AZM-B series brake_Taizhou Taili Explosion Proof Motor Co., Ltd.

AZM-B series (power-off brake type) three-phase AC brake is a reliable and safe brake. It has the characteristics of fast starting time and short braking time. The excitation voltage is the same as that of the motor, with simple wiring and convenient operation.

The AZM-B series of three-phase AC brakes have a compact structure and convenient adjustment of braking torque and air gap. The manual release device has a dual function. The brake can be temporarily released from the braking state with a slight pull of the release ring. With the screw-in release screw method, the brake can be released for a long time, and the operation is light and reliable. The product protection level can reach IP55.

AZM-B series three-phase AC brake can be directly used for variable frequency power supply. Frequency conversion power supply can be used directly for frequencies below 50Hz, and can be designed for frequencies above 50Hz if required.

AZM-B series three-phase AC brakes are fully compatible with Y and Y2 series motors to form YEJ series electromagnetic brake three-phase asynchronous motors, and can also be matched with variable frequency motors to form variable frequency brake motors. Utilizing its advantages such as large braking torque, short braking time, convenient wiring, high protection level, etc., it can be widely used in various mechanical equipment requiring fast braking and precise positioning.

Air gap debugging method:
Tools: mechanical hand, feeler gauge
Debugging method: unscrew (14) (15) nuts and screws, remove the guard (12), loosen (9) (10) 6 nuts, select the feeler gauge according to the model of the working air gap thickness slice, and insert 1 Only fix the δ point of the screw (3), screw in (10) to press the insert, and then withdraw it a little bit, so that the feeler gauge can be taken out, and it should not be too loose. Then you must tighten the nut (9), and use the same method to debug another 2 points that are 120° apart. Finally, check whether the air gap is the same. If it is too tight or too loose, it needs to be adjusted and the three points are even. After the friction plate has been worn for a long time, the δ value must be checked. When the “δ” value exceeds the maximum wear air gap value, the above method must be used for adjustment, otherwise it will affect the normal operation of the brake.To

Precautions:
1. There should be no oil stains on the surface of the armature, rear cover, and brake disc, and keep them dry and clean;
2. When installing and debugging, you must ensure that the air gap "δ" value is within the working air gap range;
3. The spline sleeve must not move axially, and a circlip must be added to the back end of the spline. When assembling the brake disc, apply a proper amount of butter to the spline teeth.
