摘　　要：目前煤矿用电磁铁多为带导向筒的,在控制电压12 V情况下启动电流为120 mA;结构复杂;启动电流大,在阀芯吸合后需要持续通电维持吸合状态,功耗大。针对上述问题,经过结构改进优化,研发一种单线圈永磁式自锁电磁铁,省去原电磁铁结构中的导向筒部分。仿真计算表明:在12 V控制电压下,电磁铁启动电流为81.5 mA,阀芯吸合后由永磁力保持吸合状态,不需给电磁铁持续通电,实现结构简单和低功耗要求。In order to simplify the complex structure of coal mining electromagnets mostly installed with guide tubes with 120 mA starting current of the electromagnet under the control voltage of 12 V,and reduce enormous power cosumption due to large starting current and continuous power energizing to maintain valve core pulling-in state,a single coil permanent magnet self-locking electromagnet which eliminates the guide cylinder in the original electromagnet structure is developed through structural improvement and optimization.The simulation calculation shows that under the control voltage of 12 V,the starting current of the electromagnet is 81.5 mA,and when the valve core is pulled in,the permanent magnetic force maintains the pull-in state without continuously energizing the electromagnet,which achieve the gaols of seimple structure and low power consumption.
