Simulation and Design of Unlocking Device With Electromagnet and Permanent Magnet Intermodulation

According to the mechanical control requirements of connection in industrial systems,an electromagnet and permanent magnet intermodulation unlocking device was designed.The device accurately takes the repulsion force between electromagnet and the permanent magnet as the unlocking force,and the magnetic force of the permanent magnet to the electromagnet core as the locking force.Initially,the intermodulation between electromagnetic force and permanent magnetic force was analyzed by magnetic circuit theory.Then the simulation software was used to analyze the effect of key structural parameters of yoke on the unlocking force.As a final point,according to the research results,a prototype of 45mm×40mm×40mm was developed.It is proved that the device has all advantages of simple structure,low power consumption,light weight,small size and reliable performance with adjustable locking force,unlocking force and working stroke.It has prominent prospects in the field of mechanical control.
