In order to connect an angle measuring device to a brushless direct-current motor, a coupling is used, the coupling halves () of which are each attached to the rotor () of the motor and/or the rotor () of the angle measuring device. Instead of using a coupling that is rotationally symmetrical at arbitrary angular positions as in the prior art, a coupling is used in which the coupling halves () can be connected to one another only in a finite number of relative angular positions. An adjustment must be made before the coupling halves () are attached to the respective rotors (). This allows all subsequent adjustment to be omitted, for example, even for maintenance work.

Method for mounting an angle measuring device on an electric motor

The production costs of electrical machines are to be reduced. To this end, it should be possible to use standard transmitters for different axis heights of the electrical machine. The invention therefore provides a transmitter cover for an electrical machine, having a pot-like hood () for mounting on the electrical machine and for covering a transmitter, wherein the hood () has a central axis. The transmitter cover also has a mounting ring () which engages on the hood () in an interlocking manner. As a result, the hood () is pressed against the electrical machine in the axial direction when the mounting ring () is fixed to the electrical machine. This can prevent fastening screws () colliding with other fastening screws on the motor, this possibly being the case when only the hood () is used to cover the transmitter.
