my teacher said when a heavy load motor run low voltage he was burn because router rotation and field rotation difference is directly pro to voltage its mine voltage is up. when voltage is up. according to ohm low current is high and motor winding is burn but i'm not conform please give me a long answer with example
With an AC motor running on a reduced voltage, slip is increased. That is the difference between the speed of the rotor and the rotating magnetic field in the stator, increases. When this happens more voltage is induced in the rotor bars, so more current flows in them. By transformer action, the current in the stator windings also increases and may lead to overheating and burn out.
