The rise of electric vehicles (EVs) highlights the importance of performance analysis and efficient motor selection, including Induction Motors (IMs). Induction motors provide enhanced efficiency in the flux-weakening region, leading to increased ranges for EVs, and offering robustness and cost-effectiveness compared to permanent magnet synchronous motors (PMSMs). However, it is important to note that IMs experience rotor cage losses at both high and low speeds. Accurate efficiency mapping plays a vital role in facilitating the design of EV motors. Efficiency analysis of dynamic drive cycle operating points is crucial for evaluating vehicle motors. This paper presents a baseline assessment for performance analysis, focusing on enhancing efficiency map accuracy through comprehensive drive cycle analysis using a combination of experiments, analytic modeling, and numerical simulations on a laboratory-scale IM. Analytic and numerical models are created and performance plots are studied for a particular drive cycle covering a wide range of operating points. A dedicated test-rig is set up to examine the transient behavior of the motor during drive cycles, allowing for a thorough analysis of its dynamic performance. The research findings can be generalized to benefit real EV motors.
