Abstract

An electrical machine for a vehicle may include a rotor, a stator, a coolant distributor chamber and a coolant collector chamber. The rotor may be configured to be rotated about an axis of rotation defining an axial direction of the electrical machine. The stator may include a plurality of stator windings. The coolant collector chamber may be axially arranged at a distance from the coolant distributor chamber. The coolant distributor chamber may be configured to communicate fluidically with the coolant collector chamber by at least one cooling channel through which a coolant can flow. At least one of the stator windings may be embedded in at least one plastic mass consisting of an electrically insulating plastic for thermal coupling to the coolant. At least one of the coolant distributor chamber and the coolant collector chamber may be arranged at least partially in the at least one plastic mass.
