Title:
METHOD FOR PRODUCING ROTATING ELECTRICAL MACHINES
Document Type and Number:
WIPO Patent Application WO/2013/149688
Kind Code:
A3
Abstract:
The invention relates to a method for producing rotating electrical machines, with a motor coil for motors or generators that is produced in a self-supporting manner, wherein the coil already surrounds the inner part during production, i.e. is pre-mounted, and said inner part is also used during coil production as an aid for shaping the coil, wherein in a first step, the motor coil (5) is gradually wound over the magnetic inner part (2) between two end faces (4, 4') completely surrounding said inner part (2), and in a second step, the motor coil (5) is shaped by pressing the coil wires by moving the shaft (1) with the surface of the inner part (2) against the inner side of the motor coil (5), particularly rolling it eccentrically over said inner side and pressing the coil against an abutment (7), and in a third step the pressed motor coil (5) is baked by application of heat. The invention also relates to a rotating electrical machine.
