Recently one of our customers, who feels very confused why the electro-permanent lifting magnet force will not disappear after power failure. Because they are currently using electromagnet lifting equipment, the materials being carried can suddenly fall off in mid-air during the operation when it encounters a power limit or a power failure, which is very dangerous. He was very interested in our electro-permanent lifting magnet products after visiting our website but was still afraid that the same situation would occur and don’t know why the electro-permanent lifting magnet force will not disappear after power failure.
The reason why customers have this doubt is mainly that many people are not very clear about the principle of the electric permanent lifting magnet products, today HVR MAG will tell you what are the electro lifting magnets & electro-permanent lifting magnets, and their difference.
The electro-lifting magnet is a lifting device that uses the electromagnetic force generated by the coil wound on the iron core to handle steel materials, so if you want to keep handling the material you must provide a constant and stable current; if the current is too small, it will cause the material to fall because the magnetic force is not strong and the lifting capacity is not enough.
HVR-MAG electro-permanent lifting magnet
The electro-permanent lifting magnet is an upgraded product of the electro-lifting magnet, which is controlled and transformed by the electric control system on the distribution of its internal magnetic circuit, so that the permanent magnetic field is balanced within the system itself, only in the moment of magnetization or demagnetization need electrical energy, in the working process of power failure does not lose magnetism, there will be no loss of magnetism after power failure.
Previously, many companies used a power outage magnetizing device to extend the demagnetization time of electromagnets to avoid various accidents caused by sudden power failure. However, the extension time of an electromagnet magnetization device is very short, which can not eliminate these hidden dangers fundamentally, and small enterprises can not afford the cost, either.
Therefore, once the electro-permanent lifting magnet is developed and produced, it is loved by the majority of enterprises, because it can solve the problem of demagnetization of power failure once and for all, fundamentally eliminating all kinds of hidden dangers that may arise from power failure, and it can also save more than 95% of electricity, which is the ideal lifting tool for modern enterprises.
