The dry electromagnetic brake generates magnetic force when the coil is energized, and absorbs the "armature" piece. The brake is in the engaged state. When the coil power is cut off, the "armature" rebounds and the brake is disconnected. Electromagnetic brakes and brake motors are generally used in the range of ambient temperature of minus 20°C to 50°C and humidity of 85 percent. In a medium without explosion hazard, the variation of the coil voltage does not exceed 5 percent of the rated voltage.
Features of dry electromagnetic brake

1. High-speed response. Because it is a dry type, the torque is transmitted quickly and can be moved easily.　　

2. Strong durability. The heat dissipation condition is good, and the material is used, even if high frequency and high energy are used, it is durable enough.

3. Easy to assemble and maintain. Because it is a static magnetic field coil with a built-in ball bearing, there is no need to remove the chassis or use carbon brushes, making it easy to use.　　

4. Reliable action. Using plate-shaped shrapnel, it will not loosen even if there is strong vibration, and it has good durability. To
Precautions for use of dry electromagnetic brake

1. Do not add grease when using dry electromagnetic brakes, otherwise the torque may decrease.　　

2. Clean before installing the electromagnetic brake, remove anti-rust grease and garbage.　　

3. The electromagnetic brake can be installed coaxially or on the shaft and fixed axially. When installed on the shaft, the coaxiality between the shafts of the driving part and the driven part is below 0.1mm.　　

4. When the wet electromagnetic brake is working, add lubricating oil between the friction plates, and the lubrication method is divided into lubrication. The part immersed in oil is 5 times the volume of the brake. The shaft supply lubrication adopts the shaft supply method when working at high speed and high frequency.

5. When installing the claw type electromagnetic brake, ensure a certain gap between the end face teeth, and do not have the phenomenon of no teeth grinding when idling.　　

6. The electromagnetic brake and the brake are insulated with class b, and the normal temperature rises by 40℃. The operating temperature during thermal equilibrium shall not exceed 100°C. Otherwise, the ring and the friction part are easily damaged.　　

7. The power supply, control line and brake power supply are generally DC 24V. Three-phase or single-phase AC voltage is obtained by step-down and full-wave rectification. There is no requirement for stability and filtering. The power supply is more than 1.5 times the rated power of the electromagnetic separator. A half-wave rectification power supply should be used to install a return diode.
