Abstract
The invention relates to a stator (1) for an electric drive motor having a number of stator teeth separated by grooves, wherein the stator teeth are wound by a multi-strand winding, and wherein one strand comprises several coils (5, 6), and wherein individual coils (5) each comprise multiple stator teeth, and preferably multiple stator teeth are combined at the height of their tooth necks into a collective stator tooth (4) having a tooth base (3) and multiple tooth heads (2), characterized in that two stator teeth each are combined into a collective stator tooth (4).
Claims15
A stator (1) for an electric drive motor having a number of stator teeth which are separated by slots, with a multiple-section winding being wound around stator teeth and with one section comprising a plurality of coils (5, 6) and with individual coils (5, 6) each surrounding a plurality or stator teeth, and with a plurality of stator teeth preferably being combined at the level of their tooth neck to form one combined stator tooth (4) with one tooth foot (3) and a plurality of tooth heads (2), characterized in that two stator teeth are in each case combined to form one combined stator tooth (4), wherein the number of turns of the coils (6) around the tooth feet (3) and the number of turns of the coils (5) around the tooth heads (2) result in a similar flux linkage.
