Abstract

AUXILIARY WINDINGS IN A ROTATING ELECTRICAL MACHINE A stator for a rotating electrical machine is disclosed, the stator comprising main windings (18) for supplying power to a load and auxiliary windings (20) for supplying power to an exciter. The auxiliary windings comprise a first group of windings (24) arranged to couple to a fundamental component of a magnetic flux, and a second group of windings (26) arranged to couple to a third harmonic of the magnetic flux. By providing a first group of windings arranged to couple to a fundamental component of a magnetic flux, and a second group of windings arranged to couple to a third harmonic of the magnetic flux, the auxiliary windings may be at least partially distributed about the stator, which may lead to better utilisation of the slot space.
