General introduction
The magnetic powder clutch is composed of the active rotor (input shaft), driven rotor(output shaft), and yoke with an excitation coil. The three parts are assembled relative concentric and form a system that can rotate relatively. The annular gap between the active rotor and the driven rotor is full of magnetic alloy powder which has high magnetic conductivity.
Technical parameter
Features
The magnetizing current has a linear relationship with torque
The transmission torque has a linear relationship with the magnetizing current. The size of the torque can get controlled within a larger range. Under normal circumstances, the magnetizing current
Has a linear relationship with transitive torque within the range of 5%-100% rated torque.
Stable slip torque
The slip rotational speed between the driven rotor and the active rotor does not affect the transitive torque when the magnetizing current remains unchanged, as shown in chart 4. That is to say, the static friction torque and the dynamic friction torque have no difference. Therefore, the torque can remain constant stably. The features are applied to tension control, users can control the tension of the roll material effectively as long as adjustment the magnetizing current accurately.
Prevention of heat phenomenon from slip
The friction part will generate heat inevitably or even be destroyed when it keeps continuously sliding.
But this device has a complete cooling set, it will not generate a lot of heat after a long time of running and it has a long service life.
Notes
Don’t overload, meanwhile cool to the appropriate temperature.
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 work, the magnetic powder will be in grinding at the beginning which leads to the torque decreasing slightly, but the gap can be compensated by adjusting the current.
