What is the reason of polyphase induction motor tripping suddenly on high current during running at 70% laod? Motor IR , winding resistance & inductance balance. Motor no load current is balance and ok as per mgfr. data.
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
