Abstract
The IWME (Integrated Wheels of Mechanics and Electrics) includes an In-Wheel PMSM (Permanent Magnet Synchronous Motor), a reduction device, a brake device, the lubricating and cooling system, and so on in the hub of the tyre. It’s the key factor to improve the performance of EV (Eletric Vehicle) and HEV (Hybird Electric Vehicle). In this paper, The IWME will be applied to a special type vehicle and mid-heavy vehicle; its integrated composition is complex. The authors have advanced the simulation analysis method of the motorized wheel based on PMSM. By the method, the main dynamic system parameters of the IWME are analyzed and simulated forward and backward with the Matlab/Simulink models of the IWME and the vehicle, in order to adapt the vehicle and to test its dynamic response. With the FEA (Finite Element Analysis), the optimization design of the IWME has been achieved. The shell structures and supporters of major components and parts have been strengthened. By evaluating the final optimization results, integrated design level has been improved according to the design method in the paper. Copyright Form of EVS25.

The more and more Motorized Wheels have been applied to the bicycle, micro car or mobile machinery shop, but the IWME applied to the special vehicle and mid-heavy vehicle is needed different dynamics performance and more rigorous structure
Summary
The IWME (Integrated Wheels of Mechanics and Electrics) includes an In-Wheel PMSM (Permanent Magnet Synchronous Motor), a reduction device, and a brake device, the lubricating and cooling system, and so on in the hub of the tyre. Based on the system engineer theory [3], the IWME can be divided into five systems: drive system (PMSM in hub), tyre system, brake device, reduction device, auxiliaries system, the each of five systems can be divided into several subsystems too (shown as picture). Based on the system engineer theory [3], the IWME can be divided into five systems: drive system (PMSM in hub), tyre system, brake device, reduction device, auxiliaries system, the each of five systems can be divided into several subsystems too (shown as picture1) The relations among these several subsystems is very complex, the working conditions of these subsystem are harsh too.
