A new design for electrical machines and generators involves introducing additional windings in the stator of a machine which drive flux in complete loops around the back of the stator core drawing the stator core into use as an inductor or transformer as well as a conductor of flux for the main working flux of the machine. The stator core may be divided into several different lengths each of which behaves as an independent flux carrier. The inductor or transformer so produced has numerous possible applications including filtering the current in the DC link of a drive to suppress zero-sequence components of voltage at the terminals of the machine, suppressing certain combinations of phase currents in the machine and enabling the machine to present several different voltage-to-current ratios to its supply. |
