How Is The Hollow Shaft Magnetic Powder Brake Used?

The use of hollow shaft magnetic powder brakes has the following points:
1. When the hollow shaft magnetic powder brake and the clutch are used for continuous sliding of winding and unwinding, the product and life may vary depending on the conditions of use (relative sliding speed, etc.). However, in general, the life of iron powder in reducing the rated torque in the constant current is about 4500 to 7500 hours. However, in some cases, it is not available for the rated torque, so it can be used continuously and the life can be extended. However, even if the sliding operation rate is the same, the sliding rotation speed, that is, the relative rotation speed is continuously high, the life tends to be reduced. Therefore, it is necessary to reduce the relative rotation speed at the time of setting.

2. In order to prolong the life of the iron powder, it is also a way to allow the sliding work rate to be sufficient when used. For example, if it is used at 50% of the allowable sliding operation rate, the life expectancy can be extended to double.

3. If the driven member is used as the input side, it will continue to idle for a long time, and the iron powder will be stirred, and the life will be greatly reduced. Please try to avoid this method. If it is unavoidable in any way, please set the current to weak excitation when using. When operating at low speed (16 RPM or less), stable torque characteristics are generated during continuous operation such as tension control. However, in the case of intermittent rotation with idling, after the voltage is applied, the start of the torque may be delayed, and this situation may not be avoided. Please use it as described below.

1. Even if the end of the roll is over, continue to give weak excitation (constant 7-150% current) so that the iron powder does not fall from the action surface;

2. Please increase the speed and the low rotation speed to 16RPM.

3. The magnetic powder brake should not be operated in a humid environment to avoid damage to the magnetic powder. After the magnetic powder brake is used, relevant maintenance and maintenance are required to ensure the service life. In addition, the magnetic powder brake installation environment, please choose a dry, ventilated environment, avoid moisture, dust. The hollow shaft magnetic powder brake needs to add a certain amount of magnetic powder. The magnetic powder brake uses magnetic powder to transmit torque, and the quality of the magnetic powder determines the quality of the magnetic powder brake.
