Definitions for "Cogging"
This term refers to the typically undesirable property of conventional DC motors to assume a preferred rotor position due to the change in reluctance in the slot wound laminated iron rotor. This means that accurate positioning is simpler and more accurate with a coreless motor and operation is smooth even at low speed.
A condition in which a motor does not rotate smoothly, but "steps" or "jerks" from one position to another during shaft revolution.
The cyclic physical resistance felt in some alternator designs from magnets passing the coils and gaps in the laminates. Detrimental to Start-up.
