Abstract
An electric traction machine for a motor vehicle includes a rotor, a stator, a stator sleeve into which the stator is pressed, and a housing. The housing, together with which the stator sleeve, delimits at least one pressurized oil cooling channel and at least one water cooling channel, wherein an equalization chamber is kept free axially between the at least one pressurized oil cooling channel and the water cooling channel closest thereto, which equalization chamber is configured to collect oil that has leaked out of the pressurized oil cooling channel.
