Development and Evaluation of Surface Motor Using Halbach-Type Magnet

Abstract

Several types of surface motors (SFMs), which have the ability to perform surface motion, have been proposed. We have proposed a new type of SFM using Halbach-type permanent magnet that does not require wires to be connected to the mover. The feature of this new type of SFM is that the mover can perform rotation in addition to linear motion on a plane surface. In this letter, the structure, the movement principle, and the characteristics of the proposed SFM using Halbach-type permanent magnet are investigated.
