- Crawling typically causes an induction motor to operate at a fraction (e.g., 1/3) of synchronous speed.
- Crawling is a phenomenon in squirrel-cage induction motors caused by harmonics in the supply voltage or due to the motor's design.
- This results in the motor getting "stuck" at around (1/3)th of the synchronous speed instead of accelerating to near synchronous speed.
- It is commonly observed in motors with poor design or under heavy load during startup.
- Crawling is often accompanied by high starting currents and can produce noticeable noise, further impacting the motor's operation and potentially damaging the surrounding environment.
