Abstract:
A rotary machine includes a shaft (58) rotatably arranged and having a coolant
channel (45) where a coolant can flow; a container hole (24A) which can contain
a permanent magnet (31A); and a permanent magnet (31A) arranged inside the container
hole (24A). The rotary machine further includes: a rotor fixed to the shaft (58);
and an end plate (29) arranged at a rotor axial direction end (10a); a coolant channel
(43) formed in the end plate (29) and communicating with the coolant channel (45)
via an axial direction end (31a) of the permanent magnet (31A) so that a coolant
can flow; and resin (26) which closes the space between openings (25a, 25b) of
the container hole (24A) positioned at the rotor axial direction ends (10a, 10b)
and the permanent magnet (31A) so as to suppress intrusion of the coolant into
the container hole (24A).
