YEJ2 series electromagnetic-brake motors are improved products on the base of YEJ series.The technical properties of its motor conform to there quirements of Y2 series.The performance of the brake assembly are improved.YEJ2 can make action promptly when the power of electric motor is off.Quick brake time doesn't exceed 0.15 second for frame sizes 63MM up to 30MM up to 160MM.This series can acquire slow brake time by changing the connection in the terminal box as per customer's request.This series have low noise and the braking performance is reliable.
The working principle:
The electromagnetic brake get 99 or 170V DC voltage through the 220V AC or rectifier.At the same time,thearmature is attracted by electromanet,this makes brake discratable and enables motor to run freely.When the power is off the electromagnet loses electromagnetic force.The armature is pushed by the spring and sticks to end shield of the motor immediately,the rotation is stopped therefore.
