can three phase induction motor rotate with only 2 phases
connected
Answer Posted / ram
Yes possible. Using capacitors you can run three phase
induction motors with high current rating. Normal current
rating is 1.5 amphere per HP for each phase;but for two
phase it will go up to 2.0 to 2.5 amphere for each phase.
Method: You can use running capacitors with 440 rating.For 1
Hp you need 12- 15 mfd capacitor/for 5 HP you need 60-70
mfd.You can make new phase via this capacitor from any one
of the remaining phases, if motor runs in reverse connect
capacitor in the other phase. For starting you may have to
add additional 100 mfd in parallel with the capacitor
previously described via make break switch of suitable
current rating for a moment.
