Novel Flexible Printed Circuit Windings for a Slotless Linear Motor Design

Abstract

-Linear motors has been developed for factory automation, transportation applications, among other applications. As the trend toward compact sizes in micro electronic products progresses, the required motor drives in these applications need to be downsized with increased power densities. It appears that the winding of miniature linear motors is the most awkward part to be scaled down from conventional motor designs when miniaturizing. This paper presents an alternative design for 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.

Wind Micro-Turbine Networks for Urban Areas: Optimal Design and Power Scalability of Permanent Magnet Generators

“…An axial flux single phase iron-less PM generator with PCB stator is proposed in [21], with the aim of developing a zero cogging torque solution for small marine energy conversion systems. In [22] a novel flexible PCB winding for a slot-less linear PM motor is investigated and an original configuration made of rhomboidal and triangular coils is proposed in order to reduce the end-windings. A further example is proposed in [23], where the armature of a double-sided linear brushless DC motor is constituted by PCB coils in order to reduce the mechanical time constant and to improve the dynamic performance of the machine.…”
