交流アンペール力を利用したアルミフレームの傾斜浮揚

抄録

　This paper describes a new structure for noncontact tilting floatation of an aluminum (Al) frame utilizing the AC ampere force given by the outer product of AC current in the Al frame and AC magnetic flux. It is hard to generate sufficient levitation force by using the conventional AC induction force technique when the area for eddy current to flow in the frame is not enough. On the other hand, the proposed structure applying the AC Ampere force technique achieved completely the tilting floatation of the Al frame under the condition that the secondary current flows along the frame regardless of through slits in the frame.
