Means for assembling electric motors with reduced end-play

摘要

A method of manufacturing fractional horsepower motors involves using each stator to customize the length of a rotor/shaft to match the thickness of the specific stator with which it will be used. This is accomplished by providing a fixture which receives the stator in a gauging position. The rotor/shaft, with a compressible member thereon, is placed on the fixture which is then closed over a distance fixed by the gage formed by the stator. As the fixture closes, a compressible member is compressed to exactly fit the length of the rotor/shaft assembly to the stator thickness. The compressible member is a preferably nylon or metal plug which is pushed into a metal cup and mounted at the end of the rotor as the fixture closes.
