description A method for smoothing the torque characteristics of a multi-phase PM synchronous machine by controlled driving with a conventional voltage source inverter operated in accordance with a predetermined switching sequence wherein the sum of the excitation voltages applied to the incoming phase winding and outgoing phase winding are maintained constant at a predetermined value for the duration of each commutation period. In addition, the individual excitation voltages applied to the remaining phase active windings are also held constant during the commutation period.
