[0019] specific implementation plan
[0020] Such as figure 1As shown, a rotationally modulated axial spherical pure electromagnetic bearing mainly includes: an upper stator core (1-1), a lower stator core (1-2), an upper axial bearing coil (2-1), a lower axial Bearing coil (2-2), rotor (3), upper axial air gap (4), lower axial air gap (5), stator mounting plate (6), rotation modulation rotor bearing sleeve (7), rotation modulation bearing (8), rotation modulation rotor lock mother (9), ultrasonic motor rotor (10), ultrasonic motor stator (11), rotation modulation stator bearing sleeve (12) and rotation modulation stator lock mother (13). The upper axial bearing coil (2-1) is wound in the cavity of the upper stator core (1-1), and the lower axial bearing coil (2-2) is wound in the lower stator core (1-2), A rotor (3) is formed between the upper stator core (1-1) and the lower stator core (1-2), and an upper axial air gap (4) is formed between the upper stator core (1-1) and ...
