摘要:
A permanently excited magnetic hysteresis brake (1) comprises a support roller (7) rotatable about a fixed axle (9), a magnetic element (3), a hysteresis element (2) and an adjusting device for adjusting the position of the magnetic element (3) and hysteresis element (2) relative to one another and for adjusting the braking torque acting via the support roller (7) on the yarn (5). The magnetic hysteresis brake (1) has only one single mechanically acting actuator (18) for adjusting the braking torque. Both the adjustment of the braking torque to the desired value for the operation of the brake (1) and the adjustment of the braking torque when calibrating the brake (1) are carried out by actuation of this one actuator (18). The structure and handling of the magnetic hysteresis brake (1) can be simplified thereby. The magnetic hysteresis brake (1) can be used to maintain a uniform thread tension on textile machines.
