Title:
ELECTROMAGNETIC DEVICE
Document Type and Number:
Japanese Patent JP3412358
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To avoid the arrangement of a permanent magnet on a coil winding for eliminating the crossover wiring as well as facilitating the magnetization of the permanent magnet for reducing the cost.
SOLUTION: This electromagnetic device is provided with an iron core 20 passing through a coil 10, a pair of permagnet magnets in the same direction of a magnetic pole arranged with the same poles on both ends of the iron core 20 protruding from the coil 10, iron core magnetic poles 23 formed on both ends of the iron core 20, a yoke 40 connecting to the magnetic pole opposite to the iron core 20 of a pair of permanent magnets 30 to the opposite side magnetic pole as well as an iron piece magnetic poles 53 opposite to the iron core magnetic poles 23 on both ends having fulcrums 42 on the yoke 40 to be freely rotatably held contered on the fulcrums 42.
