m-matically in Fig. 3. The equation may be set up thus: T _d2o de L = J 5 + K —- + a 6 d t2 d t where J * M^> = Moment of inertiaL = disturbing moment K = moment of retarding force per unit angular velocity,a * twisting moment per unit angular displacement - 8 - This is a forced oscillation. Wow… … Each of the three terms represents a moment in-side the armature, and their sum must equal the moment ofdisturbing force, zero in this case. J is the moment of inertia of the rotating part, and - 9 - a2 q J represents the moment required for its acceleration. d t a is the twisting moment per unit…
