In order to satisfy the smoothness of thrust of flat three-phase permanent magnet linear synchronous motor(PMLSM)
factors and regularity of its end force and slot force are analyzed through finite element method.A method to measure the detent force in the right and left direction according to reciprocating movement on the whole stroke is introduced
which can eliminate the effect of the friction force
and the experiment is carried out on an optimized prototype.TMS320F2812 digital signal processor(DSP) collected the signal of force-transducer and encoder.After calculation
detent force as a function of displacement is acquired accurately and rapidly
and the measurement error can be within 3 N.The results of experiment justify the validity of the analysis model
which is useful for the further design of high performance servo controller of PMLSM.
