What happens to an electric motor if it has poor or no
ventilation. Will it burn out? If it will, how long it
will run before it burn out?

Answer Posted / ullas k prabhu

Some times the motor may continue to rotate with lots of
heat dissipation or the motor windings might be suddenly
burnt which mainly depends on the class of insulators
used.... It also depends on the heating and cooling time
constants...

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
