Abstract :
The evaluation of the eddy current loss and the self and mutual inductances of the commutating coils of a DC machine, armature winding for railway traction by a two-dimensional PC-based finite-element commercial code is addressed. The comparison among several distribution of the conductors occupying a given slot and among slots with different ratio of depth to width is made in order to determine, for a given DC machine, the best design solution with reference to both the loss and the self and mutual inductances of the commutating coils.
