[Also in Division H2] Rotational oscillations in the rotor 3, 4 of a stepper motor are damped by a flywheel 13 carried on a ball or roller bearing 14, 15, 16 having considerable rotational stiffeners. This friction may be produced by the use of a viscous liquid in which the balls roll, but as shown, it is produced by tightening the race on a core 18 by means of nut 21.</p> |
