ABSTRACT:
A motor and a rotatable single phase electromagnetic actuator that has a self aligning shaft that allows for misalignment of actuator parts that would lead to excessive bearing surface wearing. Additionally, the actuator has a rotor, having a first rotor surface; a stator, having a slanted bearing surface opposed the first rotor surface; and a bearing device, mounted on and between the first rotor surface and the slanted bearing surface, positioned and shaped to separate the rotor from the stator and to self align on the slanted bearing surface in a position that substantially evenly distributes bearing loading on the bearing device.
