Document Type and Number:
WIPO Patent Application WO/2020/226128
Kind Code:
A1
Abstract:
This temperature measuring device (80), for measuring the temperature of a rotor (40) in a motor (20), comprises a temperature sensor (82), a transmission unit (73), and a receiving unit (76). The temperature sensor (82) is fixed to the rotor (40) or a rotating body (56) which rotates together therewith, and measures the temperature of a prescribed area (p1) on the rotor (40). The transmission unit (73) is fixed to the rotor (40) or to the rotating body (56) which rotates together therewith, and acquires temperature information (iT) from the temperature sensor (82) and transmits this to outside of the rotor (40). The receiving unit (76) is installed outside of the rotor (40) in a state not rotating together with the rotor (40), and receives the temperature information (iT) transmitted by the transmission unit (73).
