The Different between magnetic powder brake and hysteresis brake

The Different between magnetic powder brake and hysteresis brake
1.The principle is different: magnetic powder brake is controlled by electromagnetic force magnetic powder viscosity to achieve braking, and hysteresis brake is the use of hysteresis phenomenon to produce braking torque.
2.The application is different: the magnetic powder brake is suitable for light load, high speed and continuous braking, and the hysteresis brake is suitable for large load, low speed and intermittent braking.
3.The characteristics are different: the magnetic powder brake has a fast response speed, but it needs a cooling system to dissipate heat, and the magnetic powder needs to be replaced regularly; Hysteresis brake has large braking torque, but large volume, heavy weight and slow response speed.
