This paper presents a maximum efficiency algorithm (MEA), aiming at minimizing both copper loss and iron loss, for the interior permanent magnet synchronous motor (IPMSM) drive system. The equivalent circuit model is utilized to reach the optimal dq‐current function with the optimal process. Besides, the current–voltage limitation algorithm for the MEA is proposed to solve the current limitation and the voltage limitation issues. The feasible region for the MEA is the intersection of the maximum current region and the maximum voltage region. With the IPMSM test platform, the validated experiments and efficiency tests were implemented to evaluate the proposed strategy. The experiments indicate the MEA operation is effective and feasible to improve the efficiency of the IPMSM. Besides, the feasible operating region of the IPMSM can be extended by the MEA. With the advantage of improving efficiency and extending the operating region, the MEA is suitable for applying the IPMSM drive system.
