The invention concerns a magnetic system for alternating current machines with non-salient poles, especially a dismountable magnetic flux conduit for an electrical machine. The magnetic flux conduit contains a yoke 1 and a toothed zone 2 with grooves 4 to accommodate a winding 5 and with teeth 6. The toothed zone 2 is made from a segment of continuously corrugated band 3, with radial projections directed along the centre axis of the electrical machine. The toothed zone 2 is made from a segment of the continuous corrugated band 3, which segment is constituted of channels 4 joined to each other by shackle- like elements 8, whose length is equal to the length of the magnetic flux conduit and whose cross section perimeter is equal to the minimum width of the continuous corrugated band 3, while every two adjacent channels 4 are turned 180 degrees in relation to each other. The shackle-shaped elements 8 are arranged alternately at the end surfaces of the toothed zone 2, each shackle-shaped element 8 being made from a portion of the continuous corrugated band 3 and configured as a single piece with the adjoining channels 4, and it has a height equal to the height of the toothed zone 2. The invention can be used in electrical machine building. <IMAGE> |
