YEJ series DC brake motors is a kind of totally enclosed fan-cooled
squirrel-cage three phase asynchronous motors, it was designed
according to IC standard and has a lot of advantages including
prompt braking, compact structure, high reliability, high
efficiency, energy saving, large starting torque, easy operation &
servicing etc. Besides, the brake has a manual release device,
which allows the brake a junction of both manual release and
electric release and is convenient for operation. YEJ series DC
brake motors are suitable for mechanism that requires prompt
braking, accurate positioning, repeat running, frequent starting
and avoid slipping. Principle and structure of the brake motors,
the DC brake disc is assembled on the non-drive end shaft of the
motor, when supplied with power, the brake works simultaneously,
the electromagnetic force attracts the armature and presses the
spring, thus the brake disc is released from armature and
endshield, then the motor begins to run; When the power supply is
cut off, electromagnetic force lost, the spring pushes the armature
to the brake disc, the motor stops immediately, a braking action
finished. The power of the brakt is supplied by rectifier fixed in
the terminal box, DC 99V for motors up to 3KW and DC 170V for
motors 4KW and up. Y2EJ series DC brake motors (DC brake assembled
on Y2 series motors) and YDEJ series DC brake motors (DC brake
assembled on YD series multi-speed motors) are also available.
