Title:
LINEAR MOTOR-BASED DARK RAIL ELECTRIC RAILCAR DRIVING AND CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/004894
Kind Code:
A1
Abstract:
Disclosed is a linear motor-based dark rail electric railcar driving and control system. In the system, a high-strength magnet and a magnetic yoke are mounted on a railcar, and a wire, a magnetic sensor, a magnetic yoke and a driving module are mounted on a rail; the position of the railcar is sensed by means of the magnetic sensor, so as to control current conduction in the wire; the railcar is pushed to drive forward by using an interaction force between the high-strength magnet and an electrified wire; and the speed of the railcar and the winding structure of the wire are controlled by controlling current conduction time, so that the electric railcar can automatically correct the direction thereof. The present invention greatly reduces structural complexity of a railcar, thereby greatly reducing the cost and weight of the railcar and improving the reliability of the operation thereof, thereby enabling the railcar to be widely applied, thus achieving personal rail transit travel in suburban areas, greatly reducing the emission of polluting gases from fuel vehicles, and preventing environmental pollution brought about by the production and scrapping of batteries of electric vehicles.
