Abstract

ABSTRACT A rotating electrical machine (1) comprises a stator (2) and a rotor (3) including a rotor iron core (20) in which a permanent magnet (21) is disposed. The rotor iron core (20) comprises a connection part (20A) configured to surround a rotational axis (10), a plurality of magnetic pole parts (20B) provided in an outer portion than the connection part (20A) in a radial direction, a first gap (20b) configured to penetrate along an axial direction between the magnetic pole parts (20B) in an outer portion than the connection part (20A) in the radial direction and in which the permanent magnet (21) is fixed with adhesive, and a second gap (20c; 20e; 20f; 20g) for injection of the adhesive, at least one of the second gaps being provided for each of the first gaps (20b) in communication with the first gap (20b).
