How To Customize The Right Magnetic Particle Clutch?

Definition of magnetic particle clutch:
Magnetic particle clutch is also known as electromagnetic powder clutch, magnetic powder clutch.
Is based on the electromagnetic principle and the use of magnetic powder to transfer torque, with the excitation current and the transfer of torque is basically a linear relationship, in the case of the same slip is not relevant to be able to transfer a certain amount of torque, with a fast response speed, simple structure, no pollution, no noise, no impact vibration energy saving advantages, is a multi-purpose, superior performance of the automatic control components. According to the classification of shaft type, there are: double shaft magnetic particle clutch, hollow shaft magnetic particle clutch, hollow shaft magnetic particle clutch, according to the classification of cooling method, there are: self-cooled, air-cooled and water-cooled and so on.

The principle of magnetic particle clutch:
1. The excitation current is linearly related to the torque.
Powder clutches and powder brakes are based on the electromagnetic principle and utilize magnetic powder to convey torque, and the torque conveyed is basically linearly related to the excitation current. Therefore, the amount of torque can be easily controlled by changing the amount of excitation current. Under normal circumstances, in the range of 5% to 100% of the rated torque, the excitation current is linearly proportional to the torque it conveys.
2. Stable slip torque
When the excitation current is kept constant, the torque conveyed is not affected by the difference in speed between the drive and the follower, i.e., there is no difference between the static torque and the dynamic torque. Therefore, a constant torque can be transmitted stably. If this characteristic is applied to tension control, the user only needs to adjust the magnitude of the excitation current to accurately control and convey the required torque, thus easily and effectively achieving the purpose of controlling the tension of the rolled material.
3.Scope of application of magnetic particle clutches
Due to the above characteristics of magnetic particle clutch and brake, it is now widely used in paper making, printing, plastic, rubber, textile, printing and dyeing, wire and cable, metallurgy, and other related winding and processing industries in the unwinding and winding tension control. In addition, magnetic particle clutches can also be used for buffer starting, overload protection, speed regulation and so on. Magnetic particle brakes are also often used for dynamometric loading and braking of transmission machinery.
4. The selection of magnetic particle clutch is generally selected on the basis of the maximum torque to be conveyed, and at the same time, attention is paid to ensure that the actual slip power is less than the permissible slip power of the magnetic particle clutch.

Characteristics of magnetic particle clutches:
1、Magnetic particle clutch and brake is a kind of automatic control element with superior performance.

6, aluminum alloy construction, with excellent heat dissipation performance, good demagnetization, fast response speed.
7, smooth operation, no vibration, no impact, no noise in the starting, running, braking state.
8、 The torque is proportional to the excitation current within the specified torque range, and it can be used as a linear regulating element.
9, the output torque is constant, because the size of the torque depends only on the size of the excitation current, and has nothing to do with the slip speed.
10、Frequent closing, fast response, high frequency, up to 40-60 times per minute, can be widely used in fast working condition and high frequency occasions.
11, high power amplification, can be a very small excitation current to control a large transfer power, easy to realize automatic control.
12, smooth running, in the start, running, braking state, no vibration, no impact, no noise.
13, overload protection, in the case of torque overload, automatic slip operation to play the role of overload protection.

The use of magnetic particle clutches:
1、Cushioning for starting and stopping: Utilizing the cushioning effect of the sleek characteristics and constant torque characteristics of the linkage, i.e., stable acceleration and no shock peak torque.
2、Continuous sliding, tension control.
3、For torque limiter
4、For high speed response
5、For power absorption
6、For positioning stop
7、For analog load
8、It can be used for clutching and torque braking in the process of torque transmission.
9、It is suitable for constant tension control system, such as: printing machine, slitting machine, laminating machine, coating machine, papermaking machine, wire drawing machine and cable winding machine, as well as metal plate, strip, film and other processing equipment and textile machinery.
10, can replace the ordinary clutch, used for machine tools, fast clutch, CNC devices, computers, wide line printers and a variety of precision machinery.
11, as an overloader, can be applied to mining hoisting machinery, lifting machinery and cement, steel and other machinery and equipment, can make the prime mover no-load start, gradually loaded, improve the load capacity of the equipment.
12, stepless speed regulation, with sensors and control lines can be realized stepless speed regulation, especially for high speed fine-tuning speed and small and medium power speed control system.
13, overload protection, when the work system accidentally, torque overload, the clutch automatically slip, so as to protect mechanical equipment and raw power.
