Product Description
Automatic web tension controller for magnetic powder clutch/brake
Magnetic powder brake can transmit torque based on electromagnetic theory and the use of magnetic powder.It has the characteristics which magnetizing current and transmit torque has a linear relationship,It has advantages of fast response,simple structure,no pollution,no noise,no shock and vibration,energy-saving and so on.It is a versatile,superior performance of automatic control components.Magnetic brake an also be used to buffer starting,overload protection,speed control and so on.
2.Features of magnetic powder brake
1)The transmission torque has a linear relationship with the magnetizing current. The size of the torque can get controlled within large range. Under normal circumstance, the magnetizing current has a linear relationship with transitive torque within range of 5%-100% rated torque.
2)The friction part will generate heat inevitably or even destroyed when it keep continuous sliding. But this device has a complete cooling set, it will not generate a lot of heat after long time running and it has a long service life.

The magnetic power clutch is composed of active rotor (input shaft), driven rotor (out shaft) and Yoke with excitation coil. The
three parts are assembled relative concentric and form a system which can rotate relatively. The annular gap between active rotor
and driven rotor is full of alloy powder which has high magnetic conductivity.
The magnetic power will be in the state of loose when the current do not pass the excitation coil. The magnetic power will be
thrown on the inner wall of active rotor. In this case, there will not exist the interaction force between the active and driven rotor. So the magnetic powder clutch is in the state of separation, no torque transmission exits.
The magnetic power in the working chamber will ink state under the action of the magnetic flux generated form the Yoke when the current pass the excitation coil. The magnetic powder clutch can transfer torque relying on the shear force generated from magnetic chain and the friction generated from the magnetic power and working face. In this case, the magnetic power clutch is in
the state of combination.
When the current is cut off, the magnetic flux will disappear with the disappearance of the magnetizing current, the magnetic
powder will be in the state of loose under the action of gravity again, and will be thrown on the inner wall of active rotor under the action of the centrifugal force. In is case, the magnetic powder clutch will be in the state of separation again.
The magnetic powder clutch and brake have the same principle, the magnetic powder brake will form as long as the driven rotor of
the magnetic powder clutch is fixed.

Advantages
Continuous Slip
Magnetic force, not rubbing, creates braking torque, so it can slip continuously without wear or loss of holding torque.
Uniform Reversing
The torque output is independent of slip speed, so that the torque setting remains constant as the it goes from maximum rpm forward to maximum rpm in reverse. Unlike friction brakes, our Magnetic powder brake never chatters or vibrates when reversing.
Uniform Intermittent Motion
Materials subjected to intermittent motions through reciprocating drives, indexing, ratchet or cam action, won't stretch or break.
Magnetic powder brake constant torque and holding force eliminate the uneven "stick-slip" phenomenon inherent in friction brakes.
Tension Control
our Magnetic powder brake makes unwind and payoff tension control simple and straightforward because torque output is directly proportional to current input. Open loop tension systems like roll diameter followers, or closed loop tension systems can utilize
Magnetic powder brake with either digital or analog electronic control techniques.
Long Life
Magnetic attraction and rugged construction make the it durable. With no rubbing parts subject to wear, our magnetic powder brake has a virtually unlimited life expectancy.
Temperature Stability
Our magnetic powder brake eliminates brake fade. Operating at a fixed current, it shows no significant torque variation even over temperature extremes.
Precise Loading
Input current determines torque characteristics. Ramp, taper, trigonometric, exponential and cyclic load functions are simple to obtain.
Clean
Our magnetic powder brake will not contaminate its surroundings with wear products, making it perfect for processing items like surgical dressings, photographic film, or food stuffs.
Smooth
Our magnetic powder brake doesn't subject your material or machinery to jerks, chatter or shake. It allows delicate process adjustment with infinite control.
Quiet
Our magnetic powder brake is very quiet. With no sliding or slapping parts, it is a valuable tool in the machine designer's portfolio.
