As its arrangement mode and Distribution of Magnetic Field mode.According to the suspending efficiency of every meter of Halbach type tracks of permanent magnetism of calculating up to single peak type
2.85 times of tracks of permanent magnetism, but its cost is only the 38% of single peak type tracks of permanent magnetism., the tracks of permanent magnetism based on Halbach array,
Cost is reduced while ensureing that magnetic floats car even running.
Electromagnet 1 includes in track switch：Iron core and coil, iron core include four branches, and four branches are from left to right successively
It is arranged side by side, one end of the same side, which is collected, to be integrated, and the other ends of the Liang Ge branches to keep left extends magnetic pole A after collecting, and keeps right
Liang Ge branches the other end collect after extend magnetic pole B；A coil, four coil connections are wound in each branch；Keep left
Liang Ge branches on coil energization direction it is different with the coil electricity direction in the Liang Ge branches to keep right；Two points to keep left
Coil electricity direction in branch is identical；The coil electricity direction in Liang Ge branches kept right is identical.The special construction of the iron core, it is left
The iron core of right branch accumulates two magnetic poles respectively, on the one hand effectively guides in magnetic field to magnetic pole, is formed in some turn-out track direction
On uniform magnetic field, on the other hand, for the design with respect to three magnetic poles reduce production cost.Multiple coils are used to produce
Bigger magnetic flux density.
Corner's design to iron core in existing Conventional monomodal type tracks of permanent magnetism magnetic turnout electromagnet is unreasonable, existing
Iron core corner be right angle, easily produce leakage field.And leakage field phenomenon make it that increase raceway surface magnetic flux density is more difficult.It is right
It is improved, and at the iron core corner design obtuse angle and chamfering of electromagnet, reduces leakage magnetic flux, increases magnetic caused by electromagnet
Flux density.
In view of the particularity of magnetic turnout electromagnet, the electromagnet, which uses, has high saturated magnetic induction and high magnetic conductance
The ferrocobalt of rate, coil use copper coil, further increase magnetic flux density caused by electromagnet.

A and magnetic pole B is in the center of turnoff, therebetween the space of alternate one piece of permanent magnet size.In Y-shaped track,
By being passed through the electric current of different directions in magnet spool, the uniform flux density in some specific direction is formed, is guided
Magnetic suspension train uses Nd-Fe-B permanent magnet towards direction turn-out track, tracks of permanent magnetism, is Halbach type tracks of permanent magnetism, has extremely strong
Poly- magnetic energy power, be so far can by minimum permanent magnet dosage produce most high-intensity magnetic field track arrangement mode.
Need continuously to run on track switch model in view of levitation vehicle, linear electric motors, straight line are also provided with track switch model
Motor is arranged on the tracks of permanent magnetism of the upper at least one bifurcated connection of at least one track switch.It can realize that magnetic floats by linear electric motors
Driving, acceleration and deceleration of car etc. automatically control.
It is suspended in addition, magnetic floats car on tracks of permanent magnetism, when linear electric motors drive its operation, only by air drag and rail
The influence of road Magnetic field inhomogeneity.When using linear electric motors ramp to stop, slow parking can only be realized, parking spot is not fixed.
To reach the purpose of stopping a train at a target point, in orbit there is provided more than one stop and parking magnet coil, stop electromagnetic wire
Circle is arranged on stop.It is powered before magnetic floats car arrival stop to corresponding magnet coil and then produces magnetic field, magnetic floats car
Parking sensor when reaching stop on roof, the tablet (small iron plate) that also known as stops are realized stopping a train at a target point by magnetic field suction.
Automatically controlling for magnetic turnout can not be realized based on currently employed " Y " font track switch model, it is impossible to monitoring in real time
Magnetic floats the running position of car and then controls the start and stop of track switch electromagnet and linear electric motors.For guarantee electromagnet and linear electric motors
Reason, electromagnet and the linear electric motors such as trouble free service, the saving energy should be initially powered up when dolly will pass through track switch.For
This, in addition to：Sensor is respectively provided with multiple position sensors, the trunk of track switch and the tie point of branch and tracks of permanent magnetism.
Track switch trunk and branch can be understood as separating multiple branches from a trunk, certainly in other examples
Can be by trunk and branch exchange, without clear and definite trunk or branch, branch's relation between circuit is similar, branch's relation,
For position in whole track switch, trunk both can be understood as, it is understood that be branch to a circuit.
Its Position Sensor can be infrared emission sensor, and it floats car condition monitoring unit as magnetic, in real time
The running position that magnetic floats car is monitored, the suspension truck position detected using it effectively controls the energization situation of electromagnet.Work as magnetic
When floating car will pass through track switch position, just it is powered to electromagnet, realizes that magnetic floats the commutation of car；When magnetic floats car without sensor,
Electromagnet powers off.This intermission power supply method, it is possible to prevente effectively from electromagnet seriously generates heat and then dropped caused by lasting be powered
The problem of low self-characteristic, while reach the purpose for saving electric energy.
In order to give full play to the effect of position sensor, each branch that can be on track switch is set, can also be in straight line
Motor both sides is set.Such as：Track switch is in " Y " font, and linear electric motors are arranged at the tracks of permanent magnetism of the two bifurcated connections in " Y " left and right
On.And sensor is infrared emission sensor, in tracks of permanent magnetism both sides, two sensors of arrangement are one group, and one of them is
