Title:
RAIL TRANSIT TRACTION SYSTEM BASED ON FLUX-SWITCHING PERMANENT MAGNET LINEAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/151174
Kind Code:
A1
Abstract:
Disclosed in the present invention is a rail transit traction system based on a flux-switching permanent magnet linear motor. The rail transit traction system based on the flux-switching permanent magnet linear motor is composed of a plurality of subsystems. The subsystems of the urban rail transportation traction system based on the flux-switching permanent magnetic linear motor comprise a car, a rail, and a direct current power supply system. The car comprises a car body, bogies, i*2p primaries of the permanent magnet flux switching linear motor, an inverter, and a motor controller. The rail comprises a train guide rail and a secondary of the flux-switching permanent magnet linear motor. j*2q subsystems of the urban rail transit traction system based on the flux-switching permanent magnet linear motor constitute one whole traction system. The present invention features a simple secondary structure, high system efficiency, and a high system power factor, and rules for the setting of distance between primaries of the permanent magnet flux-switching linear motor in the traction system are provided. Fluctuations in system traction can be effectively reduced, thereby reducing noise during train operation, and improving stability.
