| Outline of Final Research Achievements |
This study discussed efficiency improvement and feasibility study of in-wheel magnetic-geared motor for walking support machines. As a result, both torque increasing and loss decreasing were achieved by employing open-slot structure, low-loss core material, and interior permanent magnet rotor. Based on the results, the magnetic-geared motor was prototyped and tested. The test results demonstrated that desired torque can be obtained, and the maximum efficiency reached to 84.7%. Furthermore, it was proved that the prototype motor can be applied to walking support machines.
