あうた。Conventionally, this type of polar electromagnet was of the latching type (
There are two types: a bistable type (bistable type) and a single type (monostable type).In order to obtain both of these types, the single tie type is basically a latching type with a completely symmetrical magnetic circuit.
In order to make the magnetic circuit asymmetric, this was done by changing the shape of the yoke or armature air, or by providing a non-magnetic range 1alp L/-) on the armature air or yoke, but in this case, the manufacturing Problems arose when the number of parts increased due to the number of processes and the need to add additional parts.

鉄片６は平板状の磁性体よりなり、−面６ａがコイル４
の励磁条件により鉄芯２の磁極部２ｂと当接又は開離す
る如く、前記磁極部２ｂに対向して設けられている。In Fig. 1, 1 is a yoke, which has a generally U-shape. An iron core 2 is attached to one end 1a, and a flexible permanent ♂ is attached to the other magnetic pole part 1b, which is one magnetic pole part. Stone 3 is installed. The coil frame 5 with the coil 4 wound therethrough is inserted into the middle of the iron core 2, and one end 2a is fixed to one end 1a of the yoke 1, and the other magnetic pole part 2b is connected to the other end magnetic pole part 1b of the yoke 1. It is placed opposite to. 3 is a flexible permanent magnet made of an elastic rubber magnet or the like, and its base end 3b is connected to the yoke 1. The other end 1b is particularly attached by using an adhesive or the like, and the movable iron piece 6 is attached to the free end 3a by gluing or the like. The movable iron piece 6 is made of a flat magnetic material, and the negative side 6a is connected to the coil 4.
It is provided facing the magnetic pole part 2b of the iron core 2 so as to come into contact with or separate from the magnetic pole part 2b according to the excitation conditions.
尚、本実施例は９−り１と鉄芯２で磁路を構成して込る
が、磁路が形成できるのであれば第２図の如く中間にコ
イル４を巻装しかつ、対向した両磁極部１ｂ、２ｂを形
成した構成としてもなんらさしつかえなく１本実施例に
限定されるものでな−。In this embodiment, a magnetic path is constructed by the 9-ri 1 and the iron core 2, but if a magnetic path can be formed, a coil 4 is wound in the middle as shown in Fig. The configuration in which both magnetic pole portions 1b and 2b are formed is not limited to one embodiment.

流は小さくてす２ものである。When a current is passed through the coil 4 from the direction A as shown in FIG. In this case, if the force of the flexible permanent magnet 3 to maintain the closed magnetic path state due to its magnetic force is made larger than the return force of the flexible permanent magnet 3 to return to the open magnetic path due to its own elastic force, the energization of the coil 4 can be stopped. Also, the movable iron piece 6 is kept in contact with the other end 2b of the iron core 2.
Ru. Next, when current is applied to the coil 4 from the B direction as shown in FIG. It separates from 2b and returns to its original state. At this time, the restoring force of the flexible permanent magnet 3 is added to the above-mentioned magnetic repulsion force as a restoring force, so the current flowing through the coil 4 for returning is small. .
以上の構成により双安定動作を行うラッチングタイプの
有極電磁石を得ることができる。With the above configuration, a latching type polar electromagnet that performs bistable operation can be obtained.
又、前記の場合は可撓性永久磁石３の持つ磁力を自らが

るものである。Also, in the above case, the magnetic force of the flexible permanent magnet 3 is made larger than its own elastic force, but by selecting the material and shape of the flexible permanent magnet 3, the force relationship between the two can be reversed. When the elastic force is made larger than the magnetic force, when the coil 4 is energized from the direction A, the movable iron piece 6 is attracted to the other end 2b of the iron core 2 as described above, but if the coil 4 is de-energized, The movable iron piece 6 returns to its original state due to the elastic magnetic force of the flexible permanent magnet 3, and a single-type polarized electromagnet that performs so-called monostable operation can be constructed.

構成することができるものである。As described above, the present invention includes a flexible permanent magnet having one end attached to one magnetic pole part of the iron core and a movable iron piece facing the other magnetic pole part of the iron core attached to the other end. This makes it extremely easy to create a lagging type by simply selecting the force relationship between the magnetic force and elastic force of the flexible permanent magnet, without changing the shape or dimensions of the parts used or adding other parts as in the past. Furthermore, it is possible to construct a single type polarized electromagnet of either type (b) or (c).
