Electriomagnetic brake electric motor

Be specially designed for special requirement, which confirms to JB/T6428-92 and IEC standard.

It is totally enclosed and fan-cooled motor with DC electromagnetic brake disc.

With the feature of reliable braking, regulated braking torque, rotor without axial channeling move, convenient operation and maintenance.

Brake disc is installed in the end cover at non-driving side. When supply the power to brake motor, brake also work at the same time. Due to the electromagnetic suction function, electromagnet attracts armature and compression spring, brake disc separate from armature, end cover, the motor start working.

When cut off power supply, brake electromagnet lose the electromagnetic suction, spring driven armature to pressure brake disc. Under the effect of friction torque, the motor stop working immediately.

The voltage of electromagnetic brake is as following:

DC 99V for YEJ brake motor power is less than 4kW

DC 170V for YEJ brake power is 4kW and above

Equipped with re-greasing system when the motor frame size is 160MM and above

YEJ brake electric motor is widely used for machinery that request rapid braking, accurate positioning, reciprocating motion, frequent starting and braking, as the main drive and auxiliary transmission.

For example, electric valve, rubber chemical machinery, metal processing machine tools, packaging machinery, woodworking machinery, food machinery, chemical machinery, textile machinery, construction machinery, gear reducer, etc.

Labeling Standards

Series Code + Frame Size + Iron Core Length No. + Motor Poles

Example: YEJ 90 L – 2

YEJ—means electromagnetic brake electric motor

90—the second part means the height of motor center (when the motor has no foot, it is same to motor with foot)

L—the third part means the base iron core length no.(S-Short Base, M-Medium Base, L-Long Base)

2—the forth part means the motor poles, this is a 2 poles motor, synchronous speed is 3000 r/min (50Hz); 3600 r/min (60Hz)
