Halbach/수직 자화 영구자석을 갖는 Tubular 모터의 특성해석

Characteristic Analysis of Tubular Linear Motor with Halbach and Vertical Magnetized PMs

In the machine tool industry, direct drive linear motor technology is of increasing interest as a means to achieve high acceleration, and to increase reliability [1]. In this paper, we analyze and compare the characteristics of tubular motor with halbach and vertical magnet array respectively. We derive magnetic field solutions due to the PMs and to the currents. Motor thrust is then derived. The results are shown in good conformity with those obtained from the commonly used finite element method.
