Embodiment Construction

[0071] figure 1 is perpendicular to the axis of rotation, the electric motor 5 is shown in cross section with the stator 1 and the rotor 2 surrounded by the stator 1 . The stator 1 comprises a plurality of slots 8 along its circumference, which are separated from each other by stator teeth 6 (cf. Figure 3-4 ). In the present invention, the motor takes the form of a rotating field machine with 3 phases and 6 poles. Altogether, in this example, the windings are distributed over 54 slots. Thus, 9 slots 8 are provided per pole. Two shaped strips 3, 4 insulated from each other are located in each case in each groove 8 ( Figure 3-4 ). The profiled bar 4 facing the rotor 2 forms an upper, also called upper profiled bar. The shaped bars 3 located deeper in the groove 8 and away from the rotor 2 form the bottom layer and are called bottom layer shaped bars.

Abstract

Stators (1) for electrical machines, in particular a rotating field machine, such as a motor or generator, in particular for an electric vehicle, wherein a stator (1) has slots separated by stator teeth, into which shaped bars (3, 4), formed from a plurality of individual wires (10), are deployed, characterised in that in each case the two sidewalls of a stator tooth bounding adjacent slots in the region of the shaped bars (3, 4) run essentially parallel to one another.

Description

[0001] This application claims the benefit of priority of an earlier U.S. provisional application no. 61 / 663,447, filed June 22, 2012, as its non-provisional application, which also claims the earlier European application, filed June 22, 2012 The benefit of priority of no. EP12173166, as described herein, is hereby expressly incorporated by reference in its entirety in European application no. EP12173166 and US application no. 61 / 663,447 for all intents and purposes. technical field [0002] The present invention relates to a stator of an electrical machine, in particular a rotating field machine such as a motor or a generator, in particular a stator for an electric vehicle, wherein the The stator has along its circumference a plurality of slots separated by stator teeth, within which slots are arranged shaped bars formed by a plurality of individual cables. The invention also relates to an electrical motor having such a stator and a method for manufacturing the stator. Back...
