Abstract

1,018,660. Dynamo-electric machines core construction. A. W. COCHARDT. Dec. 9, 1963 [Dec. 13, 1962], No. 48486/63. Heading H2A. A dynamo-electric machine has a permanent magnet salient pole stator co-operating with a normal wound rotor where each stator pole carries flux produced by two adjacent ferrite magnets each having one similarly poled face in contact with the frame and the other face in contact with a pole shoe common to both magnets. As shown, frame 20, made of magnetic material, is of square section and has anisotropic ferrite permanent magnets 3, 4, 5, 6 secured inside it. Pole shoes 8, 10, which may be laminated or of sintered construction, are attached to the inner faces of the pairs of magnets either by using glue or by die-casting a lead based alloy around the components. This construction is stated to reduce the leakage flux. Interpoles may be provided between the poles of the machine and the pole shoes may be wound with pole face compensating windings. A four pole machine using a hexagonal frame is also described with the magnets lying along the internal flats, Fig. 3 (not shown). In all modifications the magnets may be magnetized after assembly and the pole shoes longitudinally slotted and a temperature dependent shunt used between the poles to keep the motor speed constant.
