YEJ2 series electromagnetic-brake motors
Detailed Product 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'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. Conditions: Motors of this series can continuously run at the rated power under the following conditions: 1. Altitude: Ablve sea level, not exceeding 1000m. 2. Ambient temperature: It varies with seasons but not exceeding +40 degree. 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 requst. |
