Novel flexible printed circuit windings for slotless linear motor design

Linear motors has been developed for factory automation, transportation applications, and so on. As the trend toward compact sizes in micro electronic products, the required motor drives in these applications need to be downsized with increased power densities. It appears that the winding of miniature linear motor is the most awkward part to be scaled down from conventional motor design when miniaturizing. This paper presents an alternative design for the slotless linear motors. A novel flexible printed circuit winding has been applied to obtain a simplified but qualified result. Having explained the prototyping and inspection, a discussion is given to examine the achievement of this study.
