Claim 0:
1. A method for producing an electric motor having a coil, comprising the steps of:
providing a coil core, wherein the coil core has a slot which extends in a longitudinal direction of the coil core;
introducing a slot insulation into the slot such that the slot insulation projects beyond the coil core in the longitudinal direction and forms a projection;
retaining the slot insulation in the slot by circumferentially introducing a squeezing force to the projection during introducing of a first layer of a conductor material into the slot;
pressing the first layer of the conductor material and the slot insulation together by a force in a region of the projection such that a force-fit between the first layer of the conductor material and the slot insulation in the region of the projection is produced which force-fit fixes the slot insulation in the longitudinal direction; and
during the step of pressing the first layer of the conductor material and the slot insulation together by the force in the region of the projection such that the force-fit between the first layer of the conductor material and the slot insulation in the region of the projection is produced, introducing a second layer of the conductor material into the slot.
