Temperature rise of DC electromagnet: The only cause of temperature rise in a DC solenoid is the temperature rise in the coil caused by copper losses. The degree depends on the current density and heat dissipation conditions. In general, the temperature rise of DC electromagnets is smaller than that of AC electromagnets. Temperature rise of AC electromagnet: The temperature rise of the AC electromagnet is caused by both copper loss and iron loss. Depends on the following points: 1. Iron core eddy current loss and hysteresis loss. 2. Losses caused by circulating power between laminated core rivets. 3. Losses caused by short-circuit loops. 4. The internal resistance of the excitation causes coil resistance loss. In addition, it is related to the operating frequency. The higher the frequency, the longer the starting current is, and the higher the temperature rise will be. When the electromagnetic reversing valve cannot work normally, such as when the valve core is blocked and cannot move due to external force, the armature cannot be attracted to the normal position after the electromagnet is energized, the magnetic path is blocked, and the coil temperature will rise sharply, especially for AC electromagnets. , it is very easy to cause the coil to burn out in a short period of time. Therefore, attention should be paid to the cleanliness of the hydraulic system during use to avoid failure of the electromagnetic reversing valve and extend its service life.

A self-maintaining electromagnet is a special electromagnetic device that has a self-maintaining function and can maintain its original state after a power outage. This characteristic makes self-holding electromagnets widely used in many industries and fields. The following are some applications of self-holding electromagnets:

The metal inside the electromagnet includes shell, iron core, moving iron core, nuts, copper washers, copper tubes, blocks and other metal parts. After the metal parts are processed and formed, they need to undergo special surface treatment to ensure the wear resistance and anti-wear of the product. To reduce rust and improve product life and performance, let’s analyze the types and processing techniques of surface treatment of electromagnet accessories. 1. The electromagnet shell is generally made of SPCC cold-rolled plate. This material has superior magnetic permeability, low manufacturing and processing costs, and is the most widely used in the market. The electroplating processes used are generally galvanizing, electrophoresis and hard chromium plating. . Depending on the different needs of customers, galvanizing is generally blue zinc, which is environmentally friendly and affordable. Electrophoresis has a beautiful appearance, better corrosion resistance, and higher cost. The appearance of chrome plating is not that bright, but it has good corrosion resistance and the product has good scratch resistance! The price is on the high side. 2. The electromagnet core is generally made of easy-turn iron, but a few use pure iron and S10C materials. Electroplating is used respectively: zinc plating, low cost, not wear-resistant; hard chromium plating, moderate cost, poor appearance; nickel plating, more commonly used, moderate cost, the corrosion resistance and service life of the product are relatively recognized by the market. There are also Teflon plating and zinc-nickel alloy plating. The cost is higher, but the appearance and corrosion resistance of the product are the best. 3. Copper tubes. The surface of the original copper tubes is rough and the friction will be large when the electromagnet is working, which will affect the product life, so the copper tubes will be treated with Teflon. Guarantee product life and performance. Others are determined according to

Hello everyone, today I want to introduce to you the specific application of electromagnets in sorting equipment. With the development of science and technology, more and more mechanical equipment are beginning to use electromagnets for control, among which sorting machine sorting equipment is one of the most common applications. In sorters, electromagnets can be used to control the entry, exit, positioning and other aspects of goods, effectively improving the efficiency and accuracy of sorting. First, electromagnets can be used to control the entry and exit of goods. In sorters, goods usually need to be entered and exited through electromagnet-controlled doors. This can effectively avoid misoperation and improve the accuracy and efficiency of sorting. At the same time, electromagnets can also be used to control the movement of goods, such as moving goods from one sorting machine to another.
