This disclosure discloses a rotary electrical machine of a variable field type configured to change a field magnetic flux. The rotary electrical machine includes a stator including stator windings and a stator core, and a rotor including a shaft rotatably supported, a rotor core relatively rotatably mounted on the shaft, and a plurality of first permanent magnets disposed on the rotor core. The rotor core is configured to be held at a predetermined angular position with respect to the shaft with a magnetic suction force of the first permanent magnet, and to increase a relative angle with the shaft in response to an increase of a load torque against the magnetic suction force. The rotor core has an approximately same axial length as the stator core.
