Hollow Shaft Inner Shell Magnetic Powder Clutch

PRE-A2 magnetic powder clutch has the characteristics of easy wide-range control, continuous sliding, stable torque, quiet operation, good heat dissipation and long service life. The PRE-A2 type naturally cooled micro powder clutch has a small excitation current, but it can output a large torque, which makes it easy to form an automatic control system.

PRE-A2 Hollow Shaft Inner Shell Rotating Magnetic Powder Clutch

Introduction:

PRE-A2 hollow shaft inner rotating magnetic powder clutch, stop support, rated voltage DC24V.

PRE-A2 Model: 6N.m, 12N.m, 25N.m, 50N.m, 100N.m, 200 N.m.

PRE-A2 magnetic powder clutch has the characteristics of easy wide-range control, continuous sliding, stable torque, quiet operation, good heat dissipation and long service life. The PRE-A2 type naturally cooled micro powder clutch has a small excitation current, but it can output a large torque, which makes it easy to form an automatic control system. In addition, when the excitation current changes, the corresponding magnetic field strength also responds synchronously, and thus has a superior response speed.

When the excitation current remains unchanged, the output torque is not affected by the differential speed (slip speed) between the transmission member and the driven member, that is, there is no difference between the static torque and the dynamic torque. Therefore, the PRE-A2 type naturally cooled micro magnetic clutch can output a constant torque very stably. If this feature is applied to tension control, the customer only needs to adjust the magnitude of the excitation current to achieve the purpose of controlling the tension of the coil in a simple, effective and accurate manner.

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 mode(natural cooling/forced air cooling/water cooling) should depend on the maximum slip power when it works and the cooling air should pass the water and oil filter. The temperature detector and the alarm should be installed to prevent high temperature which can affect the service life of the magnetic powder.(the highest temperature is 80 degree).

Concerning the service life

The life of the magnetic powder clutch and brake rely on the life of the magnetic powder. Generally speaking, its service life is 4500-7500hours 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
