Abstract
Steering apparatuses, actuator apparatuses, stators, and electric motors are disclosed.
Claims23
An actuator apparatus comprising:
- an actuator body;
- an actuator ram movable relative to the actuator body in response to actuation of the actuator;
- and
- a force sensor operable to measure a force applied by a force-transfer body onto the actuator ram;
- wherein:
- the actuator is operable to actuate in response to the force applied by the force-transfer body;
- the actuator comprises a motor operable to actuate the actuator;
- the motor comprises an output shaft;
- and
- the apparatus further comprises a threaded shaft coupled to the output shaft of the motor and threadedly coupled to the actuator ram such that rotation of the output shaft of the motor causes actuation of the actuator.

An actuator apparatus comprising:
- an actuator body;
- an actuator ram movable relative to the actuator body in response to actuation of the actuator;
- and
- a force sensor operable to measure a force applied by a force-transfer body onto the actuator ram, wherein the force sensor is operable to sense the force in response to a position of the force-transfer body relative to the actuator ram and the actuator is operable to actuate in response to the force applied by the force-transfer body.
