Abstract
The traditional electric wheelchairs are equipped with a high speed motor and reduction gears. In general, the structure is space-unefficient and weight-overloded. So the thesis suggests an innovative rim motor for electric wheelchairs. A target of our paper is to design a direct-drive rim motor having high torque without the additional equipment. The novel device could be used to be not only a motor rotor but a hand-rim. This motor has high power, torque, torque density and low weight.
First of all, we should determine the torque, speed and power based on dynamic evaluation. Second, the sensitivity analysis and optimal search method would be used.
Ultimately, the optimal results would be demonstrated by the Finite-Element-Method Analysis (FEMA). Moreover, we would modify the detail dimension to eliminate the cogging torque and torque ripple. The simulation results would be eventually compared with experiments.
