About this document
Crawling and Cogging in Induction Motors by Chhaya Tiwari is a document available to read on EtoBox.
The document discusses two characteristics of squirrel cage induction motors: crawling and cogging. Crawling occurs when the motor runs at a very low speed, around 1/7 of its synchronous speed, due to harmonic torques produced by the stator winding. Cogging occurs when the rotor and stator slots align, preventing the motor from starting up. The document then discusses various methods for controlling the speed of induction motors, including adjusting the supply voltage and frequency via V/f control, changing
