- A 30 Kw 460 V 1180 Rpm 3 Phase 60 Hz Y Connected Induction Motor Has A Full Load Efficiency Of 93 6 And A Power Fa 1 (14.29 KiB) Viewed 23 times
A 30 kW, 460 V, 1180 rpm, 3-phase, 60 Hz, Y-connected induction motor has a full-load efficiency of 93.6% and a power factor of 0.83 lagging. The resistance of the stator winding per phase is 0.141/phase. Determine: (a) The full-load active power drawn by the motor (20 marks). (b) The full-load line current (20 marks). (c) The full-load rotor winding losses (40 marks). (d) The rotational losses (20 marks).
