YEJ Series Electromagnetic Brake Three-phase Asynchronous Motor

Brief introduction and application range Y₂EJ series (IP54) electromagnetic brake three-phase asynchronous motor is derived from Y₂ series(IP54) three-phase asynchronous motor. The frame number is from 63 to 250, totally 12 frame numbers. The power range from 0.12 to 45 KW. Electrode number has 2.4.6.8 totally 68 specifications. This series motor's power grade, installation dimension, insulation grade, work mode, cooling mode and application condition are the same as Y₂ series. The performing standards is JB/T8680-2008 .This series motor is according to Q/HDJ01-2008 . Electromagnetic brake rated voltage:only frame size 71-100 are DC99V,112-200 are DC170V. Y₂EJ series motor mainly apply to stop quickly, locate to a nicely, reciprocating, frequently start, anti-sliding, such as lift machinery, transport machinery, color packing machinery, printing machinery, foodstuff machinery, construction machinery, carpenter machinery, reducing machinery, metallurgy machinery, forging machinery etc.

Y₂EJ series (IP54) electromagnetic brake three-phase asynchronous motor's feature and operation principle The stator and rotor of Y₂EJ series (IP54) electromagnetic brake three-phase asynchronous motor are general use of Y₂ series, the attached electromagnetic iron can be excited by direct current. While connect the three phase power source, the electromagnetic iron can get energy and occur the magnetic attraction to attract the armature so as to separate the friction surface of disk brake from the static friction sub-phase and then rotate under the action of magnetic torque, when cut off the electricity, the magnetic iron will also out of power and the attraction of magnet will also loss, then under the pressure of brake spring, the armature will contact the disk brake and occur the friction torque and in the final stop the motor. To change the stator position after the stop of motor, we can realize the motor stop by releasing device, the procedure is to rotate release screw. Two special sliding blocks and make the mutual displacement so as to separate the disk brake from the static friction sub-phase.
