Description
Technical field:
The invention belongs to the suspension magnet structure and the manufacturing technology thereof of normal conducting electromagnetic levitation technology vehicle.
Background technology:
Maglev vehicle can be divided into electromagnetic suspension (EMS-electromagneticsuspension) and electrodynamics suspension (EDS-electrodynamic suspension) two classes on suspension mechanism.Electromagnetic suspension (EMS) is that vehicle-mounted levitating electromagnet (or permanent magnet adds the excitation control coil) energising excitation is generated an electromagnetic field, ferromagnetic component on electromagnet and the track (steel track or long-stator linear motor stator core) attracts each other, train upwards picked up be suspended on the track the general about 8～10mm of the levitation gap between electromagnet and the ferromagnetic track.Electrodynamics suspension (EDS) is could suspend when train reaches certain speed.When train movement, produce inducing current in the suspended coil of the moving magnetic field of the magnet of installing on the train on being installed on circuit, both mutual actions produce a magnetic force that makes progress and train is suspended in the road surface certain altitude (is generally 100～150mm).
Electromagnetic suspension (EMS) train is representative with the TR08 of Germany and the HSST-100L type of Japan, sees patent for details: CN1456458A, CN1273189A, US6753666B2, US4641586, US5152227.
