Magnetic powder is a special magnetic powder for clutch brakes. It has high magnetic induction, high magnetic permeability, low remanence, low coercivity, high Curie point and large transmission torque. And has good heat resistance, wear resistance, thermal conductivity and chemical stability. In the military, civil and other fields, it is mainly applied to various magnetic torque clutches, magnetic powder brakes and tension controllers with high torque and high slip.
After using the general magnetic powder for a period of time, the torque will fall below the required tension, and new magnetic powder must be replaced at this time. Therefore, the selection of the magnetic powder material is very important. The use of high-quality magnetic powder can improve work efficiency, prolong the use time, reduce the cost, and prolong the use time of the magnetic powder brake (clutch).
If your machine speed drops, the torque ripples, and the rotor is suddenly stuck when operating at the rated excitation current, consider replacing the new magnetic powder.
The magnetic powder brake mainly relies on magnetic powder to transmit torque, and its service life is directly related to the use of magnetic powder. Magnetic powder is a consumable, so its service life directly affects the operation and performance of the entire magnetic powder brake, including the subsequent production work. The service life of the magnetic powder is directly affected by the operation time, load, temperature (not exceeding 90 degrees Celsius) and frequency of the magnetic powder brake. Since the inside of the magnetic powder brake is relatively tight, once it is in operation, its internal and surface will be generated. temperature. The longer the operation time, the higher the temperature inside and on the surface of the magnetic powder brake. In addition, if the weight of the load is larger, the required torque is larger, and the higher the operation frequency, the faster the magnetic powder consumption speed.
Note that the magnetic powder brakes generally rely on two aluminum back covers (self-cooling or air-cooled) or other heat sinks. Magnetic powder brakes are the most common type of self-cooling and water-cooling. The self-cooling type is the aluminum cover of the magnetic powder brake device for heat dissipation and ambient air flow, while the water-cooled type uses water to use the magnetic powder brake. The internal and surface temperatures drop, providing the use and performance of the magnetic powder. The main purpose of these two heat dissipation methods is to reduce the temperature inside and on the surface of the magnetic powder brake, and to improve the service life and performance of the magnetic powder brake and the magnetic powder.
In addition, the magnetic powder life of the magnetic powder brake is directly related to the quality of the magnetic powder itself. The better the quality, the longer the magnetic powder has a longer service life, the more the performance can be exerted, and the worse the quality of the magnetic powder, the service life and performance of the magnetic powder. It will drop a lot. Under normal circumstances, the use of magnetic powder can reach 6000 to 8000 hours, provided that the load is not overloaded, the cooling is in place, the torque and the slip power are within the rated range.
