Abstract
A method for producing a stator for an electrical machine includes providing the stator including a ring-shaped stator body, from which a plurality of stator teeth arranged spaced apart along a circumferential direction of the stator body protrude radially to the inside. A space is thereby provided between two stator teeth adjacent to one another in the circumferential direction. Second, a first injection molding of two stator teeth adjacent to one another in the circumferential direction with a plastic is performed. Third, a stator winding is arranged in the space. Fourth, a second injection molding of the stator winding arranged in the space with the plastic is performed such that an air gap and/or an air trap between the stator teeth injection molded in the second step and the stator winding after the arrangement of the stator winding in the space in the third step, is filled with the plastic.
