Cogging Meaning: Definition, Examples, and Translations
⚙️
cogging
[ˈkɒgɪŋ ]
Definition
mechanical engineering
Cogging refers to a phenomenon in mechanical systems, particularly in electric motors and generators, where the motor experiences a resistance to motion caused by the interaction of the rotor and the stator teeth. This effect can lead to vibrations and may hinder the smooth operation of the machine. In the case of permanent magnet motors, cogging is often experienced due to the magnetic attraction between the rotor magnets and the stator, creating a non-uniform torque. Engineers strive to minimize cogging in design phases to enhance performance.
Synonyms
Examples of usage
- The cogging in the electric motor caused it to operate inefficiently.
- To reduce cogging, we need to optimize the rotor design.
- The technician measured the cogging torque to assess motor performance.

Origin of 'cogging'
Main points about word origin
- The word 'cog' originates from the Old Norse word 'köggr', referring to a tooth on a gear.
- Cogs were used in ancient machinery and illuminated how mechanical functions evolved over centuries.
- The term 'cogging' in engineering dates back to at least the 19th century, as machines became more complex.
The term 'cogging' originates from the English word 'cog,' which has its roots in the Old Norse word 'kogg,' meaning a small boat or a cogwheel, and is related to the concept of interlocking gears or mechanical components. The usage of 'cogging' in engineering contexts began to be more common in the 20th century as electric motors and generators became prevalent in industrial applications. The term reflects the challenges faced in achieving smooth motion and operation in complex mechanical systems, particularly with the rise of precision engineering practices. Over the years, the understanding of cogging has evolved, leading to advancements in technology and design methodologies aimed at minimizing its effects.
