PROBLEM TO BE SOLVED: To accurately measure a temperature of a moving body.SOLUTION: A temperature measurement device measures a temperature of a rotor 4 of a motor 1 that has the rotor 4 and a stator 6 adjacent to the rotor 4 and formed of the same material as the rotor 4. The temperature measurement device includes: a first non-contact temperature sensor 11 that is installed separately from the rotor 4 and measures a first temperature Tra to be the temperature of the rotor 4; a second non-contact temperature sensor 12 that measures a second temperature Tsa to be the temperature of the stator 6; a thermocouple 13 that is installed on the stator 6 and measures a third temperature Tsb to be the temperature of the stator 6; and a motor temperature measurement unit 21 that integrates a correction coefficient K(Tsb/Tsa) to be a ratio between the second temperature Tsa and the third temperature Tsb to the first temperature Tra, and calculates a temperature Tr of the rotor 4. |
