PURPOSE:To obtain contractive movement, by connecting electromagnets with elastic bodies in the predetermined polarity direction to form a quadrangle. CONSTITUTION:Electromagnets A1-A4 are connected by elastic bodies P to form a quadrangle. With reference to the polarity of electromagnets A1 and A2, the inside of the quadrangle is for S-poles and the outside of it for N-poles. With reference to the polarity of electromagnets A3 and A4, the inside of the quadrangle is for N-poles and outside of it for S-poles. The electromagnets A1 and A2 repulse each other, while the electromagnets A3 and A4 repulse each other, too. On the other hand, the electromagnets A1 and A attract each other, while the electromagnets A2 and A3 each other, too. It is, therefore, possible to obtain the effect that contracts longitudinally. |
