6Nm-200Nm Magnetic Powder Brake Features
1. The excitation current is linear with the torque. The transmitted torque is substantially linear with the excitation current. As long as the magnitude of the stimulation current is changed, the magnitude of the torque can be controlled over a wide range. In general, the stimulus current is substantially proportional to the transmitted torque in the range of 5%-100% of the rated torque.
2. Stable slip torque. When the stimulation current remains unchanged, the transmitted torque is not affected by the difference in rotational speed between the active and the driven, that is, there is no difference between the static friction torque and the dynamic friction torque, so that the torque can be stably achieved. This feature is applied to the tension control, and the user can accurately control the torque by adjusting the stimulation current, thereby effectively controlling the tension of the roll.
3. Prevent heat generation due to slip. Generally, the friction part is inevitably heated or even burned when continuously sliding. However, the ATO magnetic powder brake has a complete heat sink, which will not be too hot for a long time and has a long service life.

Hollow Shaft Magnetic Powder Brake Application
Tips: Notes for Use of Magnetic Powder Brake
1. Please pay attention to moisture. Magnetic particles can become unstable with moisture, so be careful not to let oil or water enter the interior. Especially when installed in the gearbox, the oil will penetrate into the interior through the shaft, so the film should be completely sealed.
2. Please pay attention to the surface temperature. The maximum surface temperature caused by continuous operation is below 90 degrees during operation, beyond which, the durability will be greatly reduced. Be sure to take the above limit temperature as the standard and use it within the allowable sliding rate.
