Title:

TWO-PHASE TWO-COLUMN LINEAR PULSE MOTOR PROPULSION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2014/054853

Kind Code:

A1

Abstract:

The present invention relates to a two-phase two-column linear pulse motor propulsion system, and more particularly, to a two-phase two-column linear pulse motor propulsion system which can implement a high-speed driving function, a stopping function, and a front/rear switching function through non-adhesive characteristics by improving acceleration performance and torque characteristics, comprising: a field unit (121, 122) prepared in two columns toward the longitudinal direction at a lower part of a moving body (110) so as to generate a magnetic field; and an armature unit (131, 312) which is prepared on a traveling track, generates a moving magnetic field by the power supplied from a power conversion device, is prepared in two columns so as to correspond to the two-column field unit (121, 122), and generates the propulsion of the moving body (110) through an interaction due to a two-phase synchronous signal, wherein the propulsion thereof can be improved in comparison with a linear propulsion system having a single phase arrangement and the high-speed driving and acceleration and deceleration performance can be increased thereby.
