- A 460 V 25 Hp 60 Hz Four Pole Y Connected Induction Motor Has The Following Impedances In Ohms Per Phase Refer 1 (118.19 KiB) Viewed 45 times
= = = A 460-V, 25-hp, 60-Hz, four pole, Y-connected induction motor has the following impedances in ohms per phase referred to the stator circuit: R1 = 0.64112 R2 = 0.33212 X1 = 1.10612 X2 = 0.46412 XM = 26.312 The total rotational losses are 1100 W and are assumed to be constant. The core loss is lumped in with the rotational losses. For a rotor slip of 2.2 % at the rated voltage and rated frequency, find the motor's a) Speed d) Pcony and Pout b) Stator current e) Tind and Tload c) Power factor f) Efficiency
