Product Brief

DZK series DC electromagnetic brake is a reliable and safe brake. The product has compact structure, convenient manual release, flexible and reliable performance.

DZK series brake and Y2 series motor form YEJK 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.

Working principle

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 power loss occurs, the armature plate is pressurized by the brake spring pressure to tighten the brake disc and generate a strong friction braking moment, so that the rotating motor brakes rapidly and achieves accurate positioning.

Product characteristics

1. The overall protection level reaches IP23.

2. Manual release is an external handle, which is flexible and convenient.

3. The insulation grade is F.

Supplies of Matching Parts and Components

For the convenience of customers to use DZMF series DC electromagnetic brake, our company not only provides matchable rear cover, junction box, windshield and other 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 YEJF 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 the armature plate 10 and the electromagnet 16 is called the air gap (delta).Normal working air gap (delta) does not exceed the specified maximum working air gap value. When the motor 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 is used in the motor. After a period of time, 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 checking, plug ruler can be directly inserted into air gap (delta). If it is inserted, air gap can be explained.(delta) is too large and must be adjusted.

4. Air Gap Adjustment

Choose the thickness of the plug ruler according to the specified initial working air gap value, loosen the inner hexagonal screw 16, and rotate the support adjusting screw sleeve 1 to 1-2 mm in the direction of the electromagnet to facilitate air gap adjustment. The size of the plug will be selected.The ruler is placed in the air gap (delta) next to the support adjusting bolt. Slowly, the inner hexagonal screw 16 is screwed in and the plug ruler is pressed. Then, the support adjusting screw sleeve 1 is tightened to the top cover 8 planes and the plug ruler is pulled out. DZK04-75 Fixation There are three groups of inner hexagonal screw 16. 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. Finally, the inner hexagonal screw should be tightened. 16. There are four groups of internal hexagonal screw 16 for DZK150 fixation, and the debugging method is the same as that mentioned above.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.

NO.	Fault phenomenon	Examination site and method	Solutions
1	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 value;	(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;
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; (3)Re-selection.
3	When released manually, the rotating shaft does not move.	(1) The air gap is uneven, and the armature, brake disc and electromagnet are stuck (2) The friction disc is stuck with oil (from the gearbox or elsewhere). (3) The brake is not used for a long time, and the flat friction plate of the motor end cover is rusty.	(1) Re-adjust the air gap; (2) Disassemble and remove the friction plate, dry it before assembling. (3) After disassembling, remove the rust spots and reassemble it, then it can work normally.
