<P>PROBLEM TO BE SOLVED: To unify a levitation (guide) mechanism and a propulsion mechanism while simultaneously generating a levitation force and a propulsive force, and to stably propel a needle in a balanced manner while controlling the posture of the needle by a simple configuration. <P>SOLUTION: Magnetically levitated propulsion machinery have a stator 1, the needle 2, coils 3, and permanent magnets 4. In the magnetically levitated propulsion machinery, the coils 3 are set symmetrically to bases on both left and right side of the stator 1 or the needle 2. In the magnetically levitated propulsion machinery, the permanent magnets 4 are set on both left and right side of the needle 2 or the stator 1 while being vertically opposed to the coils 3, and the coils 3 are supplied with an electricity so as to simultaneously control a levitation and a propulsion. <P>COPYRIGHT: (C)2009,JPO&INPIT |
