3) A three phase Induction motor with the following parameters:
•
$R_1$ = 220m?,
•
$X_{11}$ = 430m?,
•
$R_2$ = 127m?,
•
$X_{12}$ = 430m?,
•
$X_m$ = 15?,
•
$P_{mech}$ = 300W,
•
$P_{core}$ = 200W,
•
$P_{misc}$ = 0,
•
#Poles = 4,
is connected in Y configuration to a 60Hz source with 120V per phase.
For a slip of 5%, determine:
a) The phase current, and copper losses at the armature.
b) The air-gap power, and the power converted to mechanical
c) The induced and load torque
d) The overall motor efficiency
e) The motor speed in RPM and rad/sec
