SU1203642A1 - Combined winding for electric machine - Google Patents

Description

The invention relates to coils of combined electric machines and can be applied, for example, in single-machine frequency and phase converters, in cascade combined AC machines, in a ferromagnetic controlled reactor ah, etc.

The purpose of the invention is to expand the scope.
