LEVITATION SYSTEM Russian patent published in 1995 - IPC

FIELD: magnet suspension vehicles. SUBSTANCE: system has levitating object, ferromagnetic support 1 with concentrator 2 installed above object, cup 4, permanent magnet 6 with concentrator 7 and two circuits for automatic control of clearance and position of cup 4. Clearance control circuit has pickup 8, regulator 9 and electromagnet 3. Position control circuit of cup 4 has electromagnet mean current pickup 11, regulator 12 and drive 13. Drive is mechanically coupled with cup 4. Clearance pickup 8 is installed on end face plane of cup 4. First circuit provides constant clearance between concentrator 2 and pickup 8. Second circuit provides zero level of electromagnet mean current at changing mass of levitating object. EFFECT: enlarged operating capabilities. 2 cl, 1 dwg
