cogging
A term used to describe non-uniform angular velocity Cogging appears as a jerkiness especially at low speeds
Non-uniform or erratic rotation of a direct current motor It usually occurs at low speeds and may be a function of the adjustable speed control or of the motor design
The cyclic physical resistance felt in some alternator designs from magnets passing the coils and gaps in the laminates Detrimental to Start-up
Cogging refers to shaft rotation occurring in jerks or increments rather than smooth continuous motion The non-uniform (“jerky”) rotation results from the armature’s propensity to certain discrete angular positions The interaction of the armature coils entering and leaving magnetic fields, produced by the field coils or permanent magnets, causes speed changes The armature tends to speed up and slow down as it cuts through the fields during rotation Cogging is very apparent at low speeds, and determines a motor’s speed range
A condition in which the motor does not rotate smoothly, but steps from position to position while rotating This may occur at very low speeds when the motor is driven by an adjustable frequency drive
A condition in which a motor does not rotate smoothly but "steps" or "jerks" from one position to another during shaft revolution Cogging is most pronounced at low motor speeds and can cause objectionable vibrations in the driven machine
