Permanent magnet with adjustable magnetic field
Product introduction
Permanent magnets have great advantages over electromagnets in generating a constant magnetic field, but their single structure and unchangeable magnetic field limit their application to a certain extent. Our company devotes itself to developing permanent magnets with adjustable magnetic fields, which make their air gaps adjustable, magnetic field strength adjustable and uniform area stable, so that the functions of permanent magnets are closer to electromagnets and their volume is smaller than electromagnets, thus making them more widely used.

Adjustable air gap permanent magnet |
The air gap of the magnetic field is adjustable, and the magnetic field weakens when the distance between the two poles increases. Changing the magnetic field by changing the air gap has simple structure and easy operation. The pole diameter is 100mm, the pole surface diameter is 100mm, the air gap adjustable range is 10-100mm, and the magnetic field adjustable range is 0.2-0.8 T .

Low field adjustable permanent magnet |
The air gap of the magnetic field is fixed, and the relative position of the pole heads is unchanged, so that the magnetic field is changed by changing the width of the magnetic circuit channel. |

Double-magnetic-axis magnetic field adjustable permanent magnet |
SCY-1.2 permanent magnet adjusts the magnetic field by changing the magnetic circuit without changing the relative position of the magnetic poles, thus realizing the function of an electromagnet without requiring an excitation power supply. It is light in weight and easy to operate, and can manually adjust the magnetic field. The reserved input shaft can also be connected with a speed reducer or a stepping motor, and the magnetic field strength can be adjusted electrically, with the adjustment precision reaching 1Gs. range 5 mm-25 mm. When the air gap is 5mm, the maximum magnetic field is 1.2T and the adjustable range of magnetic field is 0-1.1 T .. |
