Abstract
The invention relates to a stator arrangement for an electric machine having a stator ring that is closed at its inside circumference and has stator poles at its outside circumference, wherein the stator ring is built up of a plurality of substantially identical T-shaped segments and wherein each of the T-shaped segments has a main leg having a head and a base and two arms protruding sideways from the head of the main leg, the main legs of the T-shaped segments are aligned in a radial direction and the T-shaped segments are arranged adjacent to each other with alternating orientation of the head and base of the main leg such that they complement one another to form the stator ring.
Claims11
A stator arrangement for an electric machine having a stator ring (10) that is closed at its inside circumference and has stator poles at its outside circumference,
- wherein the stator ring (10) is built up of a plurality of substantially identical T-shaped segments (12, 14) and wherein
- each of the T-shaped segments (12, 14) has a main leg (16) having a head (20) and a base (18) and two arms (22, 24) protruding sideways from the head of the main leg, the main legs (16) of the T-shaped segments (12, 14) are aligned in a radial direction and
- the T-shaped segments (12, 14) are arranged adjacent to each other with alternating orientation of the head (20) and base (18) of the main leg such that they complement one another to form the stator ring (10).
A method for the manufacture of a stator arrangement according to one of the preceding claims wherein a phase winding (28, 30) is applied to every second (12) T-shaped segment (12, 14), the T-shaped segments (12, 14) are arranged adjacent to each other with alternating orientation of the head and base of the main leg in such a way that in the case of the T-shaped segments (12) that carry the phase windings (28, 30), the head of the main leg is oriented radially outwards and in the case of the other T-shaped segments (14) the head of the main leg is oriented radially inwards.
