Problems solved by technology

Therefore, during operation, it is necessary to resist the magnetic force of the permanent magnet 5 and utilize the magnetic force of the coil 2 to drive the movable contact 6, so that the power consumption is relatively large.
[0005] In addition, in the release type electromagnetic device, the space for winding the coil 2 is very small, and if the coil 2 is used to obtain a large magnetic force, there is a problem of increasing the size of the device.

Abstract

This invention provides a small polar electromagnet device of small power consumption. Provided is a polar electromagnet device in which a drive shaft (61) is supported so as to reciprocate in an axis center direction at a center hole (31c) of a spool (31) wound with a coil (32), a movable iron core (42) is attached to a lower end of the drive shaft (61) on the same axis center, and the drive shaft (61) is reciprocated with the movable iron core (42) which reciprocates based on excitation and demagnetization of the coil. A permanent magnet (45) is integrally arranged at the movable iron core (42) on the same axis center.

Description

technical field [0001] The present invention relates to an electromagnet device, in particular to a polarized electromagnet device provided with permanent magnets. Background technique [0002] Conventionally, as a polarized electromagnet device, there is a release type electromagnetic device characterized by comprising: a movable armature held freely projecting in a predetermined direction, a fixed armature disposed opposite to the movable armature, and a protruding armature. A release spring (引外しばね) that biases the movable armature in a direction, a permanent magnet that keeps the release spring in a charged state, and a magnetic flux passing through the movable armature from the permanent magnet and the The yoke of the magnetic circuit of the fixed armature, the electromagnet that forms a diamagnetic field opposite to the magnetic field generated by the permanent magnet according to the detection result of the abnormal current, and the engaging surface when the movable ar...
