When the in-wheel motor is working, it will be affected by gravity, centrifugal force and electromagnetic force. These three kinds of mechanical loads will affect the mechanical stress characteristics of the in-wheel motor, and then affect the reliability of the in-wheel motor structure. In order to understand the influence of the above loads on the mechanical stress of the in-wheel motor, this paper takes a 15-kW built-in permanent magnet in-wheel motor as the research object. Based on the establishment of the electromagnetic field and structure field coupling analysis model of the in-wheel motor, the mechanical stress of the in-wheel motor under different mechanical loads under rated and peak conditions are calculated and analyzed, and the influence of different mechanical loads on the stress and deformation of the in-wheel motor are studied. The research results show that, regardless of the rated operating condition or the peak operating condition, the in-wheel motor has the largest mechanical stress and deformation under the combined action of centrifugal force and electromagnetic force, and the smallest mechanical stress and deformation under the action of gravity only; under the same load (except for the case of gravity only), the stress and deformation of the in-wheel motor under the peak operating condition are larger than those under the rated operating condition; and the maximum stress and deformation of the in-wheel motor appear at the rotor magnetic bridge and the inner edge of the rotor, respectively, so the rotor is an easily damaged part of the in-wheel motor.
