Abstract
1446745 Core constructions VORTEXPUMPEN AG 28 Nov 1973 [28 Nov 1972] 55202/73 Heading H2A The stator of a rotary electric motor has a plurality of radial teeth lying substantially parallel to the axis of rotation, a core magnetically interconnecting the teeth and a number of coils arranged around the core lying in radial planes generally parallel to the axis of rotation and covering the axis ends of the core. In one embodiment (Figs. 1a, 1b) a two-phase double rotor 6, 6<SP>1</SP> motor has a laminated stator core 2 and two sets of coils 3, 3<SP>1</SP> and 4, 4<SP>11</SP> which are parallel to the axis of rotation and generally perpendicular to each other. The rotors 6, 6<SP>1</SP> are composed of iron caps with slots containing aluminium or copper conductor-bars 7 connected together at each end by shorting rings 8, 8<SP>1</SP>. The complete conductor arrangement 7, 8, 8<SP>1</SP> may be pressure diecast. In other embodiments, the stator is made dumbell shaped (Fig. 2, not shown) or frusto-conically shaped (Fig. 3, not shown) and in a modification, the circumferentially outermost parts 1 of the teeth are made shorter than the innermost parts 1<SP>1</SP> enabling greater width between the radially inner ends of adjacent teeth. The coil arrangement is said to provide lighter coils thereby reducing copper losses.
