This paper proposes a novel approach to modelling the torque/speed envelope of PMSMs which considers harmonic components in the voltage waveform. The proposed model is computationally efficient and can produce precise results rapidly, the accuracy of the model and improvement over previous dq based techniques is validated against experimental measurements of a 21-slot 14-pole IPM motor for a hybrid electric vehicle. The technique is then applied to a model of a ferrite based PMSM for a 48V application; it is shown how use of the dq method here can give a significant over estimation of the available peak power when compared to the Fourier approach.
