Embodiment Construction
[0020] specific implementation plan
[0021] Such as figure 1 and figure 2 As shown, a rotary modulation radial spherical pure electromagnetic bearing mainly includes: four stator cores 1, coils 2, sleeves 3, air gaps 4, rotor 5, and stator mountings placed along the ±X and ±Y directions. Disc 6, rotation modulation rotor bearing sleeve 7, rotation modulation bearing 8, rotation modulation rotor lock nut 9, ultrasonic motor rotor 10, ultrasonic motor stator 11, rotation modulation stator bearing sleeve 12 and rotation modulation stator lock nut 13. Among them, the radial bearing coil 2 is wound on the two magnetic poles of each stator core 1, the radial inner side of the four stator cores 1 is the rotor 5, a radial magnetic air gap 4 is formed between the stator core 1 and the rotor 5, and the stator The radial outer side of the iron core 1 is the sleeve 3, the sleeve 3 is fixedly connected with the stator mounting plate 6 by screws, the axial outer side of the stator mount...
