Abstract
An active part of an electric machine includes at least two teeth, each having a magnetically permeable material and protruding from a lateral surface of the active part in a radial direction. Each tooth has an open recess in a plane spanned by a substantially radial direction and a direction substantially along an axis of rotation. A winding groove is arranged between the two teeth substantially along an axis of rotation of the active part for receiving an electrical winding. Arranged at least partially in the open recess is a thermally conductive element having a thermally conductive material with a thermal conductivity which is greater than a thermal conductivity of the magnetically permeable material.
