JDMZ3 Series Fricative Electromagnetic Power lost Brakes

1、Applications
　　 JDMZ3 serise are fricative brakes ,which are automa-ticaly set to work when an AC power lost occurs. They are mainly usde with Y series motore to create YEJ series three-phase motore,it's widely appllcabie in machine tools and in machineries for metallurgy, construction,chemistry,food-prompt and accurate braking effect.
　　Because of its small size.light weight low noise an high reliability,it is widely accepted as an ideal piece of automation equipment.
