In this paper, we propose a mathematical model for evaluating the performance of an onboard energy harvester. First, the static analysis results using the finite element method and the measurement results using a prototype are compared, and the parameters are supplemented as table data. In addition, the parameters necessary for a mathematical model are identified using a damping vibration. In order to easily evaluate the harvester, we propose a mathematical model that combines the results of using the finite element method with the identified parameters. Finally, a power generation experiment is conducted, and the experimental results are compared with the simulation results to discuss the validity of the proposed mathematical model.

We have proposed a current superimposition variable flux machine for traction motors. The torque-speed characteristics of this machine can be controlled by increasing or decreasing the DC current which is superimposed on the AC current. However, because of noises and the change of coil resistances, the DC current was difficult to apply constantly. In this paper, we propose a DC current control method and verify the effectiveness by carrying out measurements on a prototype. First, the structure and control method are described. Next, the effectiveness of the proposed method is verified by using FEA. Finally, the N-T characteristics are measured on a prototype.

We propose a novel magnetic gear with a high torque density and a huge gear ratio despite the small number of magnet poles. This magnetic gear combines a magnetic flux harmonics gear with a magnetic paradox planetary gear by replacing all planetary gears with steel pole pieces. Its structure and operating principle are described, and the effectiveness of the proposed gear is verified by 3-D finite element analysis.
