Abstract
LDM, easy to minute position control, is using as X-Y plotter or other recording instruments. Brushless LDM has better properties than the conventional Brush type LDM in many aspects. This paper presents magnetic flux density distribution by FEM and a way to reduce thrust force ripple particurary in low speed drive. And we apply this method to a real mode of LDM. This LDM is operated by IBM-PC host computer and uses rotary encoder to make position signal.
