1. A method comprising:
configuring a motor drive system with a motor/generator and a plurality of inverters coupled to the motor/generator;
configuring a plurality of active harmonic planes to generate a torque on each of the active harmonic planes; and
applying a harmonic plane synchronization control mechanism to the plurality of active harmonic planes so that torque components and magnetizing components of currents are controlled in coordination on different active harmonic planes to output a desired torque from the motor/generator.
