phi_m = 0.05 // flux per pole in Wb
N = 600 // speed of machine in rpm
// caclulations
T_p = S/P // pole pitch interms of slots

k_p = 1 // pitch factor
Z = (180/3)*slots_1 // number of conductor per phase
T = Z/2 // number of turns per phase
f = P*N/120 // frequency in Hz
E = 4.44*k_p*k_d*f*phi_m*T // induced voltage in V
