A 3000 V, 24 pole, 50 Hz, 3-phase, star connected induction motor has ...
Concept:
The ratio of maximum torque to full load torque is
Where sm is the slip at maximum torque.
sfl is the slip at full load torque.
Slip at maximum torque,
R2 is the rotor resistance
X2 is the rotor reactance
Calculation:
Given that, Number of poles (P) = 24
Frequency (f) = 50 Hz
Rotor resistance (R2) = 0.016 Ω
Rotor reactance (X2) = 0.265 Ω
Slip at maximum torque,
Speed corresponding to full load torque (Nr) = 247 rpm
