Belt Magnetic manufacturers help you to find out why Belt Magnetic electromagnet is seriously hot
Many users have found that the internal electromagnet has a serious heart problem when using the Belt Magnetic, which causes the magnetic force of the electromagnetic iron remover to drop. So what are the result for this problem, and how to effectively overcome this problem? Take a look at the relevant instructions from Belt Magnetic manufacturers.
When utilizing the Belt Magnetic, first determine that the working voltage of the electromagnet is stable and there is no overload operation. The relationship between resistance, voltage and current is: U = R * I. If the voltage is stable, the smaller the resistance, the stronger the current. The greater the current through the unit section, the more severe the heat of the enameled wire. The more rigorous the coil is, the higher the resistance and the smaller the current, so the suction of the electromagnet will decrease and it will recover after cooling.
The second is the material problem. Generally speaking, the enameled wire refers to the copper enameled wire, which means that the conductor is copper, but the copper has new copper and recycled copper. Recovered copper has a large amount of impurities, and the conductivity is much worse than that of the new copper. Under the same conditions, there is a larger amount of heating. There is also a copper clad aluminum wire, which is quite unusual in tensile and anti-fatigue than copper wire. The conduction properties of impurities and aluminum lead to relentless heat generation.
Then there are problems in the design of the electromagnet structure: the air gap of the coil is too large, the core is not sufficiently cut for the magnetic lines, and the wind resistance of the core design is too large, which causes serious heat generation. You can also try to fit the gap or spring between the two magnets of Belt Magnetic to see if the elasticity is too large or there is more dust.
