The operation principle of this proportion electro-magnet is: when the coil is energized, and the magnetic line of force forms closed-loop path through buting iron 2, stroke pad 4, air gap 10, armature 6, pole shoe 7, yoke 8.Owing to air gap is made up of air, its permeability is far below other part being made up of permeability magnetic material, and therefore flux loop forms approximation open circuit at air gap, forms the two poles of the earth (N pole and S level) of Magnet, produce magnetic attraction force at magnetic line of force approximation open circuit.Owing to armature is permeability magnetic material and movable, the one-level as Magnet is attracted by another pole and produces motion.The utilizable action source that excess current control obtains i.e. is led in this motion, promotes the workpiece such as main valve to move the work of electromagnetic valve.
Owing to buting iron 2 have employed special structure, the magnetic line of force by buting iron 2 to armature 6 time, if being divided into stem portion, wherein a road magnetic line of force is vertical with armature 6 end face, and its excess-three road all by buting iron 2 thin-walled oblique angle structure and becomes other angle with armature 6.Thin-walled oblique angle structure in buting iron 2 is owing to playing the segmentation effect of magnetic circuit, often referred to as magnetic shunt.When armature 6 motion is subjected to displacement (referred to as stroke) change, air gap changes, existence due to magnetic shunt, the magnetic circuit shunting action of magnetic shunt makes the magnetic line of force mutual proportionate relationship on aforementioned four tunnels change, total effect makes armature 6 be basically unchanged when armature travel changes by electromagnetic attraction, i.e. electromagnetic force is the most relevant with input current, unrelated with the stroke of armature.Thus, we can be by obtaining corresponding controllable output electromagnetic force to the control of input current, and electromagnetic force is linearly proportional with input signal, referred to as proportion electro-magnet.
Actual application shows, this proportion electro-magnet has the highest sensitivity (frictional force is little, movement parts quality is little), life-span length and can antipollution, it is adaptable in the multiple hydraulic system needing accurate pressure to control.
For this proportion electro-magnet, power output FIAnd the relation between electric current I is:
FI=KI×I
Wherein, FIElectromagnetic attraction (with curent change)
