electric motor and electric drive unit for a motor

Electric drive unit for a motor vehicle which has an electric motor, the electric motor comprises: (a) a stator (20) with pole windings; (B) a rotor (10), (c) existing between the stator (20) and the rotor (10) an air gap (24); (D) and the characteristic that, in that region of the posterior circumference of the stator which is situated away from the gap (24), small tubes are present (90), preferably of metal, which can be traversed by the coolant for cooling liquid of the stator (20), the drive unit (2) further comprising: (a1) a motor housing (28) fixedly mounted in rotation; (B1) the stator (20) is fixed in the motor housing (28), (c1) the rotor (10) is arranged inside the stator (20), the gap (24) being present between the pole faces of the stator ( 20) and the outer circumference of the rotor (10) directed towards the pole surfaces of the stator (20); (D1) a planetary gear (42) with a sun wheel (52), a planet carrier (44), planet wheels (48) and a crown (56), (e1) the rotor (10) being in connection and the sun wheel (52) of the planetary gear (44) for transmission of torque; (F1) a housing gear (34) of the planetary gear (42), the gear housing (34) being fixed in the motor housing (28) or is - at least in part-a integral element of the motor housing (28), and (g1) a connector member (92) for electrical connection and coolant automotive.
