Magnetic powder brake & clutch features:


1) Excitation current and transmitting torque is almost in proportion, also transmitting torque is controlled with wide ranges.
2) Regardless of slipped rmp, torque is excellently transmitted.
3) Torque by residual flux is very little and stopping stability is excellent.
4) It can operate with slipping state, for large capacity cooling with heat.
5) Take short repair time as it is dry-type, so can use it for long time without any adjustment.
6) It is friction clutch of based on the powder.

Electromagnetic clutch & brake kit Key Features (SMP)






 






1. With non-asbestos lining, makes the product not easy to wear out and lasts long.






2. Start, stop, high-frequency operation, positioning.






3. Super thin designed doesn't occupy much space, input side at the fly wheel and output sleeve at the transmission shaft easy for installation.

Powder Clutch and Brake Application






 






Due to the feature of the magnetic powder

clutch and brake, they have been widely used in paper making, printing, plastic

items, rubber industry, textile industry, printing and dyeing, wire and cable,

metallurgy industry and tension control of winding and unwinding in roll

material processing industry. A complete set of schematic of tension control

system is as follows.





















Note:






The magnetic powder clutch can be also used

in buffering start, overload protection, speed adjustment; the magnetic brake

can also be used in test loading and braking of transmission machinery.






 






Design reference






First, let us learn the meaning of the

following words:






1. Slip rotational speed: the speed

difference between input shaft and output shaft is magnetic powder clutch, the

rotational speed of output shaft for magnetic powder brake.






2. Slip powder: the powder generated from

the slip rotational speed when the magnetic powder clutch or brake transfer

torque.






The selection of the magnetic powder clutch

or brake rely on the maximum required torque and rotational speed. Because the

temperature of all parts will rise when the slip power is converted into heat,

it is guaranteed that the actual slip power is less than the rated value.

Iron Powders for Powder Brakes and Powder Clutches





Powder brakes and powder clutches are electromagnetic devices that provide precise, quick-response tension control for light tension applications. Powder brakes also known as magnetic particle brakes (or magnetic brakes) are quiet alternatives to friction brakes, and are ideal for clean environment situations.



How magnetic brakes work?



Magnetic particle brakes are comprised of an electromagnet and a disk inside a powder chamber. The disk can spin using a shaft that extends to the outside of the chamber. Without any magnetic field the powder acts like a fluid and the disk can spin freely. A magnetic field produced by the electromagnet will harden the powder causing friction so that the disk can no longer spin freely. The tension is controlled by the strength of the electromagnet.



Iron powders for magnetic particle brakes and magnetic particle clutches?



Selecting iron powder for magnetic particle brakes and clutches is a delicate task. Some of the important factors affects the operation of a magnetic particle system are the particle shapes, hardness and magnetic properties. For example, very hard particles with sharp edges can grind and damage the internal structure of a powder brake or powder clutch system. Using iron powder with spherical particles prevents such problems.
