Abstract

The present invention relates to a two-phase, two-row linear pulse motor propulsion system, in particular to a two-phase, two-phase two-phase motor that improves acceleration performance and torque characteristics and can realize high-speed driving, stopping, and forward / backward direction conversion functions through non-adhesive driving characteristics. A linear pulse motor propulsion system for columns, the system includes: excitation units (121, 122), which are arranged in two columns along the length direction at the bottom of the mobile body (110), and generate a magnetic field; armature units (131, 132), which It is installed on the running track and generates a moving magnetic field by the power supplied from the power conversion device, and the excitation units (121, 122) of the two rows are respectively arranged in two rows, so that through the interaction based on the two-phase synchronous signal To generate the driving force of the mobile body (110), the system can increase the driving force and improve the performance of high-speed driving and acceleration and deceleration compared with a linear propulsion system with a single-phase arrangement.

Description

technical field [0001] The present invention relates to a two-phase, two-row linear pulse motor propulsion system, in particular to a two-phase, two-phase two-phase motor that improves acceleration performance and torque characteristics and can realize high-speed driving, stopping, and forward / backward direction conversion functions through non-adhesive driving characteristics. Linear pulse motor propulsion system for the column. Background technique [0002] Generally, the acceleration and deceleration performance of railway vehicles is set in consideration of the weight of the vehicle and the performance of the driving device. In the case of many stations in our country, improving the acceleration and deceleration performance becomes the key to shortening the operation interval and the overall time required. [0003] Since a general railway vehicle uses an adhesion drive method as a wheel-on-rail system, there is a speed limit when the adhesion exceeds the upper limit (app...
