Abstract

An electric machine arrangement for a motor vehicle drivetrain, having a machine housing which can be fixed to a drivetrain housing, a stator which is fixed relative to the machine housing, a rotor which is mounted, concentrically with respect to the stator, within the machine housing and which has a rotor axis, wherein an air gap is defined between the stator and the rotor. Here, the rotor has a rotary bearing section which is mounted, with a radial clearance, rotatably relative to a housing bearing section of the machine housing, wherein the radial clearance is smaller than the air gap.
