Method for the manufacture of stator-or-rotor-windings for electrical machines from parallel-wires

#1. Field of the Invention

#The present invention relates to a method and device for manufacturing of stator or rotor coils for electrical machines from parallel wires. More specifically, the present invention relates to winding a group of coils on a jig by rotating the jig, and drawing the parallel wires from a stationary feeding device located in a peripheral direction with respect to the jig. When wound, the completed group of coils can be transferred to a coil receiver and a device for the manufacture of stator or rotor windings for electrical machines. The rotating jig is provided with a drive as well as a fixed wire rod guide and a coil receiver in a peripheral direction with respect to the jig.

#2. Discussion of the Related Art

#The above and still further objects, features and advantages of the present invention will become apparent upon consideration of the following detailed description of a specific embodiment thereof, especially when taken in conjunction with the accompanying drawings wherein like reference numerals in the various figures are utilized to designate like components, and wherein:

#FIG. 1 is a side view of the device for manufacturing windings according to the present invention;

#FIG. 2 is a side view of a jig; and

#FIG. 1 shows a winding device 1 having a basically U-shaped stand 10. The left leg of stand 10 has a jig 12 attached thereto and the right leg 13 has a coil receiver 14 attached thereto. The jig 12 on the left leg is pivoted and can slide axially. The jig 12 also has a pick-off device 16.

#Within the range of the axial length of the jig 12, a shifting unit 18 is provided, which can travel by means of a motor 20 along the jig 12, so that parallel wires 19 can be guided via supply drums or coils (not shown) through the shifting unit 18 to the jig 12, while the jig 12 rotates. The shifting unit 18 is stationary and is disposed in the peripheral direction with respect to the jig 12. Thus, when the jig 12 rotates, the parallel wires 19 will be extracted from the shifting unit 18.

#The jig 12 is driven by an additional motor 22, which also drives the coil receiver 14 and is transmitted through a linkage 24 which is guided in a housing 10. The transmission between the motor 22 and the jig 12 or between the motor 22 and the coil receiver 14 is selected in such a way that the coil receiver 14 rotates with the jig 12 with the same rotating speed and the same direction. A clutch device 23 is disposed between the motor 22 and the coil receiver 14, so that, the connection therebetween can be interrupted. The jig 12 can also be driven without the simultaneous rotation of the coil receiver 14.
