<p>1,003,497. Dynamo-electric machines. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. Sept. 10, 1963 [Sept. 11, 1962], No. 35666/63. Heading H2A. In an electrical rotating machine, e.g. motor, having at least one magnetic field-creating stator member co-operating through a short air-gap with a hollow cylindrical rotor member the latter encloses a magnetic member free to rotate independently of the rotor member and one of the members has at least one winding formed of flat thin conductors bonded to the faces of a thin insulating carrier by a printed circuit technique. In the cylindrical air - gap machine shown in Figs. 1 and 2, the stator comprises casing plates 11, 12 supporting struts 10 within which are supported equispaced alternatepolarity field magnets 8, 9 and brushes 15 which engage the wave or lap winding 16 . . . 22 printed on the two faces of a carrier longitudinally stretched between annular end supports 2, 3 secured to a shaft 4 rotatable in bearings 13, 14; the magnetic member 5, mounted on bearings 6, 7 completes the magnetic flux path. In Fig. 3, a stationary printed winding 41 forms the field and the rotor is a thin copper cylinder 31 stretched between the end discs 2, 3, and in both embodiments the member 5 may have permanent magnet poles in which case it will freely rotate. In the flat air-gap machine shown in Fig. 5 the stator comprises rings of permanent magnets 58, 59 or coercive ferrite between which are two electrically-independent printed circuit winding discs 61, 62 glued to a ring 62 engaged by brushes 63 and enclosing a freely rotatable ring 55 of either soft iron or ferrite which may be magnetized. Alternatively the Fig. 5 machine may be constructed as a Fig. 3 counterpart, having printed circuit stator field windings and a twin copper disc rotor. Specifications 874,394 and 902 295 are referred to.</p> |
