Abstract
A method of securing a stator winding such that it has improved heat dissipation performance includes steps of inserting a stator winding into a stator core soaking these components in a varnish tank while being held together as one, and after the varnish has soaked into the stator winding , withdrawing the winding and core from the varnish tank. Then a mandrel comprising an outer peripheral pressing portion made by wrapping a fluororubber around an outer periphery of a mandrel body made of a fluoroplastic, is inserted into the stator winding. After this, the varnish is heat hardened with the stator core, the stator winding, and the mandrel all held together as one. In so doing, the outer peripheral pressing portion is deformed with irregularities replicating the inner periphery of the stator winding . Hence on the inner peripheral side of the stator winding, the varnish resin hardens with the irregularities retained. As a result, the effective inner peripheral surface area of the stator winding with the hardered varnish is increased, and heat dissipation is thus improved.
