Magnetic Powder Brake Is A Multi-purpose, Superior Performance Automatic Control Element

Magnetic powder brake is a multi-purpose, high-performance automatic control element, which is widely used in braking of various machines, power test loading, unwinding tension control, etc. The main working medium of magnetic powder brake is magnetic powder. This material itself has a certain magnetism. It uses magnetic powder brake to achieve high-speed operation.
Because of the above characteristics, magnetic powder brakes and brakes have been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy and other related coiling and processing industries for unwinding and rewinding tension control. In addition, the magnetic powder clutch can also be used for buffer starting, overload protection, speed regulation, etc. Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery.

Magnetic powder brake and magnetic powder clutch are an automatic control element with superior performance. It uses magnetic powder as the working medium and excitation current as the control means to achieve the purpose of controlling braking torque or transmitting torque. Its output torque has a good linear relationship with the exciting current, and has nothing to do with the speed or slip, and has the advantages of fast response speed, simple structure and so on.
For automatic tension control system. Magnetic powder brakes and magnetic powder clutches are matched with automatic tension controllers and tension detection sensors to form automatic closed-loop tension control systems. They are widely used in printing, packaging, papermaking and paper processing, textiles, fiberglass, rubber and leather for metal wires, cables Processing and other equipment.
For torque speed power test system. Magnetic powder brake and magnetic powder clutch are matched with torque speed sensor and torque speed power measuring instrument to form a complete set of torque speed power test system, which is widely used in the input, output torque, speed, power and efficiency of power machinery and transmission machinery. Dynamic and static detection
Magnetic powder clutch is also used for cushioning start, overload protection, speed regulation, etc.
Working principle of magnetic powder brake
Magnetic powder brake is based on electromagnetic principle and uses magnetic powder to transmit torque. It has the characteristics of a substantially linear relationship between the exciting current and the transmission torque. It can transmit a certain amount of torque without being related to slip, and has the advantages of fast response speed, simple structure, no pollution, no noise, no shock vibration and energy saving. It is a multi-purpose, high-performance automatic control element. Has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet presses and other related winding processing industry unwinding and rewinding tension control. Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery. Magnetic powder brakes and magnetic powder clutches are often paired.
Magnetic powder brake use:
1. For buffer start and stop: use the smooth characteristics and constant torque characteristics when connected to achieve buffer start and stop.
2.For continuous sliding and tension control
3.For torque limiter
4.For high-speed response
5.For power absorption
6. For positioning stop
7.For simulated load
Magnetic powder brake has the following characteristics:
1. Can control a wide range easily.
2, can achieve continuous sliding operation.
3. Stable torque can be obtained.
4. No tweet sound. The slipping phenomenon of the action surface occurs in the friction mode, but it does not appear here, and no connection sound is emitted, so the operation is quite quiet.
5. The heat capacity is very large. Due to the use of magnetic powder with excellent heat resistance and the ideal cooling method, it can be used safely even in the severe continuous sliding operation.
6, can achieve smooth continuous and driving state. Since the static friction coefficient and the dynamic friction coefficient are almost the same, vibration will not occur when fully connected, and it can respond to load acceleration and deceleration.
Precautions for using magnetic powder brake:
1. Please pay attention to moisture. If the magnetic powder gets wet, the performance will become unstable, so be careful not to let oil or moisture penetrate into the inside. In particular, when installing in a gearbox, oil will penetrate the shaft through the shaft, so it must be completely sealed with a film.
2. Please pay attention to the surface temperature. The maximum surface temperature caused by continuous operation is 90 degrees or less during operation. When this value is exceeded, durability will be greatly reduced. Be sure to use the above-mentioned limit temperature as the standard, and be sure to keep it within the allowable sliding working rate during use.
