In 3 phase induction motor 1hp current rating is 1.5 amps
constant ? is correct or not ?
Answer Posted / pradyumna chandra panda
It is not justificable that current rating of 3ph motor is culculate to 1.5 amp per hp. Reactive power is more in higher size hp motor ie. slight less current per hp. And reactive power is less in lower size hp motor ie. more current per hp. Normaly 3ph 1hp motor take 1.8 amp per phase (phase current) Simiarily current rating of 3ph 5hp is 7.5 amp, 10hp is slight less then 15 amp and 100 hp motor is approximately 140 amp.
