Abstract
A method for adding or removing a rotor having at least one permanent magnet of a permanently excited synchronous machine in a motor vehicle, which also includes a stator having one or more stator windings, wherein the permanently excited synchronous machine and a pulse inverter connected to the one or more stator windings form a motor arrangement, wherein upon adding or removing the rotor the stator windings are energized for generating a stator field acting against the permanent magnetic field generated by the permanent magnet of the rotor by the pulse inverter in a maintenance mode, such that the forces occurring between the stator and the rotor are reduced and/or at least partly canceled.
