摘要:
An attraction type magnetic levitation vehicle system includes a magnetic rail laid on the side of a track and a levitation vehicle having a supporting electromagnet and a guide electromagnet each having a plurality of magnetic poles arrayed along the track. A magnetic pole surface of each of the plurality of magnetic poles is in opposing relationship to a surface of the magnetic rail, respectively. The magnetic pole surface of at least one of the supporting and guide electromagnets and the surface of the magnetic rail opposing the magnetic pole surface is in the form of a rectangular waveform having a plurality of alternating groove-and-teeth pairs arranged at a predetermined pitch. The distances from one of the plurality of magnetic poles each having the rectangular-wave-shaped magnetic pole surface of the remaining magnetic poles are staggered by less than one pitch from an integer multiple of the predetermined pitch. Exciting currents flowing in pulses through exciting coils of the plurality of magnetic poles are controlled to increase in predetermined timing and order, thereby allowing thrust to be produced in the direction of the track.
