Overview Of MQAEJ/QAEJ Brake Motor:
The MQAEJ/QAEJ series electromagnetic brake three-phase asynchronous motor is a derivative of the M2QA series motor structure, with an additional electromagnetic brake. The motor is suitable for various equipment or automatic assembly lines with power-off braking and positioning requirements. MQAEJ and QAEJ series electromagnetic brake three-phase asynchronous motors are updated products that replace the MYUEJ and YUEJ series. Its structure is composed of QA series motor and electromagnetic brake. It is an ideal drive device for industrial modernization because it has the advantages of large power range, simple structure, low noise, short braking time, reliable braking performance, and the same installation dimensions (except total length) as the basic series. It is an ideal driving device in industrial modernization and is widely used in woodworking machinery, gear reduction and various metal cutting machine tools, light industrial production lines, textile machinery, chemical machinery, construction industries, etc.

3. Reasonable structural design
Structure and Principle
The DC disc brake of MQAEJ and QAEJ series electromagnetic brake three-phase asynchronous motors is installed on the end cover of the non-shaft extension end of the motor. The working principle is: When the motor is connected to the power supply, the rectifier of the brake is connected to the power supply at the same time. Due to the electromagnetic attraction, the electromagnet attracts the armature and compresses the spring. The brake disc is detached from the armature and the end cover, and the motor runs. When the power supply is cut off, the electromagnet attracts the armature and compresses the spring. , the brake electromagnet loses its electromagnetic attraction, and the spring force pushes the armature to press the brake disc. Under the action of friction torque, the motor stops rotating immediately. The excitation voltage of the electromagnetic brake is 205 volts DC, and the power supply of the rectifier is 220 volts AC.
Flexible pinout direction
The motor junction box can be installed on the top, left or right side of the motor. The junction box itself can be rotated and installed. The junction box of the 71-132 base can be rotated in 4*90 directions. The junction box of base 160 and above can be rotated in 2*180 directions. Users must indicate the direction of the junction box and outlet holes when ordering.
Beautiful motor shape
The heat dissipation ribs of the machine base are designed to be distributed vertically and horizontally. The end caps, junction boxes, and air hoods are all newly designed, with a unique and beautiful appearance.
