear, and side-by-side relationship; and
a sensor assembly including a substrate in the housing.

Abstract
An actuator comprising a housing defining an interior cavity for a motor assembly including a rotatable motor pinion and a stator, a gear assembly including a plurality of rotatable gears, and a sensor assembly including a substrate. The motor pinion includes a yoke, a motor magnet surrounding the yoke, and a sensor magnet. In one embodiment, the second gear is located between and coupled to both the motor pinion and the first gear. Each of the motor pinion and the plurality of gears is mounted for rotation on respective shafts. In one embodiment, each of the shafts includes a stop that limits the axial travel of the motor pinion and the plurality of gears. The motor pinion and the plurality of gears are positioned in the housing in a longitudinal, co-linear, and side-by-side coupling and meshed relationship.
