The MT long stroke traction electromagnet is composed of a coil, a moving iron core, and a static iron core power controller. The structure is a shell like structure, applying the leakage magnetic flux principle of a spiral tube, and utilizing the electromagnetic moving iron core and the static iron core to engage for a long distance, with a stroke of over 40mm --60mm. Realize the linear reciprocating motion of the traction rod. Adopting the principle of power supply and electronic control conversion, high-power startup, and low-power maintenance, Hebei Qinneng patented demagnetization technology. The electromagnetic traction force reaches 300 kilograms. The traditional AC traction electromagnet starts and operates at a voltage and current, which is prone to burning the coil, causing limited traction and limited travel. The action of the long-distance traction electromagnet is simple and rapid, rising for 0.10 seconds and returning for less than 0.05 seconds. The operating frequency is over 3600 times/hour. The power supply can be AC, DC or AC/DC shared. Can start work frequently and can also be powered on and closed for a long time. It can be used as an executing mechanism in various simple or complex process flows to achieve remote control, centralized control, or automatic control. Widely used in industries such as power, machinery, metallurgy, mining, petroleum, chemical, lifting, cement packaging, etc. It has the characteristics of reliable performance, sensitive action, and long service life
