Electric machine housing and vehicle drive electric machine

The invention relates to an electric machine casing. This is, at least comprising a first housing part (1) for receiving a Elektromaschinenstators and a relatively rotatable to electric machine rotor in each case in the interior of the first housing part (1), and a second housing part (2) for receiving a power electronics module (3) to an exterior of the second housing part (2), which serves for the electrical energization of the Elektromaschinenstators or -rotors. Here, a cooling channel (4), wherein the cooling channel is at least provided, which extends in the first housing part (1) for cooling the Elektromaschinenstators, and in the second housing part (2) extends for cooling the power electronics module (3), (4) is carried out in the region of the second housing part (2) so that it is only partially from the second housing portion (2) enclosed and is only completely enclosed when the power electronic module (3) on the second housing part (3) is arranged. The invention also relates to a vehicle-driving electric machine with such an electric machine casing.
