Fast electric machine operating as synchronous motor or as synchronous generator

摘要

The invention relates to electrical engineering. The electric machine which is the subject of the invention is of the type including, on the one hand, a cylindrical shell 1 inside which are mounted a rotor 4 produced in the form of at least two pole systems 5 which are provided with pole horns and are connected together by a magnetic circuit 7, and a stator 9 including at least two lamination stacks 10, and, on the other hand, an energising system 14, and is characterised in that the energising system 14 is installed outside the shell 1, the latter consisting of magneto-conductive zones 2 alternating axially with non-magnetic zones 3, and in that in each magneto-conductive zone 2 is fixed the corresponding stack 10 of the stator 9. The invention finds its most advantageous applications in fast electric motors for driving turbo compressors, high-pressure pumps for fans, and high-speed wire rolling mills. <IMAGE>
