Design and Analysis of AC Induction Motors with Integrated Gear Trains

This work presents a design procedure to integrate the configurations of motors and gear transmission systems with defined graph representations systematically. And, an AC induction motor and a gear train are applied as an example. The existing AC induction motor and the gear transmission are studied to conclude the characteristics of topological structure. By following the design procedure, the synthesized novel configurations of integrated gear motors are 1 with a three-link and 6 with a four-link gear train. The strength of the gear is analyzed and the capability for the transmission purpose is verified. The flux linkage, the induced voltages and the current are analyzed, and this verifies the effects of gear profiles. The torque is reduced by 8.96%, and the torque ripple is reduced by 14.23%. In addition, the torque density is increased by 1.75%. This shows that the integrated device provide more stable and efficiency output torque then the existing design.
