Fat 4；Iron core 2 is equipped with the electromagnetism iron frame 1, and coil 3 is wound with outside iron 2, the full epoxy resin 4 of filling in electromagnetism iron frame 1, also
Including flexible circuit board 5, controller（Not shown in figure）, current sensor 6 and Magnetic Sensor 7；The flexible PCB 5 is installed
On the inner wall of electromagnetism iron frame 1；The flexible PCB 5 is embedded with controller, and controller is connected with coil 3；The electric current
Sensor 6 is arranged in electromagnetism iron frame 1, and for the current strength of induction coil 3, and current sensor 6 is connected with controller；Institute
State and Magnetic Sensor 7 is additionally provided with electromagnetism iron frame 1, above-mentioned Magnetic Sensor 7 is connected with controller, and the magnetic field for induction coil 3 is strong
Degree.
When the solenoid is energized, when current sensor senses that the electric current of coil is in the scope of setting, electromagnet is represented
Suction stablize；When current sensor senses that the electric current of coil is in outside the scope of setting, controller is automatically in coil
Electric current be adjusted, the current value made be in setting in the range of, can thus keep the suction of electromagnet to stablize；When magnetic passes
When sensor senses that the magnetic field intensity in electromagnetic actuation face is in outside the scope of setting, the voltage in controller adjust automatically coil
Output, and then control coil size of current keeps the stabilization of electromagnet suction；It is actual in use, by Magnetic Sensor and
Current sensor detects the relevant information of coil in real time, and the information of coherent detection is fed back to controller, finally controls
The feedback information of device combination Magnetic Sensor and current sensor processed, carries out dual regulation to the magnetic field intensity of coil in real time, ensures
The suction stabilization of electromagnet is in the scope of setting.
Further, booster circuit is also associated with the controller, for improving the voltage of coil；In actual use,
Increase booster circuit be in order to avoid electromagnet rated voltage work under be unable to reach require when, the boosting in short-term to coil,
And then the adsorption capacity in short-term of electromagnet is improved, so electromagnet can be used in different environments.
Further, serial port circuit is also associated with the controller, and serial port circuit is connected with controller, for setting
