DZM series DC electromagnetic brake is a reliable and safe brake. The product has compact structure, convenient manual release, flexible, 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.
1. The structure sketch is as follows:
2.Requirements for Air Gap Value of Brake
3. Inspection of air gap
As shown in the schematic diagram, the distance between armature plate 7 and electromagnet 9 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 plug must be selected according to the maximum air gap value, and the size of air gap (delta) must be checked.
When inspecting, the selected size of the plug ruler can be directly inserted into the air gap (delta), if it is inserted, indicating the air gap
(delta) is too large and must be adjusted.
4. Air Gap Adjustment
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 hexagon screw 26, press the plug ruler, and then tighten the top of the support adjusting screw 24.
Cover 2 plane, pull out the 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 three places must be
uniform and tightened finally.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 into the loosened position.
Expenditure support adjustment screw 18 next to the air gap (delta), slowly into the hexagonal screw 26, tighten the plug ruler, and then
support adjustment screw 18 top cover 2 plane, pull out the plug ruler. Internal hexagonal screw 26 has
Six groups, according to the above method, the air gap on the edge of three sets of fixed screw divided 120 degrees must be adjusted
to the initial working air gap value. The three air gap values must be uniform, and then the other three groups of fixed screw should be
adjusted next to each other.
The air gap (delta) is tightened and the inner hexagonal screw 26 and the support adjusting screw sleeve 18 are tightened.
The adjusted air gap should be checked again with a plug ruler to prevent the unevenness of the air gap. If there is no standard plug
gauge for air gap adjustment, it can be replaced by similar thick and thin iron sheet.
