Abstract

This paper presents a magnetic lead screw (MLS) with a simple structure. An MLS is a kind of feed screw that allows noncontact force transmission. However, it has low productivity due to its complicated structure and number of parts. To simplify the structure of the conventional MLS, we propose a consequent-pole MLS (CPMLS). Since a consequent-pole magnetic structure with arc shape permanent magnets is adopted to the model, the complexity and number of parts can be reduced. First, the basic structure of the proposed MLS is described. Then, the static force of the prototype is measured and it is compared with the calculated value. For verifying the operation of the proposed MLS as a lead screw, the linear motion of the nut and the rotation of the screw are measured. From the results, the characteristics of the proposed MLS is discussed.
