Description

[Brief explanation of drawings]

FIG. 1 is an assembled perspective view showing an example of a conventional electromagnet device;
2A and 2B are plan views respectively illustrating the non-energized state and the energized state of the excitation coil of the electromagnet device shown in FIG. 1 above, and FIG. A side view of the electromagnetic device provided with the bypass member, FIG.
FIG. 5 is a rear view of the electromagnet device shown in FIG. 3 taken along line IV-IV, FIG. 5 is an enlarged view of FIG. FIG. 7 is a sectional view of the main part of the electromagnet device before filling the auxiliary bypass member of the electromagnet device shown in FIG. 6, and FIG. 8 is a perspective view of the electromagnet device shown in FIG. FIG. 3 is a cross-sectional view of the electromagnetic device shown during filling of the auxiliary bypass member.

Claims (1)

[Claims for Utility Model Registration] The armature is attracted to the armature attraction surface of the yoke in which a permanent magnet is incorporated by the magnetic force of the permanent magnet, and when the excitation coil wound around the yoke is energized, the attraction surface of the yoke is A release type electromagnet device in which the armature is separated from the attraction surface of the yoke by reducing the attraction force with the armature, the part of the yoke holding the permanent magnet having a through hole communicating with the inside. After fitting into a frame-shaped bypass member made of ferromagnetic material, bypass correction filler containing fine particles of ferromagnetic material is injected into the gap between the bypass member and the yoke through the through hole, and the bypass is completed. An electromagnet device that integrates a member and a yoke.
