Molded motor

摘要

In a molded motor having a motor frame (16) molded by covering a stator composed by a straight core (16) with a molding resin (12), the straight core has a stack of laminas (1) each having a plurality of tees (3) projecting from one long side of a belt-shaped back yoke and a V-shaped cut formed between every two adjoining tees along the back yoke and on its side from which the tees project. The straight core has an insulating layer formed by pre-molding from an insulating resin on its portions excluding at least the inner periphery of each tee. The straight core also has a winding (8) formed about each tee having the insulating layer formed thereon. The stator is formed by bending the straight core at the cuts into an arcuate or annular shape, and joining the opposite ends of the back yokes to each other by welding or adhesion.
