What is the reason for the short service life of electromagnetic brakes?
Release time:
2022-08-08
The reason for the short service life of the electromagnetic brake is directly related to the manufacturing material, working environment, maintenance, load weight and surface temperature of the electromagnetic clutch itself. The quality of the materials used by the electromagnetic clutch manufacturer directly affects the quality and service life of the electromagnetic clutch.
The reason for the short service life of the electromagnetic brake is directly related to the manufacturing material, working environment, maintenance, load weight and surface temperature of the electromagnetic clutch itself. The quality of the materials used by the electromagnetic clutch manufacturer directly affects the quality and service life of the electromagnetic clutch. In addition, you must pay attention to the humidity of the place or whether there is a lot of dust during use. Maintenance is one of the daily tasks of all equipment. Whether the electromagnetic clutch works normally and whether there are safety hazards will indirectly affect production and cost.
How to choose the size of the electromagnetic clutch model is one of the most important issues for electromagnetic clutch users. The torque of the large model is large, and the torque of the small model is small. The torque of the electromagnetic clutch will also directly affect the operation of the machine. Whether the torque is sufficient to carry the weight depends on the torque of the electromagnetic clutch itself. Electromagnetic clutch is divided into power combination and power combination. The electromagnetic clutch of these two combinations will produce friction during operation. If there is friction, there will be temperature. The longer the working time of the electromagnetic clutch, the higher the friction temperature. The higher the temperature, the greater the wear of the electromagnetic clutch working surface. This is also one of the important factors affecting the service life of electromagnetic brakes, which cannot be ignored. The electromagnetic brake is the same product as the electromagnetic clutch, and should be paid attention to during use.
Precautions during installation of electromagnetic brake:
1. The electromagnetic brake and the motor share the power supply. It must be ensured that the motor and brake are powered and de-powered at the same time.
Considering the characteristics of simultaneous power supply and power loss, the consistency of the rated voltage of the two must be guaranteed.
3. The electromagnetic brake can only lose power and release the brake control under the rated voltage. Once the voltage is too low, the motor cannot be started, and the motor will be burned; therefore, the motor with brake must be started under full pressure.
4. During the short-circuit test of the motor, due to the low pressure (such as 380V three-phase asynchronous motor, the pressure is generally 100V), the motor can meet the static requirements without stalling.
5. The brake disc gap is generally adjusted before leaving the factory. After the brake is installed, the clearance compliance shall be verified and confirmed by inspection and testing.
6. The brake wiring should be reliable, and its terminals should be installed under the motor wiring fixing nut together with the motor stator terminals to ensure that the customer's wiring will not affect its original wiring reliability.
Analysis of the causes of electromagnetic brake failure:
1. The brake cannot be relieved after power on: possible reasons include damage to the coil; the power supply is not connected or the voltage is insufficient; the working gap is too large to be closed.
2. Insufficient braking torque: the motor speed is too high; the motor load is too large; the friction surface is contaminated or damaged; the spring force is insufficient or invalid.
3, electromagnetic brake heating: friction plate overload slip; power supply voltage is insufficient.

The role of electromagnetic brake
2022-10-28
Regarding the difference between energized brakes and non-energized electromagnetic brakes, many users do not know the working principle of these two electromagnetic brakes and the difference between the two. Then, let's learn about the role of electromagnetic brakes!
Introduction and Application of Electromagnetic Brake
2022-10-18
Electromagnetic brakes are mainly matched with series motors and are widely used in the metallurgical industry. Construction. The chemical industry. Food. Machine tools. Phase. The elevator. Vessels. Packaging machinery and braking in the event of electrical failure.
The working principle of electromagnetic brake
2022-10-09
The electromagnetic brake is a connector that transmits torque from the active side to the passive side. Any combination of cutting or braking can be required. The electromagnetic brake has compact structure, simple operation, sensitive response and easy to realize remote control.
The company has a product research and development department composed of experts, senior engineers and other professional and technical personnel. It is engaged in research and development and has perfect research and development test equipment. At present, the products reach more than 100 series of nearly 1,000 specifications, and the force distance ranges from 0.1N. m ~ 250000N.m. The company has been rated as a high-tech enterprise by the state for more than ten consecutive years, and a number of R & D projects have been established locally and have received municipal financial support.
