Electromagnet product design considerations
Whether it is a DC electromagnet or an AC electromagnet product, there are many factors to be considered in the design, and which aspects need to be considered.
1. The smaller the stroke, the greater the strength. When asking about strength, the stroke must be added, because the two are directly related
2. Under normal circumstances, the greater the power, the greater the strength, which is approximately proportional. When the power reaches a certain level, the electromagnet is close to magnetic saturation, and the force increase is very small
3. If the resistance, current, and voltage change, but the power remains the same, and the size of the wire package remains the same, the power is basically unchanged.
4. For the same resistance, if you increase the number of winding turns (change the enameled wire with a larger diameter), the power will increase, but if the original enameled wire is already full, you cannot change the enameled wire, otherwise the wire package will be too large, so that Can't fit in iron case
5. For the same enameled wire diameter, increasing the number of turns, the strength will be slightly reduced (because the resistance has increased, its weakening of the strength exceeds the increase of the number of turns on the strength)
6. Change the diameter of the enameled wire (resistance changes accordingly), but the power remains unchanged (P=U2/R; R, U are changed, so that P remains unchanged), the power remains unchanged
7. The length of the working time determines the size of the power. When the power is turned on for a long time, the power should not be too large, otherwise it will be easy to heat and burn out.
The electromagnet plays a very important role in the industry and is a basic electrical appliance, known as the "king of electrical appliances". With the continuous development of the magnet and iron removal equipment market and the intensification of competition, users not only have higher requirements for the quality of electromagnets and iron removal equipment, but also put forward higher requirements for production efficiency.
