Title:
STATOR FOR AN ELECTRIC MOTOR, INCLUDING FOR A BRUSHLESS DIRECT CURRENT MOTOR
Document Type and Number:
WIPO Patent Application WO1999014841
Kind Code:
A3
Abstract:
Disclosed is a stator for use in an electric motor, including a brushless direct current motor, which presents a stator body (9) provided with a number of stator teeth (3) for receiving stator coils (W1, W2, W3, W4), said stator body (9) comprising a base body (10) of magnetizable material which has an insulating layer at least in the area of the stator teeth (3) capable of receiving or having received said coils. According to the invention, the insulating layer is designed as a plastic layer connected to a base body by plastic injections, and a supporting element (13) of the stator body (9), intended for wrap type contacts (15) to which the coil ends are linked, is injected so as to form one piece with the insulating layer.
