Abstract

PURPOSE:To improve the quick-response property of a movable yoke in the case when fixed yokes are magnetized by exciting currents by rectangularly disposing the fixed yoke to another fixed yoke arranged on the same straight line and making another end of one fixed yoke longer than that of the other fixed yoke. CONSTITUTION:Another ends 6a2, 6b2 of a pair of U-shaped fixed yokes 6a, 6b, one ends 6a1, 6b1 thereof are each connected to a magnetic pole of the upper end of a cylindrical fixed core 4, are opposed to the side circumferential surface of a cylindrical permanent magnet 3 on the same straight line, and each another end 20a1, 20b1 of a pair of U-shaped fixed yokes 20a, 20b, one ends thereof are connected severally to a lower magnetic pole, are opposed to the side circumferential surface of the cylindrical permanent magnet 3 in shapes rectangular to said fixed yokes 6a, 6b while the size of another ends 6a2, 6b2 of the fixed yokes 6a, 6b is formed in value longer than the size of another ends 20a1, 20b1 of the fixed yokes 20a, 20b.
