Patent ID: 8278803

Claim:
A motor, comprising: a stator winding assembly characterized by an inner diameter; a rotor assembly having a rotor, a drive shaft and bearings, the rotor assembly fitting so as to rotate within the stator winding assembly, the rotor assembly having a stack length equal to that of the stator winding assembly; a pair of end caps fitting over ends of the stator winding assembly, the end caps seating the rotor assembly at its bearings, with at least one end cap having a central opening through which the drive shaft projects; and a set of guides, distinct from the end caps, attached at respective ends of the stator winding assembly and having dimensions coinciding with the inner diameter of the stator winding assembly to pilot the placement of the end caps such that the rotor assembly is indirectly maintained in a concentric position relative to the stator winding assembly.
