Problems solved by technology

[0002] Electromagnetic actuators, such as solenoid valves, electromagnetic locks, etc., generally have two states of on or off. The existing electromagnetic actuators must be continuously energized when they are in the working state, which consumes a lot of power and generates a lot of heat, which affects The service life of other electronic components makes the service life of the overall actuator short
And once the power is cut off in the working state, the actuator and the actuator will malfunction

Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the drawings

[0030] like figure 1 , figure 2 As shown, in embodiment 1, the constant magnetic bistable actuator includes a drive circuit 5, a casing 3, a coil 4, a moving part 1, and a constant magnet 2. The driving circuit 5 is connected to the coil 4, and the moving part 1 and the casing 3 are guides. Made of magnetic material, the coil 4 and the permanent magnet 2 are between the casing 3 and the moving part 1, and are fixed in the casing 3 along the axial direction. The magnetic poles of the permanent magnet 2 are arranged radially, perpendicular to the moving direction of the moving part 1, and the same magnetic poles are opposite to each other. One end of the moving part 1 passes through the casing 3, and the part passing through is a guide rod 11, which is made of aluminum material. The magnetic force generated by the coil 4 is greater than the magnetic force of the constant magnet,...

Abstract

The invention relates to an electromechanical actuating element, in particular a constant magnetic bistable actuating element and actuator thereof, wherein the constant magnetic bistable actuation device includes a drive circuit, a casing, coils and moving elements, wherein the drive circuit connectes to the coils, characterized by that, it also includes a constant magnetic-iron, the moving elements and the casing are made of magnetic material, the constant magnetic-iron and coils are arranged between the moving members and the casing, the moving elements, the constant magnetic-iron and the casing form a closed magnet circuit, in which the magnetic force produced by coils energizing is greater than that of the constant magnetic-iron. The invention realizes less energy consumption, large magnetic flux, maximum magnetic force of moving members and more reliable operation.

Description

technical field [0001] The invention relates to an electromagnetic actuator, in particular to a constant magnetic bistable actuator and its actuator. Background technique [0002] Electromagnetic actuators, such as solenoid valves, electromagnetic locks, etc., generally have two states of on or off. The existing electromagnetic actuators must be continuously energized when they are in the working state, which consumes a lot of power and generates a lot of heat, which affects The service life of other electronic components makes the service life of the overall actuator short. And once the power is cut off in the working state, the actuator and the actuator will malfunction. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, and provide a constant magnetic bistable actuator and its actuator with low energy consumption, good safety and reliable operation. [0004] The technical solution adopted in the present inve...
