Abstract (en)
[origin: WO2019149475A1] The invention relates to a stator apparatus (2) for an electric motor having a plurality of windings (1' to 12') which are provided on a winding carrier (4), are designed for electromotively interacting with a rotor which is mounted such that it can rotate about a centre axis relative to the winding carrier (4), extend parallel in relation to one another and in relation to the centre axis and are arranged along a profile which is in the form of an arc of a circle and are designed such that they can be individually electrically contacted by winding connections of a winding wire, wherein at least two discs and/or annular, electrically conductively designed wiring rings (8u, 8v, 8w) are associated with the windings (1' to 12') such that they are arranged, in a manner electrically insulated from one another, along an axial direction of the centre axis on the winding carrier (4) such that the winding connections with the same electrical connection polarity (U; V; W) of the windings (1' to 12') are connected to the wiring ring (8u, 8v, 8w), which is associated with this connection polarity (U; V; W), for external common contact-connection in a non-releasable manner by means of welding hooks (20) which are integrally formed with the radially inner side of the wiring ring (8u, 8v, 8w), wherein the wiring rings (8u, 8v, 8w) are integrated into a hollow-cylindrical wiring end disc (6), and in that an annular deflection disc (10) with deflection pins (12), which are arranged distributed around the periphery of the inner side of the deflection disc (10), for deflecting the winding wire is provided on the wiring end disc (6) in the axial direction.
