  • Patent number: 6603234
    Abstract: In a method for producing a winding for electrical machines, a plurality of conductor elements are fitted on a winding former or stator tooth. The conductor elements are aligned parallel to one another in a predetermined order and are placed alongside one another in a slot while being fitted onto the winding former, with the predetermined order being reversed at least once while being fitted, so that the elements change their position on the winding former, at least in places. The winding process is carried out by machine, with the winding former being rotated under a number of wire guide nozzles, the wire guide nozzles being rotated through 180° as a group after a defined number of turns.

  • Patent number: 6541888
    Abstract: A winding body has a winding area (31) for a winding (13), which winding area (31) is formed by a winding carrier (32) and two legs (34, 35) which define the winding area (31) in axial direction (L) and are connected with the winding carrier (32). The winding carrier (32) has a locking device (40) for locking the winding body (30) at a winding tooth (24). Further, a temperature sensor (50) for measuring the temperature in a coil (25) can be provided in the winding body (30). The winding body (30) has a receiving area (36) for a connection device (70) for the windings (13), wherein the receiving area (36) is formed by one of the legs (35), an elongation area (33) of the winding carrier (32) extending beyond this leg (35), and a fixing leg (60) at a distance from the leg (35).

  • Publication number: 20020180577
    Abstract: A winding body has a winding area for receiving a winding, which winding area is formed by a winding carrier and two legs which define the winding area in axial direction and are connected with the winding carrier. A temperature sensor for measuring the temperature in the winding is arranged in the area of the winding carrier.

  • Patent number: 6369473
    Abstract: A stator for an electrical machine includes a stator yoke and a plurality of stator coils arranged on the stator yoke. An interconnection arrangement is arranged on one end face of the stator yoke. The interconnection arrangement has connecting conductors which are electrically insulated from one another. The connecting conductors are arranged concentrically with respect to one another and each have a different diameter. The connecting conductors have connections for the ends of the stator coils and for connection to the electrical machine. To minimize the space requirement of the stator and simultaneously allow the stator coils to be automatically interconnected in an automated manner, the interconnection arrangement is arranged inside an area bounded by the stator coils. Furthermore, the connections for the ends of the stator coils include connection projections designed such that they project outward at an angle to the respective connecting conductor to attach the stator coil ends.
