Answer Posted / dinesh verma
in indction motor, motor windings also plays a very
important role. these are also placed 120 degree apart. so
when you apply 3 phase supply, it forms a magnetic pole in
the stator. as the 3 phase supply is sinusoidal, the formed
magnetic pole starts rotation in one direction.

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
