Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] Such as figure 1 As shown, the bistable electromagnetic steering gear consists of a housing 6, two symmetrical E-shaped iron yokes: a first iron yoke 1-1 and a second iron yoke 1-2, a central rotating shaft 5, a first permanent magnet 301, and a first permanent magnet 301. Two permanent magnets 302, the mover 4, and the rudder wing 7 connected with the mover 4 constitute. The first iron yoke 1-1 includes a first limiting arm 111 and a second limiting arm 112 ; the second iron yoke 1-2 includes a third limiting arm 121 and a fourth limiting arm 122 . A first coil 201 and a second coil 202 are wound on the first iron yoke 1-1; a third coil 203 and a fourth coil 204 are wound on the second iron yoke 1-2.
[0019] Such as figure 2 As shown, when the mover 4 is locked at a limit position, for example, when the first mover arm 40...

The invention provides a bistable electromagnetic steering gear based on E-shaped iron yokes and an operating method. The bistable electromagnetic steering gear consists of a casing, two symmetrical E-shaped iron yokes, two coils wound on each E-shaped iron yoke, a central rotation shaft, a mover, a rudder wing connected with the mover and two permanent magnets. At an extreme position, the magnetic flux generated by the permanent magnets keeps the mover locked. The coils wound on the iron yokes are energized to generate new magnetic flux. The mover is controlled to rotate to another extreme position. By changing the direction of current flowing into the coils, the mover and the rudder wing deflect between two extreme positions formed by the E-shaped iron yokes. According to the invention,the structure is simple; a load can be driven in two directions; energizing is carried out when the deflection angle is switched; after the power is turned off, the magnetic flux created by the permanent magnets is used to lock a core; and the energy consumption is low.
Description
technical field [0001] The invention relates to a steering gear, in particular to a bistable electromagnetic steering gear and an actuating method based on an E-shaped iron yoke. Background technique [0002] The electromagnetic mechanism has few moving parts, simple structure and high reliability, which meets people's requirements for gradually improving the performance of the steering gear: compact structure, small size, and light weight, while the traditional steering gear mechanism has complex structure, large mass and volume. , difficult to control and many other shortcomings. In the existing technology, electromagnetic coils are used to drive and output linear motion, and then the linear motion is converted into rotary motion. Therefore, an electromagnetic steering gear with simple structure, small size, and electromagnetic direct drive is required. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the object of the ...
