Influence of cogging force on solar thermo acoustic generation systems
The Journal of Engineering, 2017 Here, the model of a solar thermoacoustic generation (STAG) system is presented, and the influences of cogging force on the resonance of STAG system are investigated by simulation. The samples of cogging force are taken from three typical linear alternator designs, and their consequent influences on STAG system are described.

RBFNN Based Linear Motor Cogging Force Identification for Lithography Machines
IFAC-PapersOnLine, 2015 Abstract The cogging force of linear motors significantly affects the positioning accuracy in ultraprecision lithography machines. Optimal motor design cannot completely eliminate it, leaving the realtime active compensation as the only means to counteract its adverse effect.
