MOULD MOTOR AND ITS MANUFACTURE

PURPOSE:To improve output characteristic by insulating a winding section of a miniature induction motor core with resin mould and by covering the stator core wound around with windings by means of resin mould to form a motor frame. CONSTITUTION:Poles 4 are jointed ring-shapedly at an internal edge section 16. In the inside diameter of a joint section 5 iron cores 3 equipped with notches 6, the passage for resin mould, are arranged at both ends and stacked poles 4 with independent cores 3 clamped between them are provided with insulating layer respectively to slot sections 12, inside edge sections 16 and both end faces 17 and secured with resin mould. Consequently, the iron core 3 of pole section improves the flow of the resin in moulding between the poles 4 of the pole core 3 internally clamped by the notches 6 and insulates the slot sections 12, inside edge sections 16 and both end face sections 17, while the individual cores 3 are stacked and secured tightly so as to be no bridges electrically.
