AZML series (power-loss type) three-phase AC electromagnetic brake is a reliable and safe brake. The product has compact structure, convenient manual release, flexible and reliable performance.
AZML series three-phase AC electromagnetic brake and Y2 series motor form YEJA series electromagnetic brake three-phase asynchronous motor. The motor has beautiful appearance, fast braking, accurate positioning, and is suitable for all occasions of motor use.
This series of products have obtained the certificate of ISO 9001 system.
When electrified, the electromagnet produces a strong electromagnetic force to suck the armature compression brake spring, and the two dual faces of the brake disc are separated from the pressure of the armature and the plane of the back cover of the motor, so the motor can rotate flexibly. When power is cut off, the brake spring pressure is applied to the armature to make it press the brake disc tightly and produce strong friction braking moment, so that the rotating motor brakes quickly and achieves accurate positioning.
1. Use three-phase AC power supply without AC/DC conversion.
2. After assembling with the motor, the overall protection level reaches IP55.
3. Manual release is external, 63-100 is handle, 112-180 is inner hexagonal screw, flexible and convenient;
4. The insulation grade is F.
Supplies of Matching Parts and Components
For the convenience of customers to use AZML series three-phase AC electromagnetic brake, our company not only provides matchable rear cover, brake mounting seat, junction box, brake shield and other accessories, but also provides the corresponding specifications of the rotor shaft processing drawings, as long as processed according to our company's drawings, YEJA series brake motor can be produced.
Note: Considering AZML132, 160, 180 spring force is too large. So manual release directly uses the inner hexagonal screw.
1. The structure sketch is as follows:
2. Requirements for Air Gap Value of Brake
3. Gap Inspection
As shown in the schematic diagram, the distance between armature 10 and electromagnet 14 is called air gap (delta). Normal working air gap (delta) does not exceed the specified maximum working air gap value. The motor is adjusted when it leaves the factory.After running for a period of time, the air gap (delta) increases due to friction wear, which will affect the normal suction and braking effect of the brake, so it will be used for a period of time in the motor.After that, the size of the plug must be selected according to the maximum air gap value, and the air gap size must be checked. When checking, plug ruler can be directly inserted into air gap (delta). If plug enters, it indicates that air gap is too large and must be entered.Line adjustment.
4. Air Gap Adjustment
Prepare a set of thick and thin plug rulers, select the thickness according to the initial working air gap value of the table above, release the nut 13, put the plug ruler into the clearance (delta) at the edge of the loosened screw, slowly screw in the locking nut 15, press.Tighten the plug ruler, then tighten the nut 13 outward and pull out the plug ruler. In the same way, the clearance between the second screw and the third screw is adjusted, and then the nut 13 and the locking nut 15 are tightened again after the clearance is adjusted.Check nut loosening regularly. There are six groups of brake screw above AZML132. According to the above method, three groups can be adjusted according to 120 degrees, and then another three groups. Three points of gap adjustment should be uniform.Otherwise, it will affect the brake suction and braking, and will burn the coil in serious cases. If there is no regular plug ruler, it can be replaced by similar thick and thin iron sheet.
adjustment.In normal working air gap, when the braking moment does not reach the rated braking moment, three nuts 12 (more than 132 seat number is six) can be uniformly screwed forward to compress the braking spring 11, which can be enlarged.Power moment, but not too much, as long as the rated braking moment on the nameplate can be achieved, too much spring pressure will cause difficulty in attracting, or emit ugly squeaky electromagnetic sound, serious will burn the coil.This spring force cannot be increased indefinitely.
|NO.||Fault phenomenon||Examination site and method||Solutions|
Brakes do not suck and have
severe vibration and squeaks.
|(1) Check whether nut 13 is loose;
(2) Measuring whether the air gap (delta) is larger
than the maximum working air gap;
(3) Measuring the resistance value of three-phase
winding with multimeter, whether it is basically
balanced, whether it is broken or not;
(4) Inspection of 500V AC Voltage of Multimeter
Whether the three-phase AC power supply is in
phase missing or not;
(5) excessive braking moment exceeding rated
(6) Check whether foreign bodies are stuck on the
surface of iron absorption or whether dry grease
deposits cause unevenness on the surface;
(7) The surface of iron absorption is uneven after
|(1) Tightening nut 13;
(2) Re-adjust the air gap (delta) to the initial working air gap;
(3) To repair or replace the magnetic strands with broken wires;
(4) Eliminate problems found;
(5) Adjusting the compression length of.the brake spring to control the braking moment;
(6) Removing foreign bodies and grease scale;
(7) Leveling by lathe or surface grinder;
|2||Brake failure and brake failure||(1) The brake disc wears and the air gap (delta)
increases and the moment decreases.
(2) Brake disc damage;
(3) Load inertia is too large to exceed braking moment.
|(1)Re-adjust the air gap and turn nut 4 into half circle to one circle;
(2)Replacement of new brake discs;
When released manually,
the rotating shaft does not move.
|(1) The brake disc is stuck with oil (from the gear-
box or elsewhere).
|(1) Remove the brake disc and wipe it dry before assembling it.|
