Abstract
Official abstract text for this publication.
A rotor position encoder ( 01 ) for an electronically commutated electric machine ( 02 ) having a stator and a rotor ( 03 ) and including a rotor position sensor ( 05 ) which is mounted on the stator so as to rotate therewith and has the purpose of detecting the rotational position of the rotor ( 03 ) with respect to the magnetic field of the stator, and a signal encoder ( 07 ) which is mounted on the rotor ( 03 ) so as to rotate therewith. The rotor position encoder is defined in that it has a reference encoder ( 08 ) for detecting reference values of the magnetic flux density of the rotor field, wherein the reference values ( 09 ) serve to determine an angular offset ( 11 ) between the signal encoder ( 07 ) and the position of the rotor ( 03 ). Furthermore, a method for determining an angular offset ( 11 ) between a signal encoder ( 07 ) of a rotor position encoder ( 01 ) and a rotor position of an electronically commutated electric machine ( 02 ) is provided.
