Patent ID: 7946398

Claim:
Method for adjusting a braking torque of a permanently excited magnetic hysteresis brake by means of a mechanically acting actuator, characterised by providing only a single actuator ( 18 , 40 ) for adjustment of the braking torque and a cover ( 20 , 41 ) associated with the actuator, and by the steps of making both operational adjustment of the braking torque to a desired valued for the operation of the magnetic hysteresis brake ( 1 , 26 ) and fine calibrational adjustment of the braking torque when calibrating the magnetic hysteresis brake ( 1 , 26 ) via the single actuator ( 18 , 40 ), wherein the single actuator ( 18 , 40 ) entrains the cover ( 20 , 41 ) when the actuator ( 18 , 40 ) is rotated for fine calibrational adjustment of the braking torque and the actuator ( 18 , 40 ) rotates relative to the cover ( 20 , 41 ) for operational adjustment of the braking torque.
