DHM3系列电磁失电制动器为通电脱离（释放），断电弹簧制动的摩擦制动器。它主要用于Y系列电动机配套成YEJ系列电磁制动三相异步电动机。广泛应用于冶金、建筑、化工、食品、机床、印刷、包装等机械中，及在断电时（防检）制动场合。

　　这种制动器具有结构紧凑、安装方便、适应性广、噪音低、工作频率高、动作灵敏、制动可靠等优点，是一种理想的自动化执行元件。可另加防护圈，提高防护等级为IP54。

　　Appication:The DHM3 brake is fricative brakes,which are auto-matically set to work when an AC power lost occurts.They are mainly used with Y series motort to create YEJ series three-phase motors. it's widely applicable in machine tools and in machineries for metal-lurgy,construction,chemistry,food-prompt and accurate braking effect.

　　Because of its small size,light weight,low noise and high reliab-ility,it is widely accepeted as an ideal piece of automation equipment .It can be add protection circle to increase protection grade:IP54.
