ABSTRACT:
In a preferred embodiment, in an electric motor of the type including a cup-shaped housing and a housing mounting plate, the improvement comprising: providing said cup-shaped housing and said housing mounting plate as a monolithic part. In another embodiment, an electric motor, including: first and second stator coils wound, respectively, on first and second bobbins; first and second stator poles closely engaging, respectively, slots defined in the first and second bobbins to radially align, respectively, the first and second stator poles with respect to the first and second bobbins; a central pole structure having formed thereon poles extending in proximity to the first and second bobbins; and alignment structure extending between the first and second bobbins and through the central pole structure to radially align the poles on the central pole structure with respect to the first and second bobbins and the first and second poles. In another embodiment, an electric motor, comprising: two bobbins disposed in a cup-shaped housing, the walls of the housing having a slight taper to permit a central pole structure to be secured in the housing by means of an interference fit. In another embodiment, an electric motor housing having no mounting flanges, including: a cup-shaped housing having a generally open end; and a cover closing the generally open end, the cover fitting within the outer periphery of the cup-shaped housing.
