A 30 PM machine has electrical parameters: Rs = 0.2N, Ls = 200µH, and ApM = 20mWb, and has mechanical parameters: Bm = 0.01Nms, Jm = 0.5 kg m², and p = 16 poles. a. If the machine operates with ig = 50A, wm = 100rad/s, and TsH = 5Nm, what will be the angular acceleration of the machine, a, in [rad/s?]? Ignore any static friction, To = 0. b. If the machine operates at steady-state (all derivatives equal to zero) with parameters: wm = 200rad/s, TsH = 10NM, ia = 0A, iq = 50A, va = -16V, & vą = 42V, compute the efficiency of the machine, ŋ, considering copper and friction losses. %3D
