Abstract
An electrical switch for an electric machine includes body, a stator fixedly secured to the body and a rotor. The actuator includes a first member securable to the rotor and rotatable with it. The actuator also includes a second member, a first electrically conductive member cooperates with the second member. The actuator also includes a second electrically conductive member. The second electrically conductive member is spaced from said first electrically conductive member when said first electrically conductive member is in the first axial position and electrically engaged with said first electrically conductive member when said first electrically conductive member is in the second axial position.
Claims20
An actuator for an electric machine having body, a stator fixedly secured to the body and a rotor having a shaft rotatably secured to the body and defining an axis of rotation thereof, the actuator comprising:
- a base positionable on a length of the shaft;
- a first member attached to the base, the first member including a plurality of arms hingeably attached to the base each of the arms include a magnet segment having a first end attached to the arm and a second end opposite the first end, the first end having a polarity;
- and,
- a second member including a stem slidably fitted to a housing and a second member magnet, the stem positioned on a stem centerline parallel to the axis of rotation of the shaft such that the stem and the second member magnet are offset relative to the shaft the second member magnet having the same polarity as the second end of the magnet segments such that the second member is repulsed by the first member.
