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 is designed to run at nearly constant speed over its entire load range, i.e., from no load to full load. This is because the slip (difference between synchronous speed and rotor speed) remains very small and does not vary significantly with load. This characteristic is critical in industrial applications where a stable motor speed is necessary regardless of load fluctuations.
