MOTOR ARRANGEMENT

摘要

A motor arrangement having a rotor with a north rotor magnetic pole and a south rotor magnetic pole, the rotor being rotatable about a rotor axis between a first rotor position and a second position, the rotor including a first rotor abutment and a second rotor abutment, a stator having a first stator magnetic pole and a second stator magnetic pole, the stator having a first stator condition in which the first stator magnetic pole is a north stator magnetic pole and the second stator magnetic pole is a south stator magnetic pole, and a second stator condition in which the first stator magnetic pole is a south stator magnetic pole and the second stator magnetic pole is a north stator magnetic pole, the first stator condition corresponding to the first rotor position in which the north rotor magnetic pole is proximate the second stator magnetic pole and the south rotor magnetic pole is proximate the first stator magnetic pole, the second condition corresponding to the second rotor position in which the north rotor magnetic pole is proximate the first stator magnetic pole and the south rotor magnetic pole is proximate the second stator magnetic pole, an output member being rotatable about the rotor axis and having a first output abutment engageable by the first rotor abutment to move the output member in a first rotational direction and having a second output abutment engageable by the second rotor abutment to move the output member in a second rotational direction, the output member being rotatable relative to the rotor to a limited extent defined by the first and second output abutments and the first and second rotor abutments, the motor arrangement further including a first stop to limit movement of the rotor past the first rotor position and a second stop to limit movement of the rotor past the second rotor position.
