Abstract
This paper present a generalized mathematical model for calculating equivalent resistance of the
conductive route in order reducing the level of heat losses in the yoke laminations of collector system with additional
junction used it is used in the transformers provided with rotating secondary winding. The heat losses at issue is due
to induction currents established in the circuits consisting of yoke laminations pairs of shorted by collectors elements.
