"For a $200$ V $,$ single phase, $50Hz,1440rpm$ induction motor, following are the test data:

Blocked rotor test : $48$V$,12$A$,520$W

No Load Test: $220$V$,10\mathrm{.}4$A$,380$W

Determine the equivalent circuit parameters."

For a split phase single phase induction motor, derive the condition for maximum starting torque.
