Title: ROTOR, ROTARY MOTOR, AND COMPRESSOR
Abstract:
The present invention comprises a laminate core (20) in which a plurality of cores (2) are laminated, permanent magnets (21) disposed in magnet holes (26) formed in an axial direction (Y), and end plates (100, 101) at both ends in the axial direction (Y), and is such that the magnet holes (26) are formed in a plurality in a circumferential direction (Z) and have empty spaces (261) at both ends in the circumferential direction (Z) of the magnet holes (26); flow holes (22) are formed between the magnet holes (26) adjacent in the circumferential direction (Z), inward (X2) in a radial direction (X) from the magnet holes (26) and passing through in the axial direction (Y); each of the cores (2) is provided with a first groove section (24) by which the empty spaces (261) and the flow holes (22) communicate, and a second groove section (25) by which the empty spaces (261) and the outer circumference of the core (2) communicate and which acts as a discharge port; and the end plates (100, 101) are provided with first holes (12) which serve as air intake ports through which the flow holes 22 are exposed, and tab sections (11) which aid in air intake downstream of the first holes (12) in a rotation direction (Z1).
