The series AEJ brake motor are totally enclosed fan-cooled three-phase. Squirrel-cage induction motors with DC disc electromagnetic brake. With rapid, braking simple construction, high reliability, excellent universal performance etc. There is a manual release set on the brake the motors are widely used in various machinery equipments and driving mechanisms. Which require braking and accurate position.
2、PRINCIPLE AND CONSTRUCTION
The DC disc brake of the series AEJ is mounted on the end-shield at non drive end while the motor is switched on, brake works at the same time, the motor begin to run because electromagnetic force attracts armature and passes the spring make disc separate from armature and end-shield when power supply is turned off iron core of the brake loses electromagnetic force, the armature is pulled by the spring to compress the brake disc. The motor is stopped at once by the force moment of frictions according to every type of AEJ series brake motors Relative double speed brake motors of AEJ series are available.
Brake's power is supplied by the rectifier in the terminal box,AC220V-DC99V for motor up to 3kw, AC380V-DC170V for 4kw and upwards.
