Characteristic Analysis of Tubular type Slotless Linear DC Motor

Slotless Tubular type 선형 직류 전동기의 특성 해석

This paper presents the characteristic analysis of slotless tubular type Linear DC Motor with Permanent Magnet excitation as variation of magnetic pole-pitch ratio. The stator armature winding of this motor is designed to wind at inner stator around the mover mounted with permanent magnet. First the practical model of this motor is made and its parameter is measured, after this simulation is carried out. Comparing the simulation results as variation of pole-pitch ratio, it can be seen that the reaching ability makes it useful in applications requiring a small, direct-drive actuator, which is required to extend into a specially constrained environment.
