In 3 phase induction motor 1hp current rating is 1.5 amps constant ? is correct or not ?..

Answer / jatin

the current rating of an induction motor depends upon the load . so the value of current will change as per the load and not remain constant at 1.5 amps

Answer / narendra korrapati

motor amps is depends upon load.if load increase on motor
the full load amps will be change.practicaly i saw a 3-
phase 1 hp motor takes 3.5 amps

In 3 phase induction motor 1hp current rating is 1.5 amps constant ? is correct or not ?..

Answer / m bilal akram

a motor have manufacture at limited load if we put on extra
load may b motor winding brake at full load motor take
constant current if voltage and power factor also constant
however its Change current also Change.if load change
current also change.

Answer / 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.
