Answer Posted / mahesh meshram
If HT motor fed on LT supply, motor will run slowly and speed will increase with time. Initially motor will draw app. 1/3rd of the rated current and it will also reduce by 2-5 amp and will get steady.Motor such type of performance is expected only if it's bearing, rotor and other factors are good.

For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
