Characteristics Analysis and Magnetic Circuits of Various Kinds Linear Pulse Motor

각종 리니어펄스모터(LPM)의 자기회로와 그 특성해석

Recently, in the industrial applications, the direct drive method with linear pulse motor(LPM) has been introduced and studied for practical use. This paper describes the analysis result of hybrid(HB), permanent magnet(PM), and variable reluctance(VR) type LPM. First, calculation of the flux density distribution in the air gap at these LPM by finite element method. And by mean of Maxwell's stress tensor with above magnetic flux density, calcurated the static thrust force and normal force.
