YEJ series motors are composed of Y2 motors and additional AC brakes. YEJ series brake motors are equipped with electromagnetic brakes at the end of the motor's driving shaft. The friction braking torque makes the motor stop, and the no-load braking time is random from small to large, which is 0.15~0.45S. The brake power supply must be synchronized with the main power supply of the driving motor. Comply with IEC standard and have good interchangeability with similar foreign products. The AC brake of YEJ series motor is directly powered by three-phase 380V power supply. The AC brake not only has fast braking speed, but also has no secondary rectifier tube, thus greatly improving the reliability and service life of the motor.


Two major advantages / outstanding features of YEJ series:

AC brake Powered directly by 380V 50HZ without diodes, stable performance

Fast braking: The response speed of power-off braking is 0.08 seconds, which is several times faster than DC plane brakes
