Electrical rotating machines operate through the interaction of electrical currents with magnetic flux that may itself be created through other electrical currents. In both cases the magnetic flux present in the air gap of the machine is a crucial component of its overall performance dictating, among other things, torque (and hence machine size) and noise and vibration. Both these particular aspects are of prime importance to designers of electrical propulsion motors for naval applications. The prime aspect of the magnetic flux in the air gap is its shape or profile which has a direct bearing on both torque density and torque pulsations. This paper describes a method to analyse a machine winding through application of Fourier Series to determine the efficacy of the winding with regard to machine excitation. The method is first explained by analysing a conventional winding and then applied to a Fractional Slot Winding and a Dual Winding. |
