| Outline of Final Research Achievements |
First, support materials and methods of pole-pieces of a flux-modulated type magnetic gear were investigated and shape and dimensions of the pole-pieces were optimized by a finite element method (FEM). As a result, torque of the magnetic gear was improved by over 40% and efficiency was reached to over 99%, which is better than conventional mechanical gears. Next, a magnetic-geared motor/generator, which is composed of a permanent magnet machine and a magnetic gear, was designed by FEM, and prototyped. As a result, the prototype machine demonstrated a good performance as designed. Next, a 1 kW small-scale wind-turbine generator is installed and a measurement system of voltage, current, and wind verbosity for a long-term was constructed.
