1. Humidity and water droplets
If the friction surfaces of electromagnetic brakes and electromagnetic clutches have high relative humidity, there will be a phenomenon of low friction before they are completely dry, and moisture is the main cause of corrosion of electromagnetic brakes, please pay full attention.
Second, foreign objects
There must be no other foreign matter on the friction surface. The mixing of grease will cause the friction plate to slip, and the rapid reduction of the friction force will cause the braking effect to drop sharply. The mixing of dust and metal particles will cause the friction plate or the rotating part to wear and damage. The mixing of chemicals can cause rust and corrosion. Therefore, the brake needs to be protected during operation. If necessary, use a protective cover to achieve the effects of anti-oil, anti-dust and anti-corrosion. Enhance the service life of the brake.
Three, high speed
The high allowable speed of the electromagnetic brake and electromagnetic clutch. For details, please refer to the parameter table of electromagnetic brakes and clutches of Toke Company, or call for consultation. The high speed is determined by the high speed of the friction surface. If the speed exceeds this speed, the rated torque will not be generated, abnormal wear or overheating will occur.
Fourth, temperature
The electromagnetic brake and the electromagnetic clutch are B-class insulation, and the normal temperature rise is 40°C. The working temperature during thermal equilibrium is not allowed to exceed 100°C, otherwise the coil and friction parts are likely to be damaged.
V. Ventilation
Since electromagnetic brakes and electromagnetic clutches generate frictional heat to the outside, they must be installed in a ventilated place. When used in places with poor ventilation and heat dissipation, please pay attention to item 2 and use forced air cooling when necessary.
