However, in this case, it is necessary to use an expensive magnet material in order to obtain a necessary holding torque. There is a problem. Further, the holding torque and the braking torque do not necessarily have to be the same, and in some cases, the braking torque may cause an output loss, so that it may be desirable to eliminate this. However, it is difficult to adjust these ratios with a simple hysteresis brake.
