3.电机结构设计结构与原理
--MQAEJ、QAEJ系列电磁制动三相异步电动机，其直流圆盘制动器安装在电动机非轴伸端的端盖上。
电机工作原理是：当电机接入电源时，制动器的整流器同时接通电源，由于电磁吸力作用，电磁铁吸引衔铁并压缩弹簧，制动盘与衔铁、端盖脱开，电机运转，当切断电源时，制动器电磁铁失去电磁吸力，弹簧力推动衔铁压紧制动盘，在摩擦力矩的作用下，电机立即停止转动。电磁制动器的励磁电压为直流205伏，整流器电源为交流220伏。灵活的引出线方向--电机接线盒的安装方式可在电机顶部、左侧、右侧,接线盒自身可旋转安装,71-132机座的接线盒可旋转4*90方向。160及以上机座接线盒可旋转2*180方向。用户在订货时必须标明接线盒及出线孔方向。美观的电机造型--机座散热筋设计成垂直、水平分布,端盖、接线盒、风罩均为全新设计,外形别致美观。

Mechanical Design
1.Construction and Principle
The Dc disk-brake of the MQAE,QAEJ series motors is mounted on the endshield at the nondrive end. The principle for the brake is when power is on, the electromagnetic brake starts up. By the action of electromagnetic force,the iron core attracts the armature and compresses the spring,when the brake disk is separated from the armature and end shield,the otor begins to run .When power is off, the iron core of the brake loses electromagnetic force,when the armature is pulled by the spring to compress the brake disk ,the motor is stopped at once by the moment of fraction .Rated voltage of the electromagnetic brake is 205V(DC).Supply voltage of the rectifier si 220v(AC).
2.Thrminal boxes
Thrminal boxes are mounted either on the top ,or on either side of the motor The terminal box of motors sizes 71 to 132 can be turned 4*90' and in motors sizes 160*225rotated 2*180'.To enable the supply of suitable terminations for the motor ,please state cable type ,quantity and size when ordering.
3.Polished outward appearance
The external design of the motors is consistent wiht the design of the ABB"M2000"family.The frame,cooling ribs,terminal box and fan cover have been reshaped to meet customer's design preference.
