The axial flux with amorphous alloy stators has the virtues of high power density, high torque density, compact structure. But specific to the disadvantage of restricted space of in-wheel, the compact axial flux in-wheel motor was proposed in this paper. The in-wheel motor’s performance affects the dynamic and security of electric vehicles directly. And the electromagnetic loss has a significant impact on in-wheel motor performance. To demonstrate the influence of electromagnetic loss on the thermal behavior of the machine, thermal analyses employing magneto-thermal coupling simulations have been performed. Then the experimental prototype was manufactured and tested. The simulation of the output power model was verified by test value, proving that the magneto-thermal coupling simulation is feasible. Therefore, this design technique provides a reference for the in-wheel motor structure.

Overall the benefit of Supply Chain Based on probabilistic production and power equilibrium, the influencing factors of the decision-making of probabilistic productions are studied in this paper. Firstly, the correlation function of profit is formed by solving the lowest utility of products. Then numerical simulation and example research are carried out. The results show that, there is a positive correlation property between the two types of products which formed probabilistic production and supply chain efficiency. At the same time, manufacture and retailer should also pay attention to the proportion of the two types of products in order to achieve the best overall benefit. The conclusion in this paper has practical significance, it has a significant impact on the decision-making under the power equilibrium.
