<p><P>PROBLEM TO BE SOLVED: To provide a small-sized and lightweight thrust generation mechanism which is made small by canceling a magnetic attraction force that is operated between an armature and a movable element, and in which leakage magnetic flux is reduced. <P>SOLUTION: A thrust generation mechanism comprises: magnetic pole teeth, cores, armature winding wires and a movable element. The magnetic pole teeth are disposed to sandwich and hold therebetween a permanent magnet disposed in the movable element. The cores continuously connect the magnetic pole teeth sandwiching and holding the magnet therebetween. The armature winding wires are collectively wound around a plurality of cores. The movable element is configured by arranging magnetic poles of magnets side by side in such a manner that their front and rear sides become alternate. An armature core includes magnetic pole teeth disposed to sandwich and hold the permanent magnet therebetween and a core continuously connecting the magnetic pole teeth holding the magnet. A plurality of the armature cores are disposed along a length direction of the movable element, and a common winding wire is disposed in the plurality of armature cores. The magnetic fluxes generated by the plurality of armature cores are in the same direction, thereby reducing leakage magnetic flux and miniaturization of the thrust generation mechanism. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
