Abstract
A magnet temperature information output device is disposed on a rotating electrical machine including a stator and a rotor with a permanent magnet, and is arranged to output temperature information regarding a temperature of the permanent magnet. The magnet temperature information output device includes an element arranged to detect a magnetic flux and output an electrical signal responding to the detected magnetic flux as the temperature information. The element is disposed on the stator.
