Abstract

An electric machine includes a stator, a rotor, a printed circuit board having at least one sensor configured to detect a position of the rotor, and a system configured to arrange the at least one sensor in different positions on the stator relative to the stator.

First claim

1 . An electric machine comprising:
a stator; a rotor; a circuit board including at least one sensor configured to detect a position of the rotor; and a device configured to arrange the at least one sensor in different arrangements on the stator relative to the stator.

2 . The electric machine as claimed in claim 1 , wherein the different arrangements enable the at least one sensor to detect the position of the rotor at different angle offsets with regard to the stator.

3 . The electric machine as claimed in claim 1 , further comprising:
a plurality of fastening structures configured to fix the circuit board to the stator in at least two different arrangements.

4 . The electric machine as claimed in claim 1 , wherein:
the circuit board includes at least two differently arranged receptacles for configured to receive the at least one sensor, and only one part of each corresponding receptacle is provided with the at least one sensor.

5 . The electric machine as claimed in claim 4 , wherein the at least two receptacles are arranged on opposite sides of the circuit board.

6 . The electric machine as claimed in claim 5 , wherein the circuit board is embodied on both sides with conductor tracks that are configured to make electrical contact with the at least one sensor.

7 . The electric machine as claimed in claim 1 , further comprising:
a retaining element configured to fix the circuit board to the stator.

8 . The electric machine as claimed in claim 7 , wherein the retaining element includes a protective cover for an opening of a housing of the electric machine and/or surrounds a component of the electric machine at least in part.

9 . A method for producing an electric machine including a stator, a rotor, a circuit board having at least one sensor configured to detect a position of the rotor, and a device configured to arrange the at least one sensor in different arrangements on the stator relative to the stator, the method comprising:
selecting one of the different arrangements of the at least one sensor, in dependence upon a desired pilot angle; and positioning the at least one sensor in the selected arrangement with the device.
