Abstract

An electric motor having has a rotor and a stator with a stator core as well as an insulation assembly, which extend along a common longitudinal axis from a first end face to a second end face of the stator. The stator core is formed with bars arranged uniformly distributed on the circumference to accommodate conducting wires wound into coils. The insulation assembly has a first insulation element, second insulation elements, and a third insulation element. The first insulation element is arranged between conducting wires and the stator core; a respective second insulation element is arranged in an intermediate space formed between coils arranged to fit closely to one another; and the third insulation element is arranged on an inner side of the stator, the inner side pointing inward in the radial direction, in a manner so as to seal the inner side.
