Abstract :
The design of equalizer windings for DC machines is generally of an empirical nature. This paper presents an analytical technique for the design of equalizer windings. Use is made of a modern computer-aided analysis and design tool called finite-element analysis and machine circuit theory. The analysis is limited to simplex lap-wound DC machines, but should equally well apply to multiplex windings. The technique was successfully applied to a 4.1 MW DC generator. The generator´s equalizer windings burned out, after the machine was rebuilt due to a mechanical failure
