Abstract

We propose a spiral-type motor that has high thrust characteristics as a linear actuator. This motor generates torque around the axis and thrust in the axial direction only by electromagnetic force. It has little friction because no additional hardware is required for straight-line movement. This paper presents the concept of the spiral motor. The finite-element method (FEM) analysis certifies that this motor has high motor constant as same as High Density Linear Motor (HDL). We also study a method to compensate the thrust fluctuation of 5-pitch-stator 6-pitch-mover model
