Abstract
401,292. Motors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and SAUNDERS,N.F. T., c/o General Electric Co., Witton, Birmingham. May 2, 1932, No. 12626. [Class 35.] Cores commutators.-A motor, more particularly for gramophone driving, has the field coil disposed about the axis of rotation and between radially extending plates provided at their outer edges with flanges which serve as pole-faces, and the armature, which is outside these pole-faces, has a disc type commutator. In the form shown, the field coil 22 is located on a hub 19 between the plates 14, 15 which respectively have diametrically opposed flanges 16, 17 subtending about 165 degrees and this stator system is fixed to an aluminium support 1. The lower plate 8 carries a ring armature 7 and a commutator 24 consisting of a plurality of segments 26 held in a trough 27 by moulded insulation and by projections 29 formed on this trough. In a modified form, each stator plate may have a subdivided flange forming projections interleaving with corresponding projections on the other plate, and the armature may be wave wound, the coils being located in slots in the inner periphery of the core. The cuts in the flange of the stator plates may be at an angle to the motor axis, and the commutator construction may be as described in Specification 401,289. The motor may be used on alternating or continuous-current.
