Abstract

An electrical machine may include a rotor rotatable about an axis of rotation which defines an axial direction, a stator including a plurality of stator windings, a coolant collector chamber, and a coolant distributor chamber fluidically communicating with the coolant collector chamber via at least one cooling duct. At least one stator winding may be embedded into a plastic compound composed of an electrically insulating plastic. The stator may further include a stator body having a space. The at least one cooling duct may be arranged in the stator body and may be at least partially defined by at least one aperture disposed in the stator body through which the coolant is flowable. The at least one aperture may open towards the space and may be closed in a fluid-tight manner via the plastic compound.
