Abstract :
This paper designs a universal flux-weakening loop which enables the realization of the maximum speed in both cases: when the center of the voltage limit circle lies inside and outside of the current limit circle. This flux-weakening loop can be implemented in PMSM traction drives which require frequent switching between maximum power and continuous power modes by changing the current limit. Simulation results are shown to validate the effectiveness of the proposed universal flux-weakening loop.
