Abstract
A method of assembling an electric motor in which a rigid first end bell is provided with a bearing seat in which is positioned a bearing. Then a rotor shaft for the motor is positioned in the bearing, and the end bell and rotor assembly is fixed in a holding fixture including a plurality of spaced shims, for further assembly steps. The shims extend upwardly through the first end bell and are spaced therefrom and from the motor shaft. Next a stator is placed on the first end bell with the shims extending therethrough. The end bell and stator are dimensioned such that a gap is established between them when assembled. Then a curable epoxy fluid resin is placed in the gap. Next a second end bell and second bearing held thereby is placed over the rotor shaft and a force applied to the end bell to force tabs on the second bell into the fluid epoxy resin. Finally the epoxy resin is cured to a solid and the end bells are mechanically secured together.
