Patent ID: 7015619

Claim:
A molded motor comprising: a motor frame, molded by covering a stator, having a straight core and a wiring circuit board, with an insulating molding resin or premix therefor; the straight core comprising a stack of laminas, each having a plurality of tees 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 a side from which the tees project; the straight core having an insulating layer, formed by pre-molding from an insulating resin, on portions of the straight core, excluding at least an inner periphery of each tee; the straight core having a plurality of supports, which, together with a portion of the insulating layer, are pre-molded on one side of the straight core, for mounting the circuit board and the insulating layer; the straight core further having a winding, wound around each tee, having the insulating layer formed thereon; the straight core still further having a covering, which together with another portion of the insulating layer, are pre-molded on one side of the back yoke of the straight core, and a plurality of binding pins projecting from the covering, for connecting the winding wound on each tee; the stator being formed by bending the straight core at the V-shaped cuts, into an arcuate or annular shape, and joining opposite ends of the back yokes to each other by welding or adhesion, such that the winding on each tee is wired and connected to other of the windings; the motor frame being molded as a single body around a longitudinal axis of the stator mounting the wiring circuit board thereon, and entirely covering the stator, except for an inside diametrical portion thereof; and wherein said molded motor is a brushless DC motor.
