Abstract

In this paper, we propose a new type of tubular linear induction motor (TLIM) with two-dimensional motion. The proposed motor consists of plural short primary LIMs arranged on the same circumference and a common secondary. By adopting independently energized ring-windings to the primary, we can achieve both the reduction of coil-end region and the freedom of alternating current supply. The secondary conductor is capable of producing any one of rotary, linear, and helical motions by controlling the phase of supply currents in each primary winding. From the three-dimensional (3-D) finite element analysis and the experiment, we derive the primary scheme to increase the subsidiary rotary-force. In addition, we deduce an optimal arrangement of the primary slot currents enhancing the secondary thrust in the short primary LIM.
