Features And Functions Of Magnetic Powder Brake

1. High-precision torque control The control range of the torque is very wide, and the control accuracy is high. It conveys the torque and the exciting current into the correct ratio, which can achieve high-precision control.
2. Superior durability and long life The super alloy magnetic powder with heat resistance, wear resistance, oxidation resistance and corrosion resistance is used for long life.
3. Constant torque characteristics with excellent stability The magnetic characteristics of magnetic powder are good, and the binding force between the particles is stable, the sliding torque is very stable, and it has no relationship with the relative number of revolutions. It can maintain a constant torque for a long time.
4. Continuous sliding operation. Excellent heat dissipation effect and uniform thermal deformation cooling structure, coupled with the high heat resistance of magnetic powder, allowing large connection and braking power and sliding power, smooth sliding operation without causing vibration.
5. Smooth connection, no impact The impact during connection is extremely small, and it can start and stop smoothly without impact. And the resistance torque is extremely small, which will not cause useless heat generation.
6. Magnetic powder brake is suitable for high-frequency operation. The response is quick and fast and the special heat dissipation structure is suitable for high-frequency operation.
7. Lightweight, maintenance-free, long life Simple and lightweight type, using high temperature resistant coils and special grease bearings, and applying abrasion-resistant special treatment to armatures that are prone to wear and tear, extending the service life.

Magnetic powder is a necessary material for magnetic powder brakes. It mainly uses 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 life of magnetic powder is directly affected by the operating time, load, temperature (not more than 90 degrees Celsius), and frequency of the magnetic powder brake. Because the interior of the magnetic powder brake is relatively tight, once it is running, its interior and surface will produce temperature. The longer the running time, the higher the temperature of the inside and the surface of the magnetic powder brake. In addition, if the weight of the load is more, the larger the required torque, the higher the operating frequency and the faster the magnetic powder is consumed.
Note that magnetic powder brakes generally rely on two aluminum back covers (self-cooled or air-cooled), or other heat sinks. The magnetic powder brake has the most common self-cooling and water-cooling types. The self-cooling type uses the aluminum cover of the magnetic powder brake itself to dissipate heat and the surrounding air current environment, while the water-cooled type relies on water to use the magnetic powder brake. Internal and surface temperatures drop, providing magnetic powder use and performance. The main purpose of these two heat dissipation methods is to reduce the temperature of the inside and the surface of the magnetic powder brake, and to improve the service life and performance of the magnetic powder brake and the magnetic powder, as well as the working efficiency.
In addition, the life of the magnetic powder of the magnetic powder brake has a direct relationship with the quality of the magnetic powder itself. The better the quality, the longer the life of the magnetic powder, and the better the performance, the worse the quality of the magnetic powder. Will drop a lot. Under normal circumstances, the use of magnetic powder can reach 6000 ~ 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.
