Problems solved by technology

There is a risk of self-explosion when tempered glass is used as a pipe window. If it is used in a vacuum pipe, even if a piece of tempered glass explodes and shatters, the entire pipe will leak.

[0116] Embodiment 2: permanent maglev highway and permanent maglev bus

[0117] like Figure 18 , Figure 19 Shown, also can only lay this permanent maglev driving track 51 on the urban bus main road, and needn't lay two steel rails, become permanent maglev highway. That is, the outer helical rotor permanent magnet motor generator 38 is arranged coaxially with the helical stator 32 with openings on the outside, and the helical stator 32 penetrates up and down to become two semicircular helical stators 32, each helical stator 32 The outside is provided with a horizontal rib 39 and a vertical rib 40, and the horizontal rib 39 and the vertical rib 40 are L-shaped. A Z-shaped suspension plate 41 is arranged at the bottom of the helical stator 32 . The horizontal ribs 39 on the left and right sides of the helical stator 32 ride on the embedded parts 36 on the shoulders of the concave groove 42, and an adjusting backing plate 37 is arranged between the horizontal ribs 39 and the ...

Embodiment 3

[0122] Example 3: Single-axis drive 4-channel permanent maglev elevated light rail

[0123] like Figure 21 As shown above, the support column 61 is erected on the green belt of the highway, the central line or the corridor on both sides of the road, or the support column 61 is erected on the line of urban planning. A crossbeam 62 is laid on the top of the column, and the crossbeam 62 can be on one side of the column, or the crossbar can stretch out to both sides on the column 61 . A longitudinal box girder 63 is erected on the side of the cross beam 62, and the longitudinal box girder 63 can be a reinforced concrete structure or a steel beam. The top of the longitudinal box girder 63 is connected to the helical stator 32 with openings. A transition beam 64 may also be provided between the longitudinal box girder 63 and the helical stator 32 to facilitate installation. The transition beam 64 is connected to the upper part of the longitudinal box beam 63 , and the bottom of ...

Abstract

The invention provides a permanent magnet motor with an external spiral rotor and a permanent magnet suspension wheeltrack vehicular access system. The external part of the motor is provided with the external spiral rotor, so that larger output power is obtained with the same external diameter. The permanent magnet motor with the external spiral rotor is applied to efficient drive and efficient power generation recovery brake kinetic energy of a magnetic suspension train, can be used for driving a permanent magnet suspension wheeltrack subway, a permanent magnet suspension vehicle and a four-channel elevated railway passenger car, and is used for elevated permanent magnet suspension towing machine to convey cars or trucksin an enegy saving way. Due to the adoption of the elevated bidirectional four-channel permanent magnet suspension wheeltrack high-speed rail, the constructing cost of a permanent magnet suspension high-speed rail can be lower than that of the existing high-speed rail, and a realistic significance is realized on energy conservation of transportation sector and national energy-saving emission reduction.

Description

Technical field [0001] The invention relates to the technical field of motors and maglev trains, in particular to a linear motor drive system and an energy recovery system for a permanent maglev train, especially to an outer rotor permanent magnet motor generator, and to a permanent maglev wheel-rail vehicle road using the motor as traction power system. Background technique [0002] The linear drive motors of maglev trains have always been linear synchronous motors or linear asynchronous induction motors. 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 iron loss and copper loss. Even if the frequency conversion speed control technology is...
