Foot Mounted Magnetic Powder Clutch 1000NM Voltage 36V 3.5 A For
Slitting Machine
General introduction:
The magnetic powder clutch is composed of active rotor (input
shaft),driven rotor(output 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 magnetic alloy powder which has high
magnetic conductivity.
The magnetic powder will be in the state of loose situation when
the current do not pass the excitation coil, the magnetic powder
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 powder in the working chamber will link in a link
state under the action of the magnetic flux generated from 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
powder and working face. In this situation, the magnetic powder
clutch is in the combination state.
When the current is cut off, the magnetic flux will disappear along
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 this 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 driven rotor of the
magnetic powder clutch is fixed.

Application:
Magnetic powder brake is widely used in packaging machines,
printing presses, slitting machine, paper machinery, textile
machines and other transmission equipment.
1. Notes
Don’t overload, meanwhile cool to appropriate temperature
The value of the torque/rotational speed/slip power should be less
than the rated value, The cooling model(natural cooling. forced air
cooling/water cooling)should depend on the maximum slip power when
it works and the cooling air should filter the water and oil. The
temperature detector and the alarm device should be installed to
prevent high temperature which can affect the service life of the
magnetic powder.(the highest temperature is 80 degree)
The life of the magnetic powder clutch and brake rely on the life
of the magnetic powder. Generally speaking, its service life is
4500-7500 hours in the state of non overloaded, but its service
life can extend several times in some cases, such as: the working
torque of the magnetic powder clutch/brake, relative slip
rotational speed and slip power can be reduced to 50%-70% of the
rated value. This is to say, the margin can be enlarged as soon as
possible when designing.
Concerning the torque
After the magnetic powder clutch and brake working, the magnetic
powder will be in grinding at the beginning which lead to the
torque decreasing slightly, but the gap can be compensated through
adjustment the current.
2. Remarks:
(1): The formal installation method (high-speed rotating side as
the input side) to use magnetic powder clutch.
(2): Please note that the moisture. Magnetic particle moisture, the
performance will become unstable, so be especially careful not to
let the oil or moisture intrusion internal.
(3): Please note that the surface temperature.
