ABSTRACT:
In summary, the stepper motor of this invention comprises a rotor anbd stator both mounted in a single housing (which may be a part of the base casting as described in the incorporated application) the bearings supporting the rotor for rotation within the housing both being located on the rotor shaft on the same side of the rotor adjacent one another, the opposite end of the single housing being covered with a sealed plastic cover. The bore of the lamination stack that forms the stator is piloted by machined surfaces into a high tolerance fit within the housing, and clamped in place with a simple wave washer/snap ring combination.
