Abstract

PURPOSE: To position the permanent magnet which is disposed in the center in the direction twice the number of magnetic poles by providing magnetic poles at an equal spacing on the inner side of a circular iron core, mounting reverse-wound parallel coils, connecting these mutually as specified and selecting three center terminals as specified thereby energizing the coils.
CONSTITUTION: Reverse-wound parallel-connected coils are provided to magnetic poles 2 thru 6. A closed circuit is then made in an approximately star shape like outer terminal 7b to innter terminal 9a and 9b to 11a. The center terminals 12 thru 16 of respective coils are led out. If the terminal 12 is made + and terminals 14, 15 -, then the magnetic pole 2 is strongly magnetized to N, the magnetic poles 4, 5 are weakly magnetized and a permanent magnet 17 stops in the specified position. Stable positioning may be performed by supplying power to the 3 terminals in this way and the potentials on the negative pole side become differential, whereby residual vibrations are suppressed. This method enables the actuator 17 to be positioned in the direction twice the munber of the magnetic poles.
