Abstract:
Described are, among other things, an electric machine (10) and a housing (12) for an electric machine. The electric machine (10) is provided with a liquid cooling arrangement and comprises a housing (12). The housing (12) is formed as one unitary element and comprises a first space (30) in which first space (30) a stator (21) and a rotor (23) are located. The rotor (23) has a shaft (20). Further, a second space (50) is formed in the housing (12). In the second space (50) electronics (54) for operation of the electric machine is located. Also, a third space (40) is formed in the housing (12), the third space (40) is located, seen in axial direction of the shaft (20), between the first space (30) and the second space (50). The third space (40) comprises at least one inlet (18) for a cooling liquid and at least one outlet (28) for the cooling liquid.
