Encoder system () for a drive, including a revolution counter having a Wiegand sensor () which is disposed on a stationary part () of the encoder system (), and at least two pairs of magnets which in the revolving direction () are disposed at different positions on a rotatable part () of the encoder system (), wherein the pairs of magnets comprise in each case a first magnet () and a second magnet (); and a position encoder having a magnetic field sensor () which is disposed on the stationary part (), and a magnetic strip () which is disposed on the rotatable part (); wherein, in each pair of magnets, the first magnet (), the magnetic strip () of the position encoder, and the second magnet () in terms of a first direction are disposed in this sequence on the rotatable part ().

Encoder system for a drive

The winding (W) comprises at least two poles and at least one phase, with which the poles are wound. The phase comprises at least two parallel-wired winding branches (WA,WB,WC,WD). At least two of the winding branches (WA,WB) are different from each other in the winding of at least one of the poles (P). At least one pole (P) is wound from at least two winding branches (WB,WC,WD). At least one of the winding branches (WA,WB,WC,WD) is included in the winding of at least two poles. The poles are wound with the winding branches (WA,WB,WC,WD) in the sense of an essentially symmetrical current loading of the phase.
