Abstract
A magnet temperature information output device includes a first element provided on a rotor, a second element provided on a stator, an electric resistance element, and an output section. The first element includes a temperature sensitive element and a first coil. In the temperature sensitive element, electric resistance changes responding to a temperature of the permanent magnet. The first coil is electrically connected to the temperature sensitive element. The second element includes a second coil. The second coil is arranged to be magnetically coupled to the first coil. The electric resistance element is electrically connected to the second element. The output section is electrically connected to the second element and the electric resistance element. The output section is arranged to output an electric signal responding to a magnitude of a voltage drop occurring in the electric resistance element as temperature information regarding the temperature of the permanent magnet.
