Abstract:
A magnet temperature estimation device for a rotating electric machine includes a rotating electric machine configured with a rotor having a magnet and a stator having a coil, a coolant supply part configured to supply a coolant flowing from the stator toward the rotor, and a magnet temperature calculation part configured to calculate a temperature of the magnet using a temperature of a coolant that receives heat from the coil.
