Property and Features:
| 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't exceed 0.15 second for frame sizes 63MM up to 90MM and not exceed 0.2 second for frame sizes 100MM up o 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 direct current 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 . 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 . 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. Conditions: Motors of this series can continuously run at the rated power under the following conditions: ①Altitude: Above sea level , not exceeding 1000m . ②Ambient temperature: It varies with seasons but not exceeding +40℃. Voltage, Frequency and duty Frequency:50Hz,60Hz Rated Voltage:220V/380V,380V/660V Connection: Y-connection for 3kW and below whereas delta-connection for 4kW and above . Duty: Continuous(S1) Insulation class: B ,F Protection:IP44 , IP54 or IP55 NOTES: Imported bearing and locked bearing at D-end on request . |
