Electromagnetic brakes are increasingly used in modern industry. Their mechanical transmission system mainly controls movement and transmits power. It is a very ideal automatic actuator. Electromagnetic brakes are widely used in construction, machine tools, ships and other industries. Electromagnetic brakes play a role in controlling and transmitting motion in machinery.

　　 Electromagnetic brake Its applications in modern industry are increasingly widespread. Its mechanical transmission system mainly plays a role in controlling movement and transmitting power. It is a very ideal automatic actuator. Electromagnetic brakes are widely used in construction, machine tools, ships and other industries. Electromagnetic brakes play a role in controlling and transmitting movement in machinery.

　　With the continuous advancement of technology, all walks of life have also made great progress, and the development prospects of brakes are also very good. The demand is constantly increasing, and there are many brake suppliers on the market. As manufacturers, we also need to tell you some small knowledge points about electromagnetic brakes here. Interested friends can take a look together.

       

　　Before using an electromagnetic brake, everyone has many questions, so if you want to use it better, you should understand some of its knowledge points. The brake is one of the frequently operating components in an elevator. It can stop the elevator motor without power, effectively stopping the car. The safe operation of the elevator is closely related to the working state of the brake. Therefore, a large number of accident cases show that one of the main reasons for elevator personal injury accidents is brake failure or design defects, leading to elevator bumps, reversals, sliding, or even shearing. Therefore, strengthening the safety inspection of elevator brakes is particularly important. Electromagnetic brake suppliers suggest that it should be noted that the travel indicator collides with the activity indicator during use. Some manufacturers' designers have not carefully considered the uniqueness of the travel indicator installation. Long-term use will cause the brake pads to fall off and stick. Electromagnetic brake suppliers believe that attention should be paid to the aging and cracking of the sealing rubber, the dropping of foreign objects, causing the brake to jam. The electromagnetic core rusts, causing the brake to jam. The elevator iron core guiding mechanism is not reasonably designed, and multiple fractures occur at the connection between the copper strip and the iron core, causing the brake to jam.

　　Electromagnetic brake suppliers suggest that attention should be paid to generating sufficient braking torque so that when the elevator power supply or control circuit power supply is lost for any reason, the car can stop reliably. Therefore, braking torque is its main parameter. Of course, it is mainly used to ensure that the elevator in operation stops at the deceleration required by the standard. If you are using it, you should check the process by turning off the main power switch and checking whether the vehicle is braking, deformed, and damaged when the vehicle is unloaded and moving upwards at normal operating speed to the upper part of the stroke. The supplier reminds everyone to carry 125% of the rated load and descend at normal running speed. When the car runs to the lower stop station, cut off the motor power, brake, and the car should stop reliably without obvious deformation and damage. Generally, an acceleration and deceleration tester is used for on-site testing and recording of numerical values, and the instrument can display the average deceleration. The supplier's products have a compact structure and reasonable design.

　　After the above Electromagnetic brake introduction, I hope it will be helpful to you.
