a three$-$phase, y$-$connected, $460-$v$($line$-$line$),37-$kW$,60-$ Hz$,$ four pole induction motor has the following equivalent$-$circuit parameters in ohms$-$per$-$phase referred to the stator:

R$1=0\mathrm{.}070$ R$2=0\mathrm{.}152$ X$1=0\mathrm{.}743$ X$2=0\mathrm{.}764$ Xm$=40\mathrm{.}1$

the total friction and windage losses may be assumed constant at $390$ W and the core loss may be assumed to be equal to $325$ W$.$
