Product Brief

DZMF series (electrified) DC electromagnetic brake is an electrified brake. The product features compact structure, reliable performance, convenient installation and adjustment, large braking moment and long service life.

DZMF series DC electromagnetic brake and Y2 series motor form YEJF series electromagnetic brake three-phase asynchronous motor. The motor has beautiful appearance, fast braking and accurate positioning. By means of automatic control, special braking functions are realized and applied to various transmission machinery.


Working principle

Take the motor as an example, when the motor works, the brake is not working. When the motor stops working, the brake will be energized. At this time, the electromagnet produces strong electromagnetic force, overcomes the tension of the reset spring steel sheet, sucks the friction plate, contacts with the friction sheet, and generates friction moment, so that the rotating parts brake quickly and achieve accurate positioning. When power loss occurs, the friction plate is restored to its original position by resetting the tension of the spring steel sheet. At this time, the rotating parts are free from the restraint of the friction braking moment, and the motor shaft can rotate freely.


Product characteristics

1. The overall protection level reaches IP23.

2. The cooling mode of brake is self-cooling.

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.

Corresponding parameter set not found, please add it in property template of background

1. The schematic drawings of each specification are 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 electromagnet 5 and the friction plate 7 is called the air gap (delta). Normal


working air gap (delta) does not exceed the prescribed maximum air gap value. The motor is adjusted when it leaves the factory

In the initial working air gap range, 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 air gap (delta) must be checked by selecting the plug ruler according to the maximum air gap value. When inspecting,

the selected size of the plug ruler can be directly inserted into the air gap (delta). If it is inserted, it indicates that the air gap has passed.

Great, it must be adjusted
