Abstract

See full text

An electric machine includes a rotor rotatable about a rotational axis, by which an axial direction is defined, and a stator with stator windings, a coolant distributor space and a coolant collector space. The coolant distributor space communicates fluidically with the coolant collector space to cool the stator windings with a cooling duct. The stator includes stator teeth supporting the stator windings and protruding radially inward from a stator body of the stator. A stator groove is formed between two stator teeth which has a radially outer groove zone extending radially inward away from the stator body into a radially inner groove zone, the radially inner zone width of which is smaller than the radially outer zone width, when measured along the circumferential direction, of the radially outer groove zone. At least one stator winding is embedded, for thermal coupling, into an electrically insulating plastic arranged in the stator groove.
