How Lifting Electromagnets Work

The principle of operation of lifting electromagnets is based on Ampere's law and Faraday's law of electromagnetic induction. According to Ampere's law, when electric current passes through a coil, it produces a magnetic field around it. And according to Faraday's Law of Electromagnetic Induction, when a conductor moves in a magnetic field, it generates an induced electromagnetic force at its ends.

Frequently Asked Questions

Lifting electromagnet cannot absorb materials

Power failure: First check whether the power supply of the lifting electromagnet is normal. Please confirm whether the power supply is normal by checking whether the power cord is damaged or loose, and whether the power outlet is working. If the power supply is normal but the electromagnetic chuck still cannot absorb objects, the coil of the electromagnetic chuck may be damaged and the coil needs to be replaced.

Coil failure: If the power supply of the lifting electromagnet is normal but it cannot absorb materials, maybe there are something wrong with the coil . Please check whether the coil is normal by using a multimeter to detect the resistance value of the coil. If the resistance value exceeds the normal range, the coil is damaged and needs to be replaced.

Failure of the lifting electromagnet surface: If the power supply and coil of thelifting electromagnet are normal, but materials cannot be absorbed, there may be a problem with the lifting electromagnet surface. Please confirm whether the lifting electromagnet surface needs to be replaced by checking whether there are scratches or wear on the surface of the lifting electromagnet. If there are scratches on the surface of the lifting electromagnet, please use sandpaper to polish and repair it; if the surface of the lifting electromagnet is severely worn, it needs to be replaced.
Lifting electromagnet cannot release materials

Power failure: Check whether the power supply of the lifting electromagnet is normal. If the power supply is normal but the lifting electromagnet cannot release the material, the relay of power may fail and the relay needs to be replaced.

Control circuit failure: If the power supply of the lifting electromagnet is normal but the materials cannot be released, the control circuit may fail. The cause of the fault can be confirmed by checking whether components such as switches, relays and fuses in the control circuit are functioning properly. If a component is found to be damaged, the corresponding component needs to be replaced.

Gap of lifting electromagnet failure: If the power supply and control circuit of the lifting electromagnet are normal, but the materials cannot be released, it may due to too small lifting electromagnet gap. The problem can be solved by adjusting the lifting electromagnet gap.
Other common faults and repair methods

Overload failure: If there is overload failure of the lifting electromagnet during lifting, it may be because the weight of the lifting electromanet exceeds its capacity. In this case, please stop it in time, unload the object, and donot restart it until it return to normal.

Over-temperature failure: Long-time use of the lifting electromagnet will cause its temperature rise. If the temperature is too high, it may affect the working effect or even damage the lifting electromagnet. In this case, please stop the lifting electromagnet, and donot restart it until it cool down.

The lifting electromagnet cannot be started: If the lifting electromagnet cannot be started, the control switch may be fail. In this case, please check whether the switch is working normally. If the switch is found to be damaged, it needs to be replaced.
