Description

REMANENT MAGNET AND CORE ROTATING RELAY}

The present invention relates to an electromagnet relay, and more particularly, a permanent magnet having an iron core structure which operates in response to a change in the magnetic pole of an electromagnet in response to a change in the magnetic pole of the electromagnet and forms a magnetic path connecting the permanent magnet and the magnetic pole flow. The present invention relates to a relay having a permanent magnet rotor for applying a force of an electromagnet and an electromagnet at the same time so that a strong electromagnetic force is applied to the relay.

In general, a polarized electromagnetic relay using a permanent magnet is a unidirectional relay and a bidirectional relay. These relays are a type in which the relay is closed by the force of the permanent magnet and the electromagnet, and the relay is opened by the force of the spring. Because the strength of the return spring against must be strong, it is a structure that is hampered by the operation.

Japanese Laid-Open Patent P2009-267988 (KITA HIROYUKI) 2009.11.25 Publication date 2011.6.9 is a structure to reinforce the operation of the relay by inserting a permanent magnet near the iron core of the electromagnet, but also corresponds to a strong permanent magnet suction force on return There is a disadvantage in that power consumption is great because it requires an electromagnetic force.

United States Patent US 2002 / 0021198A1 (Johannes Oberndorfer) 2011.Jul.18 is a relay in which both pairs of permanent magnets are operated by suction and repulsion according to the polarity of the electromagnet, with each pair of permanent magnets wrapped around the magnetic poles of the relay. It can be seen that the operation of the operation is very efficient, but there is a difficulty in the installation of the structure and the installation of the interlocking mechanism corresponding to the wide range of operation.

In addition, since the bidirectional relay operating in the form of a general seesaw must use a strong return spring, there is a problem that causes a lot of motion loss when operating with electromagnetic force.

The present invention has been made to solve the above problems, the most important thing in the operating characteristics of the electronic relay, when operating the power is applied, the drive input is less, the operation is required lightly while the operation distance is increased smoothly the contact, etc. It is also a task to reduce the power consumption of the relay to be able to operate, and also to return lightly even when the power supply of the relay after the operation to operate even with less elasticity of the spring.

In addition, when the relay completes the operation, the flow of the magnetic flux by the relay should be configured to have no leakage of magnetic flux by the electromagnetic force by the magnetic flux circuit forming a complete closed circuit to minimize problems such as noise and heat generation.

The present invention to solve this problem is less power consumption during operation, when the operation is completed to form a closed loop of the complete iron core to prevent leakage of magnetic flux and also to return to respond to the spring is not strong when returning the object There is this.

The present invention is to solve the above problems, in one embodiment of the present invention in the structure of the rotatable movable portion is installed on both ends of the electromagnet structure generally used, the rotatable movable portion becomes a closed circuit path of the electromagnet Thus, it operates even in weak electromagnetic force, and when it returns, it is restored to a spring that is not strong so that a relay that can operate smoothly can be obtained.

In the above operation, if one pair of electromagnetic poles is placed at a predetermined interval by one pair of permanent magnets, one of them is inhaled and the other side is repulsed.

Of course, if one pair of permanent magnets is used in one electron pole, the operation is sure and strong, but high effect can be obtained in a narrow volume, and the rotor structure is formed at the center by dividing the center of one electron pole in consideration of the simplicity of the supporting structure. When the rotor is installed, structural stability can be easily obtained, and the operation characteristics are also good.

In addition, the same type of rotors are formed on the electric poles at both ends, and the cores are connected to each other to form a complete iron core closed circuit.

The relay having a permanent magnet with a rotating iron core according to the present invention can obtain a strong relay operation with a small drive by using a strong suction and repulsion properties in a narrow gap of the permanent magnet, the relay can be operated with a small power consumption, so the coil It is possible to prevent the breakdown caused by the burnout of the machine and to ensure the safe operation of important machinery, and also to improve the performance can reduce the production cost and maintenance costs can be expected to operate economical machinery.
