ABSTRACT:
A motor assembly includes a stationary assembly having a plurality of winding stages adapted to be electrically energized to generate an electromagnetic field and a rotatable assembly including a plurality of permanent magnet elements in magnetic coupling relation with the stationary assembly. The motor assembly also includes first and second substantially flat end members parallel to each other and having inner facing sides between which the stationary assembly and the rotatable assembly are located. Each of the members has an outer side opposite its inner side. Control circuitry is connected to the winding stages and positioned adjacent the outer side of the first member, for applying a voltage to one or more of the winding stages at a time and for commutating the winding stages in a preselected sequence to rotate the rotatable assembly about an axis of rotation. A cap on the outer side of the first member forms a closure with the first member within which the control circuitry is located. A connecting element engages the second end member and the cap and is adapted to urge the second end member and the cap toward each other thereby supporting the first end member, the stationary assembly and the rotatable assembly therebetween. Alternatively, an adapter having first and second opposite sides may be positioned between the first end member and the cap.
