ABSTRACT:
A complete stator of an electric motor is mounted into a cylindrical sheet metal housing by first mounting the stator between two facing concentric mandrels. The housing, the inner diameter of which is less than the outer diameter of the stator is heated and then mounted over the mandrels and stator. After cooling, the stator and the mandrels are secured in the housing by shrinkage tension. By a smooth rolling of the housing surfaces contacting the mandrels, the tension is released and the mandrels are withdrawn.
