Abstract

This application provides a bearing device (1), and a motor (2) and a compressor (3) including the bearing device (1). The bearing device (1) includes a rotating shaft (101), a first bearing (102) and a second bearing (103) disposed around the rotating shaft (101) and parallel to each other, a thrust disc (104) sleeved on and fixed to the rotating shaft (101), and a sensor disc (105) disposed around the rotating shaft (101) and parallel to the thrust disc (104). A first displacement sensor (106) including a first sensor probe (1051) and a second displacement sensor (107) including a second sensor probe (1052) are symmetrically disposed on the sensor disc (105). By connecting the first displacement sensor (106), the second displacement sensor (107), and an excitation source module (108, 109, 110) in parallel or in series, detection results of the first sensor probe (1051) and the second sensor probe (1052) are combined to obtain a degree of deviation of the rotating shaft (101), which avoids an error in the parallelism that may occur when one displacement sensor or one sensor probe is used alone.
