Abstract

The excitation is performed in a brushless a.c. generator having a single or poly-phase main winding by providing an auxiliary winding having phases (a1 a2; b b2) corresponding to only two phases of an open delta winding, the two auxiliary winding phases (a1 a2; b1 b2) being connected together at one end (a2 and b1) of each of the phases thereof and providing, in use, between their outer ends (a1, b2), that is the ends which are not connected together, a power supply for producing the exciter field of the generator. Alternatively the auxiliary winding may be an electrically equivalent concentric winding. <IMAGE>
