ABSTRACT:
In an induction machine having power windings disposed coaxially about the iron core thereof, means for reducing an axial mechanical force produced in any given winding by the interaction of the radial components of leakage flux produced at a time of short-circuiting and an electric current flowing in the given winding at that time. The reducing means includes a plurality of loops mounted respectively at the ends of the given winding and adapted to link the radial components of leakage flux produced at the ends of the given winding at the short-circuiting to generate induced currents in said loops. These currents produce magnetic flux for cancelling the radial components of leakage flux, respectively. In order to equalize the quantities of the radial flux components having the given winding to each other to reduce the axial force, a pair of search coils are mounted at the ends of the given winding so as to link the radial flux components, respectively and then the windings are axially relatively moved till the difference between the electromotive forces induced in the search coils becomes zero.
