REQUIREMENTS

Single phase stator rms voltage = V_s1^rms = V (e.g. 220V)
Speed = n_r = rpm (e.g. 1400rpm)

You must assign just two of the following three Total (stator and rotor) input power = P_i = W
Shaft output power = P_o = W (e.g. 4000W)
Efficiency = (e.g. 0.80)
(For a generator example, any two of P_i = -1000W, P_o = -1170W, Efficiency = 1.17)

Number of pole pair n_pp = (e.g. 2)
Mechanical to total loss rate = k_ml = P_f / P_loss = (e.g. 0.25)
Saliency ratio = k_dq = L_sd / L_sq = (e.g. 1.5) (1 for cylindrical rotor)
Stator input power factor cosφ₁ = (e.g. 0.8)
Mechanical time constant = τ_mec = J_i / B_f = s (e.g. 0.25s)
Leakage coefficient between the stator and rotor = σ_f = 1 - M² / (L_sdL_f) = (e.g. 0.02)

You must assign just two of the following three Excitation voltage = v_f = V (e.g. 24V)
Excitation current = i_f = A (e.g. 8.333A)
Excitation to total loss rate = k_rl = P_CuRot / P_loss = (e.g. 0.2)
