Why increase in current leads to increase in conductor temperature?
An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull out torque will occur. The rotor resistance per phase is 0.3 ohm and motor stalls at 650 rpm. The rotor reactance at stand still is A 2 ohm B 1.25 ohm C 3.15 ohm D 2.25 ohm
In constant power region of 3-phase IM torque-speed characteristics, if frequency increases flux A does not alter B decreases C increases D none of above
