Claim:
1. A multiphase motor generator system, comprising: a multiphase induction motor having a plurality of separate terminals; a multiphase inverter coupled to a DC link voltage source and the plurality of terminals of the multiphase induction motor; a plurality of current detectors configured to detect a plurality of currents that flow between the multiphase inverter and the plurality of terminals of the multiphase induction motor; and a controller coupled to the current detectors and the multiphase inverter, and configured to receive the detected currents and output a plurality of control voltages to the multiphase inverter, the controller including: wherein the multiphase induction motor is an n-phase induction motor, with n being an integer that is multiple of 3, the multiphase to dq conversion unit being configured to:  where P represents the number of poles generated in the multiphase induction motor; and  where θ=θ
