DZM series DC electromagnetic brake is a reliable and safe brake. The product has compact structure, convenient and flexible manual release, reliable performance, low noise, and IP44 protection level. It can effectively prevent dust, iron powder and iron scraps.
DZM series brake and Y2 series motor form YEJ 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 strong electromagnetic force to suck up the armature plate to compress the brake spring. The two dual faces of the brake disc are separated from the pressure of the armature plate and the plane of the back cover of the motor, and the motor can rotate flexibly. When the power is cut off, the brake spring pressure is applied to the armature plate to tighten the brake disc and produce strong friction braking moment, which makes the rotating motor brake quickly and achieve accurate positioning.
1. After assembling this series of products and motors, the overall protection level reaches IP44, which is higher than the requirements of JB/T6456 industry standard.
2. The braking moment is higher than the requirement of JB/T6456 industry standard.
3. Manual release external device, flexible and convenient (DZM02 without manual release);
4. The insulation grade is F.
Supplies of Matching Parts and Components
For the convenience of customers to use DZM series DC electromagnetic brake, our company not only provides matchable rear cover, junction box, windshield, rectifier and sealing ring accessories, but also provides the corresponding specifications of the rotor shaft processing drawings, as long as processing according to our company's drawings, you can produce YEJ series brake motor.
As shown in the schematic diagram, the distance between armature plate 7 and electromagnet 9 is called air gap (δ). Normal working
airgap(δ) does not exceed the specified maximumworking air gap value. When the motor leaves the factory, it is adjusted toIn the
initial working air gap range, after running for a period of time, the air gap (δ) increases due to wear of friction pads, which will affect
the normal suction and brakingeffect of the brake, so the motor will be used for a period of time.After that, the size of plug must be selected
according to the maximum air gap value, and the size of air gap (δ) must be checked. When inspecting, the selected size of the plug ruler
can bedirectly inserted into the air gap (δ), such as the plug.The air gap (δ) is too large and must be adjusted.
DZM02-80 adjustment method: as shown in the structure sketch, the thickness of plug gauge is selected according to the specified initial
working air gap value, the hexagonal nut 23 is loosened, the inner hexagonal screw 26 is loosened, and the expenditure support adjustment
screw is loosened.24. Choose the size of the plug ruler and insert it into the air gap (delta) next to the loosened support adjusting screw 24.
Slowly screw in the inner hexagonal screw 26, press the plug ruler, and then tighten the support adjusting screw 24.End cover 2 plane, pull out
plug ruler. Fixed screw 26 has three groups. The air gap values on the edges of the three groups of screw must be adjusted to the initial working
air gap values according to the above methods. The air gap values at the three places must be uniform and the best.Back screw
nut 23.DZM160-900 adjustment method: as shown in the structure sketch, the thickness of plug gauge is selected according to the specified
initial working air gap value, the fixed screw 26 is loosened, the adjusting screw sleeve 18 is loosened, and the plug gauge is put in.In the air
gap (delta) next to the adjusting screw sleeve 18, slowly screw in the inner hexagonal screw 26, press the plug ruler, then tighten the top cover
2 plane of the supporting adjusting screw sleeve 18, and pull out the plug ruler. Inner six angle snail There are six groups of screw 26. The air
gap on the edge of three groups of fixed screw with equal 120 degrees must be adjusted to the initial working air gap value according to the
above method. The air gap value in three places must be uniform, and then the other three groups of fixed screw must be adjusted.
The air gap (delta) next to the screw, and tighten the inner hexagonal screw 26 and the support adjustment screw 18. The adjusted air gap
should be checked again with a plug ruler to prevent the unevenness of the air gap. No air gap adjustment There are standard plug rulers,
which can be replaced by similar thick and thin iron sheet.
