Abstract: The objective of this paper is to accurately predict the behavior of a novel high-performing electric motor for motor sport application. A compact radial-flux spoke permanent magnet machine, has been designed to achieve high torque with low weight. For this machine structure, 3D leakage effects are not negligible. In this study, analyses have been carried out using a 2D modified model that takes into account the leakage 3D effects. These 3D effects have been estimated and formulated through an easy and accessible computation that has been validated against 3D simulations. Using the 2D calibrated model, the motor performances have been evaluated over the Le Mans circuit real racing drive cycle.
