Description
INTRODUCE
YEJ2 series electromagnetic brake motor 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 90MM and not exceed 0.2 second for frame sizes 100MM 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 motors acquire 198V directcurrent rectified from 220V AC when the power is on . At the same time , the armature is attracted by electromagnet . This makes brake disc ratable and enables motor to run freely . Whin the power is off , the electromagnet loses electromagnetic force . The armature is pushed by the spring and sticks to endshield of the motor immediately , the rotation is stopped therefor .
This series are widely used in machine tools, packaging machinery,woodworker machinery , food processing machinery , chemical engineering machinery , textile machinery , construction machinery , gear reducer and so on.
