ABSTRACT:
The method of assembling an electric motor which comprises forming an upper housing assembly by first forming a generally cylindrical shell, forming an end member with an axial tube, mounting the end member on the cylindrical shell with the tube extending axially inwardly, locating the shell radially in an accurate position with respect to the axis of the shell, fastening the end member to the shell to form an upper housing assembly, mounting a radial wall on a hollow shaft, accurately locating a stator on the radial wall so that the stator and the outer diameter of the shaft are in accurate concentric relationship, fixing the stator in this accurate position to form a lower housing assembly, telescoping the upper assembly over the shaft of the lower housing assembly and interposing bearings between the shaft and the tube so that the upper housing assembly is in accurate concentric relationship with the stator.
