Eddy current radial sensor, magnetic suspension bearing assembly and compressor

The invention provides an eddy current radial sensor, a magnetic suspension bearing assembly and a compressor. The eddy current radial sensor comprises a plurality of block structures which are sequentially arranged in the circumferential direction, the block structures are spliced to form an annular sensor shell (1), the sensor shell (1) comprises an inner ring wall (3) and an outer ring wall (4), a mounting groove (2) is formed between the inner ring wall (3) and the outer ring wall (4), a first radial detection hole (5) is formed in the inner ring wall (3) in the radial direction, and a second radial detection hole (6) is formed in the outer ring wall (4) in the radial direction. And a radial probe (6) is arranged in the first radial detection hole (5). According to the eddy current radial sensor, the axial size of the sensor can be reduced, the space is saved, and the mounting structure is simplified. 本发明提供了一种电涡流径向传感器、磁悬浮轴承组件和压缩机。该电涡流径向传感器包括多个沿周向依次排布的分块结构，多个分块结构拼接形成环形的传感器壳体(1)，传感器壳体(1)包括内环壁(3)和外环壁(4)，内环壁(
