MQAEJ, QAEJ series of electromagnetic braking three-phase asynchronous motor is a substitute to replace the MYUEJ and YUEJ series of updates.The structure of QA series motor and electromagnetic brake assembly. It is a kind of industrial modernization drive device, because it has a large power range, simple structure, low noise, short braking time, braking performance and reliable installation dimensions (except outside the length) and basic series of the same advantages, widely used in woodworking machinery, gear reducer and all kinds of metal cutting machine tool, light industry production line, textile machinery, chemical machinery, construction industry, etc.
1, the motor in accordance with the following criteria
The International Electrotechnical Commission IEC34, IEC72
Australian standard AS1359-2
The British standard BS4999-5000
German standard DIN42673
In accordance with the "CE" marking requirements
The motor (IDT IEC 60034-1) with GB755, GB10069 (NEQ IEC 60034-9), Q/JBQS28
2, the superior performance of the motor with low noise and low vibration
By optimizing design and technology, MQAEJ, QAEJ series motor has greatly reduced the noise and vibration, and reached the international advanced level.
The high level of protection performance
The standard design of motor protection class is IP55, can provide higher levels of protection are required according to customer requirements.


The high level of protection performance
The standard design of motor protection class is IP55, can provide higher levels of protection are required according to customer requirements. To improve the insulation level, increase the service life of the motor, the motor adopts standard F class insulation structure, thereby improving the service life of the motor, increase the reliability of the electric motor.

high efficiency
The optimization design of motor, with high efficiency, can produce considerable energy saving.

3, reasonable structure design
The structure and principle
MQAEJ, QAEJ series of electromagnetic braking three-phase asynchronous motor, the DC brake disc is installed in the motor shaft extension end of the end cover. The working principle is: when the motor power, brake rectifier and the power supply is switched on, the electromagnetic suction, attracts the armature and the compression spring, brake disc and armature end cover, disengaged from the motor operation, when the power is turned off, the brake electromagnet loses electromagnetic force, spring force pushes the armature to the brake disc, the friction torque under the action of the motor stop rotating immediately. The excitation voltage of the electromagnetic brake is 205 volt DC power rectifier, AC 220 volts.


Flexible lead direction
Installation of the motor terminal box on top of the motor, left and right, the terminal boxes can be mounted for rotation, a rotatable connection box 71-132 4*90 direction. 160 and above the base terminal box can rotate in 2*180 direction. The user must indicate the junction box and the outlet hole direction in order.

The appearance of the motor
A radiating rib design into the vertical and horizontal distribution, end cover, junction box, hood was a new design, beautiful and unique appearance.

4, many choose to meet the various needs of the user
