    摘要： A process for producing resin bonded magnet structures is disclosed which includes the steps of: (a) adding a solid epoxy resin of at least one epoxy oligomer and a microcapsule which contains at least one liquid epoxy resin to a melt spun powder of a rare earth element-iron alloy to form a granulated intermediate material, wherein the epoxy oligomer has alcoholic hydroxyl groups in the molecular chain thereof and the solid epoxy resin has a softening temperature (Durran's melting point) of 65.degree. C. to 85.degree. C.; (b) mixing the granulated intermediate material with a powdered curing agent and a lubricant to form a compound; (c) forming a green body of a resin bonded magnet by compressing the compound, and then integrating the green body directly with a supporting member; and (d) curing the solid and liquid epoxy resins in the green body by application of heat to form a rigid structure of the resin bonded magnet integrated with the supporting member.

    摘要： A motor includes a stator integrally molded together with a stator member, which includes a stator iron-core wound with a winding, by insulating resin, a rotor mounted on a shaft as a center and confronting the stator, two bearings supporting the shaft rotatably, brackets fixing the bearings, and a drive circuit board including a drive circuit which supplies an electric current to the winding and drives the rotor. Either one of the two bearings includes an outer ring and an inner ring both of which are electrically insulated from each other.
