Abstract
PURPOSE:To change a magnetic attractive force and facilitate the control of electromagnets, by providing a cutout in a magnetic circuit of the electromagnets and rotating a gear-shaped magnetic member, which has projections, to cover the cutout. CONSTITUTION:Coils 14 are connected to each other at 24 to form a circuit 24. A magnetic member 19 is rotated at a uniform speed by a motor 21. When the cutout 13 of a core 12 corresponding to an armature 17a is not covered by the projections 20 of the magnetic member 19, a current is caused to flow through the circuit 24 to eliminate the magnetic flux of a loop. At that time, the cutout 13 of the core 12 corresponding to another armature is covered by the projections 20 of the magnetic member 19 and only the armature 17a is released. When the current is cut off and the magnetic member 19 is rotated and the cutout 13 of the core 12 is covered by the armature 17a, this armature is attracted by the core. According to this constitution, the number of turns of the coils can be small, an applied voltage may be low and only one control circuit is needed for an electromagnet set, resulting in facilitating control.
