Abstract
After finding the harmonic components by measuring the thrust force, which affects high accuracy position control during micro-step drive of LPM, the exciting current was calculated to remove them. Also the detent force being induced by magnetic flux density of permanent magnetic was measured. It was comfirmed that the tooth and slot width was designed properly thresh the analysis of detent force.
