Description

YEJ2 series electromagnetic-brake motors are improved products on the base of YEJ series . The technical properties of its motor conform to the requirements of Y2 series .The performances of the brake assembly are improved . 　　YEJ2 can make action promptly when the power of electric motor is off . Quick brake time doesn&#**9;t exceed 0.*5 second for frame sizes *3MM up to *0MM and not exceed 0.2 second for frame sizes **0MM up to **0MM . This series can acquire slow brake time by changing the connection in the terminal box as per customer&#**9;s request . 　　This series have low noise and the braking performance is reliable .　　This series are widely used in machine tools, packaging machinery, woodworker machinery , food processing machinery , chemical engineering machinery , textile machinery , construction machinery , gearbox and so on. OPERATING CONDITIONS Ambient temperature: *****0 oc Altitude: Altitude should be lower than ***0meters above sea level. Rate voltage: **0v **0v **5v Rate frequency: *0Hz *0Hz. Connection: Star-connection for 3Kw or less whereas delta-connection for 4Kw or more. Duty/Rating: Continuous(S1) Insulation class: F, the temperature rise of the stator winding is examined at *0K(by resistance method). Protection class: IP*4/IP*5. Cooling method:IC**1
