SOCKET NON-CONTACT ELECTRIC MACHINE Russian patent published in 1997 - IPC

FIELD: electric engineering. SUBSTANCE: each pole of pole system is designed as pair of magnetically soft prism-shaped bars 5, 6, which are shifted along axial rotor length and have permanent magnets 7-16. Cores 4 of first pole system are located inside magnetically soft rings which are tightly pressed against poles of second pole system and function as by-passes of magnets 9, 11. This results in maximal possible concentration of magnetic flux due to use of all non-working sides of prism-shaped bars of second p-pole system of rotor. In addition rings provide rigid connection of pole systems to rotor hub. EFFECT: decreased weight, increased reliability. 3 dwg
