YEJ Motor Features
YEJ series DC brake motors is a kind of totally enclosed fan-cooled squirrel-cage three phase asynchronous motors,it was designed accoring to IEC standsrd and has a lot of advantage including prompt braking,compact structure,high reliability,high efficirncy,energy saving,large startin 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 aviod 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 froce lost, the spring pushes the armature to the brake disc,the motor stops immediately,a braking action finished. The power of the brake 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.
