Abstract
A motor arrangement includes a solenoid disposed within a cavity of the motor stator. The solenoid is configured to axially move the motor shaft arrangement. In certain examples, the solenoid causes the motor shaft arrangement to selectively engage a torque limiting arrangement or other device. The motor shaft arrangement may be biased into engagement with the device.
Claims20
A motor arrangement comprising:
- a motor housing having a longitudinal axis;
- a motor disposed within the motor housing, the motor including a motor stator and a motor rotor;
- a motor shaft disposed within the motor housing and extending through the motor stator along the longitudinal axis of the motor housing, the motor shaft being axially movable relative to the motor housing along the longitudinal axis between a first position and a second position;
- a biasing member biasing the motor shaft towards the first position;
- a solenoid plunger axially fixed relative to the motor shaft so that the solenoid plunger moves in unison with the motor shaft between the first and second positions, the solenoid plunger being formed of magnetic material;
- and
- a solenoid coil disposed within the motor housing in at least partial radial alignment with the motor stator, the solenoid coil being configured to move the solenoid plunger towards the second position against the bias of the biasing member when energized.
