Patent ID: 8188628

Claim:
A method for mounting an angle measuring device with a stator and a rotor on an electric motor with a stator and a rotor, said method comprising the steps of: providing a clutch comprising a first clutch half and a second clutch half which are connectable to one another exclusively in the presence of a finite number of relative angular positions with respect to one another; moving the rotor of the electric motor into a defined relative position with respect to the stator of the electric motor; attaching the first clutch half to the rotor of the electric motor; moving the rotor of the angle measuring device into a defined relative position with respect to the stator of the angle measuring device; attaching the second clutch half to the rotor of the angle measuring device; and attaching the stator of the angle measuring device to the stator of the motor whilst at the same time connecting the first clutch half to the second clutch half.
