A no load test conducted on a 30 Hp, 835 rpm , 440V 3-phase 60 hz squirrel cage induction motor yielded the following results. No load voltage line to line = 440V No load current = 14A No load power = 1470 W Resistance measured between two terminals = 0.5Ω The locked rotor test conducted at reduced voltage gave the following results. Locked rotor voltage line to line = 163V Locked rotor power = 7200W Locked rotor current = 60A Determine the equivalent circuit of the motor.

A no load test conducted on a 30 Hp, 835 rpm , 440V 3-phase 60 hz squirrel cage induction motor yielded the following results.
No load voltage line to line = 440V
No load current = 14A
No load power = 1470 W
Resistance measured between two terminals = 0.5Ω
The locked rotor test conducted at reduced voltage gave the following results.
Locked rotor voltage line to line = 163V
Locked rotor power = 7200W
Locked rotor current = 60A
Determine the equivalent circuit of the motor.
