Small electric motor (miniature electric motor)

摘要

Parts of small electric motors have a complex and thus expensive construction. Thus, for example, the rotors consist of a plurality of parts. It is proposed according to the invention to design both magnetic return path bodies (5, 9) and the hub body (13) integrally, as a soft-magnetic sintered moulding (30/1). Such motors are used, inter alia, as drive motors in single-processing apparatuses such as cassette recorders and video units. <IMAGE>
