AZM-B series (power-off brake type) three-phase AC brakes are reliable safety brakes. They feature fast start-up time and short braking time. The excitation voltage is the same as that of the motor, making wiring simple and operation convenient.

The AZM-B series three-phase AC brakes have a compact product structure, and their braking torque and air gap adjustment are very convenient. The manual release device has a dual function: a gentle pull on the release ring temporarily disengages the brake. By screwing in the release screw, the brake can be permanently disengaged, offering light and reliable operation. The protection level of this product can reach IP55.

The AZM-B series three-phase AC brakes can be directly used with variable frequency power supplies. For frequencies below 50Hz, variable frequency power supplies can be used directly; if required, they can be designed for frequencies above 50Hz.

The AZM-B series three-phase AC brakes fully meet the requirements for forming YEJ series electromagnetic braking three-phase asynchronous motors when paired with Y and Y2 series motors, and can also be paired with variable frequency motors to form variable frequency braking motors. With their advantages of large braking torque, short braking time, convenient wiring, and high protection level, they can be widely used in various mechanical equipment requiring rapid braking and precise positioning.

Working Principle:

The AZM-B series three-phase AC brakes operate as follows: when power is cut off, they use spring pressure to tightly press the armature, generating huge friction (braking) torque between the brake disc and both sides of the armature and the motor's rear end cover, allowing rotating objects to brake quickly. When powered on, they use the electromagnetic attraction and release principle to disengage the brake disc from the braking state, allowing the object to rotate freely.

Air gap adjustment method:
Tools: Wrench, feeler gauge
Adjustment method: Unscrew nuts and screws (14) (15), remove the cover (12), loosen 6 nuts (9) (10), select the working air gap thickness sheet according to the model of the feeler gauge, insert it near one of the fixing screws (3) δ point, screw in (10) to press the insert, then slightly retract a little, the feeler gauge can be removed, it cannot be too loose. Then, the locking nut (9) must be tightened. Use the same method to adjust the other two points 120° apart. Finally, check again whether the air gaps are the same. If they are too tight or too loose, they need to be adjusted to ensure that the three points are uniform. After long-term work, the friction pads will wear out. The δ value must be checked. If the δ value exceeds the maximum wear air gap value, it must be adjusted using the above method, otherwise it will affect the normal operation of the brake.

Precautions:
1. The armature, rear cover, and brake disc surface must be free of oil and kept dry and clean;
2. During installation and adjustment, the air gap "δ" value must be within the working air gap range;
3. The spline sleeve must not have axial movement, and a retaining ring must be added to the rear end of the spline. When assembling the brake disc, apply an appropriate amount of grease to the spline teeth.
