ABSTRACT:
A stator yoke for a DC brushless motor is comprised of a layer of insulating material of a predetermined thickness and a layer of magnetically permeable material which are bonded to each other by adhesive or the like. The magnetically permeable layer can be composed of several steel plates, preferably of silicon steel, bonded to each other. The insulating layer in one embodiment is composed of a cloth-like material, for example, of glass fibers, and a cured adhesive filling the interstices of the cloth-like material and bonding the insulating layer to the magnetically permeable layer.
