No, 1 phase power supply can excite one winding only.But 3
Phase motor having 3 windings for that it Requires 3 Phase
supply...

Answer / wareagle

Use a vairable speed drive. It will take the single phase
and convert it to 3 phase. Make sure the motor is rated for
drives.

Answer / navdeep

By using Capacitors we can convert 1-phase to 3-phase

Answer / gourav buldev

to generate rotating magnetic field RMF we use capacitor as a psuedo magnetic field in our home fans so we can apply this in this condition also..

Answer / snk

fix a capacitor in between two winding that will split the
phase angle difference of angle will produce rotating field
and motor will start moving.

Answer / sumit patel

not at all.
bcoz if we give single phase supply to the motor.,it won't create rotating magnetic flux. rotataing magnetic flux is must for the motor to run.

Three set (each phase contain 2 cable of 400 mmsq CU XLPE AWA) of single core cables are connected to 11 KV motor of 14 MW & the switch gear supplay is taken from 11kv feeder & this supplay taken from 275 KV substation. Problem is one pair cable(L3- 2 cable ) getting very hot & gland melted and damaged in switch gear side. the other two cable haven't any more hot(ambient temp only & L3 haveing 95- 100 Degree C. The same problem happened in 275 KV substation switch gear side also where the supply taken for 11 kv switch gear. But here L2 phese cable had problem. Why it is happening like this?. The cable having temperature different at different location from gland side inthe case of 11KV feeder of 275 kv substation. why ?
