An electric machine includes a housing having cylindrical outer walls including a stator portion and a cooling system portion adjacent to the stator portion. The electric machine includes a rotor drive shaft protruding coaxially with the cylindrical outer walls of the electric machine from the front of the electric machine, and a rotor coupled to the rotor drive shaft and arranged coaxially within the stator portion of the cylindrical outer walls of the machine housing. At least one air inlet is formed in the cylindrical outer walls of the machine housing between the stator portion and the cooling system portion. At least one air guide vane extends from the air inlet into a hollow volume of the rotor forming a cooling air duct from the air inlet past the inner surface of the rotor and back to the inner surface of the cooling system portion.
