What is the application range of electromagnetic power loss brake?
Release time:
2021-11-08
The electromagnetic power-off brake is also called the application range of the power-off brake. Its electromagnetic force attracts the armature to separate the armature from the brake disc (release). At this time, the drive shaft runs or starts normally with the brake disc. When the driveline is disengaged or de-energized, the brakes are also de-energized. At this time, the spring compresses the armature, forcing the brake disc, the armature and the flange to generate friction torque, and quickly stop the drive shaft.

When the driveline is disengaged or de-energized, the brakes are also de-energized. At this time, the spring compresses the armature, forcing the brake disc, the armature and the flange to generate friction torque, and quickly stop the drive shaft.
Attention must be paid to the scope of application of electromagnetic power loss brake: a. the surrounding medium is free of explosion hazard, gas and conductive dust sufficient to corrode metal and damage insulation; B. the working environment temperature is -40~+150 ℃, the friction plate and armature surface shall be free of oil stain and must be kept clean; C. insulation grade is grade B, protection grade is IP23, and voltage fluctuation range shall not exceed + 5% and-15%;D. The working air gap must not exceed the working air gap. The driving side and driven side of the brake shall be fixed without axial movement.
The application range of electromagnetic power-off brake: simple and compact structure, low heat, low noise, simple installation, wide adaptability, low noise, high action frequency, sensitive action, reliable and fast braking. It is suitable for metal processing, machine tools, packaging, construction, chemical industry, food, stage, elevator, ship and other systems, as well as power failure braking (risk prevention), precise positioning, safety braking, etc.
Precautions when using electromagnetic power-off brake
1. Foreign matter: The friction surface shall not be mixed with other foreign matter. The mixing of the grease will cause the friction plate to slip, rapidly reducing the friction generated, resulting in a sharp decline in the braking effect. The mixture of dust and metal particles can wear and damage the friction plates or rotating parts. Mixing of chemicals can cause rust and corrosion. Therefore, the brake needs to be protected during operation. If necessary, use protective covers to protect against oil, dust and corrosion. Increase the service life of the brake.
2. Humidity and water droplets: In the case of high relative humidity, if water droplets are attached to the friction surface of the electromagnetic brake and the electromagnetic clutch, low friction will appear before it is completely dry. Moisture is the main cause of corrosion of the electromagnetic brake. Please give your full attention.
3. Ventilation: As the friction heat generated by the electromagnetic brake and the electromagnetic clutch will radiate outside, it should be installed in a ventilated place. When used in places with poor ventilation and heat dissipation, please pay attention to the two items, and use forced air cooling when necessary.
4. Higher speed: larger allowable speed of electromagnetic brake and electromagnetic clutch. The greater speed is determined by the greater speed of the friction surface. If the speed is exceeded, the rated torque will not be produced, and abnormal wear or overheating deformation will occur.
5. Temperature: The electromagnetic brake and electromagnetic clutch are Class B insulation, the normal temperature rise is 40 ℃, and the working temperature during extreme thermal equilibrium is not allowed to exceed 100 ℃, otherwise the coil and friction parts are easily damaged.

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.
