Assessment of the Energy Consumption and Drivability Performance of an IPMSM-Driven Electric Vehicle Using Different Buried Magnet Arrangements

This study investigates the influence of buried magnet arrangement on efficiency and drivability performance provided by an on-board interior permanent synchronous machine for a four-wheel-drive electric car with two single-speed powertrains. The relevant motor characteristics, including flux-linkage, inductance, electromagnetic torque, iron loss, total efficiency, are analyzed set six configurations suitable specific machine, which is controlled through maximum-torque-per-ampere maximum-torque-per-voltage strategies. Moreover, impact each in connection energy consumption along four driving cycles, as well longitudinal acceleration gradeability considered vehicle. simulation results identify most promising rotor solutions, show that: (i) appropriate selection configuration especially important cycles substantial high-speed sections; (ii) has major maximum torque below base speed, thus performance; (iii) that excel among worst terms drivability, vice versa, i.e., at vehicle level, trade-off between dynamics.
