摘要： 1455338 Dynamo-electric machines ROBERT BOSCH GmbH 1 March 1974 [2 March 1973] 9273/74 Heading H2A A six pole D.C. motor comprises a stator having main poles and interpoles, and an armature including a wave winding in which two coil sides are arranged side by side in each layer in each slot, e.g. slot 2, Fig. 5, and wherein coils having respective coil sides in one and the same layer in each slot are respectively under- and over-pitched by a fraction of a slot, their other coil sides being therefore in different slots, e.g. slots 9, 10. The motor is intended for use as a traction motor and the pole member and winding arrangement chosen are stated to permit a high power/weight ratio and to facilitate commutation. The armature windings 18, Fig. 1, is mounted on a core 17 secured to a light metal, e.g. aluminium, spider 13. The armature conductors may be sub-divided bar conductors. To facilitate commutation, the stator main pole shoes 30, Fig. 4 (not shown) are shaped so that the air gap under each main pole increases in both circumferential directions from the pole centre line.

摘要： To permit light-weight construction with maximum efficiency, the d-c motor is a separately excited six-pole motor having a stepped, or split wave armature winding which is precisely symmetrically arranged on the armature, the armature itself forming a lamination package located on an armature carrier, for example of light-weight metal, for instance of aluminum, in wheel-type arrangement. The armature conductors are superimposed flat strips, the conductors of different windings being located adjacent each other in the armature slots, outer conductors of the armature being welded together, and, in turn, brazed or hard-soldered to the bottom conductor, and then to the commutator, to permit assembly without damage to surrounding insulation.

摘要： This invention relates to an improved armature for a four pole wave wound direct current machine and also to a method for winding the armature for such a machine. A plural turn winding is free formed or wound in place to substantially a final shape with two ends spaced for connection to commutator segments spaced substantially 180.degree. apart on the armature and with at least four sides defining at least two open turns. The winding sides are spaced for engaging slots in the armature core which are spaced substantially 90.degree. apart. The winding is initially free formed and the turns are separated as necessary to insert the winding on the core and to position the winding sides in their assigned slots in the armature core.
