A wind-tunnel system for spinning body has been proposed to measure hydrodynamic forces acting on the body. In the proposed system, the body is suspended and rotated by electromagnets. The forces are measured from the control signal for suspension. In the conventional apparatus, eight electromagnets were placed around the wind-tunnel. An optical displacement sensor was used to detect the three-dimensional positions of the body. Stable suspension and three-dimensional positioning of the body were achieved. However, the conventional apparatus has some problems. In this paper, a new wind-tunnel using magnetic suspension to improve such problems is fabricated. Stable suspension using fabricated apparatus is achieved.
