The primary goal of this article is to find out best current excitation for controlling maximum torque per amp (MTPA) in internal permanent magnet synchronous motors (IPMSM) with non-sinusoidal back emf. The optimum current elation for the mean torque in the IPMSM is presented in this work in closed form. The suggested work seeks to furnish a universal method for choosing the appropriate current for MTPA control for IPMSM used in EV drive train better than operating vector control for current harmonic injection. Hysteresis current control is also taken into account for current injection in IPMSM. Various examples from experimental investigations are shown, including the optimal current, an FFT analysis of the torque and current profile, and a back emf profile that takes into account the first and third order current harmonics. Finally, this investigation claims an efficient MTPA control strategy under specific operating environment employed in energy-efficient EV drive train.
