Outline of Final Research Achievements

I developed a motor with 2 controllable output shaft, which consists of 1 set of coils. This motor enables rotary and linear motions using superimposed currents of 3 and 6 phases, where the proposed permanent magnet arrangement and stator tooth arrangement are needed. In this motor, 2 motions do not interfere with each other, and this is investigated by the simulation using the mathematical model. In order to show the effectiveness of the motor, finite element analysis under vector control and measurements on a prototype were carried out. As a result, the positioning of rotary and linear motions was available.

Academic Significance and Societal Importance of the Research Achievements

2軸独立出力モータの実用化により，これまで2台必要であったモータが1台で運用でき，特に今回の課題のような回転と直動を1つのモータで実現することにより，半導体実装機のノズルに大幅な革命をもたらす．半導体実装機のノズルは，回転モータとベルトの組み合わせで複数のノズルに対して同時に同じ運動をさせるが，これが無駄になっている．そのため，各ノズルに回転モータと直動モータが搭載されれば，全ノズルを互いに独立に駆動することが可能となり，半導体実装に要する時間が大幅に短縮されることが期待される．
