ROTARY MACHINE

摘要

A rotary machine (100) includes: a stator (12); a rotor (20) inserted into the stator (12) and rotatably supported; a magnet reception unit (32) formed in the rotor (20); a permanent magnet (22) mounted in the magnet reception unit (32); a hole (31) arranged apart from the magnet reception unit (32) and extending in the axis direction; an end plate (23) arranged at the end surface of the axial direction of the rotor (20); a channel (33) defined by at least one of the axial direction end surface and the end plate (23) and leading from above the opening of the hole (31) to above the axial direction end surface of the permanent magnet (22); and a discharge exit defined by at least one of the axial direction end surface and the end plate (23) of the rotor (20) so as to communicate with the channel (33).
