Abstract

An electrical machine may include a comprise a rotor, a stator, a coolant distributor chamber and a coolant collector chamber. The rotor may be rotated about an axis of rotation that defines an axial direction of the electrical machine. The stator may comprise 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 communicate fluidically with the coolant collector chamber by way of least one cooling channel through which a coolant can flow. The at least one cooling channel and the at least one stator winding may be embedded in a plastic mass consisting of an electrically insulating plastic for thermal coupling to the coolant.
