YEJ series braking motors are total enclosed fan cool squirrel-cage
tri phase induction motors,it have an append braking disc,by dc
power .fast braking,simple structure,high stability.the brake has a
handede release structure(63-90 frame without this device),wide
applied to any transmission that need rapid stop,exact
positioning.the motors according with standard JB/T6456-1992,this
motors wide applied to layhe machine wood machine food processing
equipment chem engineering prcking machine textile machine
architectural machine gear reducer etc.
2.PRINCIPLE—STRUCTURE:
The DC braking disc append to non dirve endshiled of motor,when the
motor start while the DC current entry to coil of brake,the
magnetic core attract the armature and compress the spring the
braking disc and armature separate togather,the motor shaft rotate
free .when turn off the power of motor while electric magnetic
force is loss the spring is relax the braking disc and armature
contact each other,the motor are rapid stop.for frictional
torque.every mofel motor has a correspond DC rectifier, this
factory provide the YDEJ dual speed(multic speed far pole
ratio)motors.the brake power on terminal box of motor.up
