1. An electric motor comprising:
a rotor and a stator, the rotor and/or the stator has a multiplicity of teeth;
a first winding space, for receiving a multiplicity of coil windings wound from a winding wire, is formed between two respective immediately adjacent teeth;
a second winding space, connected to the respective first winding space to receive at least one wire portion of the winding wire, is formed adjacent to at least one first winding space;
the second winding space has two mutually opposing side walls in a circumferential direction about an axis of rotation of the rotor that are spaced apart from one another by a first distance on a first side of the second winding space facing in the radial direction toward the first winding space;
a second distance on a second side of the second winding space facing away from the first winding space in the radial direction;
a third distance in a center portion between the first side and the second side in the circumferential direction;
the second distance is equal to or greater than the first distance, and the third distance is greater than the second distance; and
two receiving pockets, situated opposite one another in the circumferential direction, are formed in the center portion of the side walls in order to respectively receive the at least one wire portion of the winding wire.
