Embodiment

[0022] Such as figure 1 As shown, a long stator linear motor winding for rail transit, the long stator linear motor winding 1 includes A-phase concentrated winding 2, B-phase concentrated winding 3 and C-phase concentrated winding 4, A-phase concentrated winding 2 arranged in sequence 1. The B-phase concentrated winding 3 and the C-phase concentrated winding 4 are provided with the same coil winding installation grooves, and the coil windings 5 ​​are respectively arranged in the coil winding installation grooves. The total number of coil winding installation slots for the A-phase concentrated winding 2 , the B-phase concentrated winding 3 and the C-phase concentrated winding 4 satisfies the requirement that the number of slots per pole and phase of the long-stator linear motor is a fraction. In this embodiment, there are 9 coil winding installation slots in the long stator linear motor winding 1, and the A-phase concentrated winding 2, B-phase concentrated winding 3 and C-phas...

Abstract

The invention relates to a long stator linear motor winding for rail traffic; the long stator linear motor winding (1) comprises an A-phase concentration winding (2), a B-phase concentration winding (3) and a C-phase concentration winding (4) arranged in sequence; the A-phase concentration winding (2), the B-phase concentration winding (3) and the C-phase concentration winding (4) are provided with same coil winding mount grooves; a coil winding (5) is respectively arranged in each coil wining mount groove, and is a single-layer winding that employs a concentric type winding mode. Compared with the prior art, the winding is simple in layout, easy in terminal wiring, easy to realize modularized design and making, can reduce higher harmonic and electromagnetic noises, can smooth a pushing force, so the vehicle can be more stable in motions; in addition, the single-layer winding conductor is close to an excitation magnetic pole, thus effectively utilizing the excitation field, and improving the motor efficiency.

Description

technical field [0001] The invention relates to a long stator linear motor winding, in particular to a long stator linear motor winding for rail traffic. Background technique [0002] The application of linear drive technology and maglev technology in the field of transportation is a major technological innovation of transportation tools. The characteristics of no mechanical contact and environmental advantages of maglev trains have gradually attracted attention in the field of transportation. The wheel-rail linear drive train combined with traditional wheel-rail and linear drive technology has the advantages of flexible line design, high speed, low energy consumption, low noise and environmental protection, etc. It provides a new way for urban rail transit, bulk cargo transportation and port logistics . [0003] According to the length and installation position of the primary linear motor, the commonly used linear motors for trains can be divided into long-stator linear s...
