+// 3 phase induction motor

+Nss = 54;// Number of stator slots

+Nrs = 72;// Number of rotor slots

+// Calculation of the number of stator and rotor turns and rotor voltage between slip rings at standstill

+Ts = Nss*8/6;// Stator turns per phase.  Since 8 conductors per slot

+Tr = Nrs*4/6;// Rotor turns per phase.  Since 4 conductors per slot

+Es = 400/3^(1/2);// Stator voltage per phase

+//in book answers are 72, 48 and 266.7 Volts respectively.  The answers vary due to round off error
