.Push-pull electromagnet is mainly composed of four parts: shell, fixed iron core, moving iron core and coil. After the coil is energized, the moving iron core produces axial linear motion, which has the function of pushing and pulling the external load device. Due to the use of highly permeable materials and a magnetic circuit structure with a tapered fit, the product, although small in size and light in weight, has a shorter stroke and attraction force than conventional small electromagnets.
, .. The push-pull electromagnet plays a very important role in the industry. It is a kind of basic electrical appliance and is known as the king of electrical appliances. With the continuous development and intensified competition of the magnet and iron removal equipment market, users are not only interested in electromagnetic There are higher requirements for the quality of iron and iron removal equipment, as well as higher requirements for production efficiency. In order to improve the quality and production efficiency of electromagnets and iron removal equipment, enrich our country's product categories, enhance industry product visibility, promote The development of China's electromagnet and iron removal equipment industry promotes the research and application of electromagnet and iron removal equipment technology at home and abroad, and organizes some activities

, ..Output requirements:
, ..Strength/stroke: Stroke refers to the position of the push-pull electromagnet slide rod relative to the fully closed The distance of the state position. The electromagnet will produce different forces at different strokes. Generally, the smaller the stroke, the greater the force. (The ideal state is that the force/stroke (curve) generated by the electromagnet is consistent with the load requirement)
, .B. Response time: The time from when the electromagnet is energized to when the slide bar completes the expected displacement
, .Cyclic load: Periodic load [power-on time/(power-on time + power-off time)]*.Electromagnet is energized It will generate heat, so the cycle load and the longest energization time determine the temperature rise of the electromagnet. The temperature rise of the electromagnet and the ambient temperature determine the selection of the electromagnet insulation level: (insulation level ℃//B/)
, . .Input conditions:
, power supply type and power: different input current waveforms determine the action mode of the electromagnet. Specific applications include: AC/DC (constant voltage source/constant current source/battery/dry battery DC power generation machine/capacitor)/rectifier filtering method, etc.
, .Diode rectification: If the electromagnet uses AC power, a rectifier needs to be used to convert AC into DC. In principle, the rectifier should be designed as a full-band rectifier. The peak value of the rectifier component The conversion voltage should be three times the driving voltage of the electromagnet. The current (power) and output power have an approximately proportional relationship within a certain range. When the power reaches a certain level and the electromagnet reaches magnetic saturation, the power will no longer increase. In addition, the power Proportional to the temperature rise
, .3. Environmental factors and lifespan:
, .Environmental conditions and expected lifespan are important considerations when using different materials or protective treatments for electromagnets. Environmental factors include: temperature/humidity /Magnetic field/Electric field/Polluting corrosive gases. Liquid or dust/Vibration and shock impact, etc.
