Formulation, measurement and analysis for the thrust force of HB-type Linear Pulse Motor

The linear motor is available for linear transition motion, because of its advantages, the motor design and its application have gradually increased, but the quantitative measurement system of thrust force has not been generalized. Need analysis of correct thrust for control performance improvement of HB-LPM (HB-type linear pulse motor). It is difficult to analyze HB-LPMpsilas thrust. In this paper, HB-LPMpsilas thrust is expressed to mathematical expression. And it is proved validity of this numerical formula by thrust measurement system. Two phase driver is composed. It is verified validity of numerical formula that measure waveform of electric current and voltage that is supplied in each phase.
