Abstract:
An electric machine, for example for a motor vehicle, is disclosed. The electric machine includes a rotor rotatable about an axis of rotation that defines an axial direction of the electric machine, and a stator including stator windings. A coolant distributor chamber and a coolant collector chamber are provided, and arranged with an axial spacing to one another. The coolant distributor chamber fluidically communicates with the coolant collector chamber for cooling the stator windings via at least one cooling channel that can be flowed through by a coolant. At least one of the stator windings is embedded into a plastics compound composed of an electrically insulating plastic for thermal coupling.
