PROBLEM TO BE SOLVED: To provide a rotor, a motor, and a compressor capable of maintaining a yield at a manufacturing step.SOLUTION: A rotor 10 comprises a rotor core 20 and an end plate 30. The rotor core 20 is in a columnar shape having an upper surface, a lower surface, and a central axis C. The end plate 30 covers the upper surface or the lower surface of the rotor core 20. The rotor core 20 is formed with a shaft holding hole 21 and a fluid passage 22. The shaft holding hole 21 has a circular cross section using a point on the central axis C of the rotor core 20 as the center, and extending in a direction in which the central axis C extends. The fluid passage 22 extends in parallel to the central axis C of the rotor core 20. An opening formed on the end plate 30 includes a shaft passing opening and a recessed part. The shaft passing opening is communicated with the shaft holding hole 21. The recessed part is communicated with the fluid passage 22, and extends radially outward from the shaft passing opening.SELECTED DRAWING: Figure 1 |
