Definition, Meaning & Synonyms

cogging

noun

/ˈkɒɡɪŋ/

Definition

Cogging is a term used to describe a type of operation found in electric motors, particularly in relation to the interaction between the rotor and stator magnetic fields that can lead to jerky motion.

Examples

The cogging of the motor made it difficult to start smoothly.
Engineers are working to reduce cogging in high-performance electric motors.
Cogging can result in uneven torque in applications requiring precise control.

Meaning

The word ‘cogging’ refers to the phenomenon where a motor experiences a reluctance in movement when starting due to the permanent magnets’ attraction to the teeth of the stator.
