Abstract：To overcome the shortcomings of two kinds of inwheel motors existing in the practical application of electric vehicles, an integrated electric wheel structure was proposed based on dualrotor motor. Multiple working modes of single drive for internal and external motor, coupling drive, regenerative braking and composite braking could be realized to meet the requirements of electric vehicles under multiple operating conditions. Aiming at the complex structure of the dualrotor inwheel motor, a parametric motor model was established. With average output torque and torque ripple as optimization goal, the key structural size parameters with the greatest impact on motor optimization targets were selected, and the optimal values were determined based on the combination of parameter sensitivity and response surface methodology. The electromagnetic properties of noload magnetic field distribution, back EMF and output torque of the motor were verified by the finite element analysis. The results show that the properties are significantly improved after the parameter optimization. The segmented oblique pole can optimize the rotor structure of the dualrotor inwheel motor, which effectively reduces the cogging torque and further improves the operational reliability.
