Outline of Final Research Achievements |
Modification of rotor of a spherical induction motor for improving efficiency (mainly torque per current) is examined in this work. Previous model of the rotor consists of iron spherical shell covered by copper shell, whose copper shell prevented magnetic coupling of armatures and the iron part of the rotor, which decreased the magnetic flux density, causing lower torque. Therefore a mesh structure of copper embedded in the iron shell was proposed, which was examined through 3D magnetic simulation. The result showed effectiveness of the idea, and also provided suggestion for dimensional design parameters.

Academic Significance and Societal Importance of the Research Achievements |
球面誘導モータは、連続回転が可能な球面モータの各種方式の中では出力の大きさの面で有望であり、かつ当方式は移動ロボットの駆動に使える程度の特性を持っている。一方で効率の悪さが先行研究で確認されており、その改善の方策および設計パラメータに関する知見が得られたことは実用化へのステップの一つである。今後、本成果を元に実機試験を行うことで、より実用性が高まると期待される。
