Medium-low speed maglev train and linear motor mounting structure thereof

Abstract

The invention relates to a linear motor mounting structure of a medium-low speed maglev train, which comprises a motor stator and a motor beam arranged on a support arm, and further comprises a statorfloating mounting assembly for mounting the stator on the motor beam, the stator floating mounting assembly comprises a mounting hole formed in the motor beam, and the axis of the mounting hole is parallel to the vertical direction; the sleeve is fixed in the mounting hole, and a stepped hole is formed in the sleeve; the screw rod is sleeved with a spring, the screw rod penetrates into the sleevefrom the top end of the mounting hole, one end of the spring abuts against the step of the step hole, the other end of the spring abuts against an end cap of the screw rod or abuts against a nut mounted at the top of the screw rod, the screw rod can freely move up and down in the mounting hole, and the motor stator is hoisted at the lower end of the screw rod. The linear motor mounting structurecan automatically adjust the gap between the motor stator and the motor rotor according to different working conditions, so that the efficiency of the motor is improved, and the comprehensive energy consumption of a maglev train is reduced. The invention further discloses a medium-low speed maglev train.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of maglev trains, in particular to a medium-low speed maglev train and a linear motor installation structure thereof. Background technique [0002] The speed of maglev train can be divided into low speed, medium speed and high speed. The speed of low speed maglev train is below 125km per hour, which is mainly suitable for urban public transportation. The speed of medium speed maglev train is about 250km per hour, which is mainly suitable for suburban passenger transport. The speed of the train is about 500km per hour, and it is mainly used for high-speed passenger transportation between large cities with long distances and large passenger flow. [0003] Medium and low-speed maglev trains are driven by short-stator linear asynchronous motors. The short-stator linear asynchronous motors are composed of a short stator installed on the train and a rotor (aluminum reaction plate) on the ...

AI Technical Summary

Problems solved by technology

[0003] Medium and low-speed maglev trains are driven by short-stator linear asynchronous motors. The short-stator linear asynchronous motors are composed of a short stator installed on the train and a rotor (aluminum reaction plate) on the track. The gap between the pole surface of the rotor and the rotor is 13±4mm, and the gap between the stator and the rotor is relatively large, such as figure 1 As shown in , at present, the stator 04 of the linear motor in the maglev train is fixedly installed on the motor beam 02 through the screw rod 03, the rotor 05 is located above the electromagnet 06, the motor beam 02 is installed on the support arm 01, and between the stator 04 and the rotor 05 The gap cannot be adjusted according to the real-time operating conditions of the train, which leads to low efficiency of the linear motor, which is not conducive to energy saving and consumption reduction and the speed increase of the train
