Abstract
The present invention relates to a stator. In a stator winding arrangement structure of a drive motor in which hairpin segments in a shape of a hairpin, each having two legs, are inserted into a stator core having a plurality of slots, and legs of the hairpin segments positioned opposite to the stator core are bent and joined to circuitry-form a serial coil bundle, a stator winding of the drive motor is composed of three or more phases and each of the phases consists of two or more successively adjacent slots. An arrangement structure of hairpin segments mounted in the stator core having a plurality of slots of a hairpin drive motor according to the present invention is modified to form a parallel circuit, and a coil extending over the same outermost layer is removed. In addition, structural stability and production yield of the hairpin segments may be improved.
