Question

Three-phase induction motor runs at constant speed from . (No load to full load/Medium load to high load)

Answer 1

A three-phase induction motor maintains a near-constant operational speed across its entire load spectrum, from zero load to maximum load. This constancy is attributable to the minimal and stable slip (the disparity between synchronous and rotor speeds) irrespective of load variations. This inherent stability is crucial for industrial environments demanding consistent motor speed despite fluctuating operational demands.
