Abstract

Provided are a permanent magnet motor with an outer spiral rotor (1) and a wheel-rail vehicle road system with permanent magnet suspension. The permanent magnet motor comprises a stator armature (2), an outer rotor (1), bearings (13) and a control system, in which the outer rotor (1) is an outer spiral rotor, i.e. on the outer rotor (1) spiral blocks (4) having permanent magnets are arranged along a spiral line, the magnetic pole directions of the spiral blocks (4) are in the radial direction of the outer rotor (1) and adjacent magnetic poles are arranged alternately as N and S poles; the stator armature (2) is formed by a stack of stator laminations (7) with a spiral groove (9) arranged along a spiral line, the pitch of the spiral groove (9) being the same as that of the outer rotor (1), and spiral coils (10) are wound inside the spiral groove (9). The permanent magnet motor is provided with an outer spiral rotor (1) outside the motor, thus a greater output of driving power can be obtained with an identical outer diameter. The permanent magnet motor-generator with the outer spiral rotor (1) is suitable for highly efficient driving of a magnetically suspended vehicle and highly efficient braking thereof with power generation and recovery.

Description

technical field [0001] The invention relates to the technical field of electric motors and maglev trains, in particular to a linear motor drive system and a levitation guidance and positioning system for permanent maglev trains. Background technique [0002] The prior art of the linear drive motor of the maglev train adopts a linear synchronous motor or a linear asynchronous induction motor. Due to the reality of practical application, the acceptable minimum gap between the linear motor and the track is at least 8 millimeters, so the efficiency is much lower than that of the existing rotary motor with a magnetic gap of 0.5-1 millimeter. [0003] In industry, three-phase asynchronous motors are simple in structure and easy to maintain, so they are widely used, but there are obvious iron loss and copper loss. Even if the frequency conversion speed control technology is used, there is also the defect of low efficiency at low speed. Permanent magnet synchronous motors have high...
