Answer / neha

when an amount greater than the rated voltage and
current passing through the motor leading to increase
losses in the motor due to which it burns.

Answer / b soni

When the motor get mor Load Then its Capecty And If Ther is
a Single Phase In the three Phase Motor

Answer / manoj

When mototr takes more current then its rated capcity then
the insulation gets weeken of the winding & its results in
to flashover between two winding or winding to ground & it
gets burnt

Answer / kj

A motor will burn out because of the failure of the
insulation.
This can be because of heat from overload, high or low
voltage or not enough cooling. The insulation can also fail
because of moisture, age, dirt or salty environment.

Answer / tharan

over load, terminal losse connection,noise, flexibility amps variation that is y winding weak r gets burn..

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 frequency at maximum torque point is A 3.33% B 4.44% C 5.55% D 6.66%
