Apparatus for an electric machine

An apparatus for an electric machine comprises: a stator with at least one stator tooth (213-1813), which ends at an axial end of the stator tooth in a first axial position (321-1721); an electrical conductor (926, 1026) extending in a first axial region (ab1) extending from the first axial position (321-1721) to within the stator tooth (213-1813) suffices, adjacent extends in the axial direction of the stator and extends out in a second axial region (ab2), which from the first axial position (321 to 1721) to outside of the stator tooth (213-1813), at least in part a winding head (323-1823) forms; a rotor having at least one permanent magnet (219-1819), wherein the rotor relative to the stator about an axis extending in the axial direction of the rotational axis at a first axial distance between the stator and the rotor and at a second axial distance (d2) between the stator and rotatably to the rotor, wherein at least one of the following feature groups a, B is realized: (a) located entirely the electrical conductor (926, 1026) is in the first axial region (ab1) in a first radial region (RB1); the electrical conductor (926, 1026) is in the second axial region (ab2) in a second radial region (RB2) is arranged which comprises at least a portion of the radial portion (TRB) which does not overlap with the first radial region (RB1), wherein the portion of the radial portion (trb ) is disposed radially further away from the rotor than the first radial region (RB1); (B): the apparatus further comprises a co-rotating with the rotor rotor yoke structure (1239 to 1839) which axially outside the permanent magnets (219-1819) is arranged when the second axial distance (d2) is taken.
