To accurately obtain the temperature of a rotor and the tendency of variation in the temperature of the rotor.SOLUTION: A temperature measuring device 80 for measuring the temperature of the rotor 40 of a motor 20 includes a temperature sensor 82, a transmission part 73 and a receiving part. The temperature sensor 82 fixed to the rotor 40 or a rotating body 56 rotating therewith measures the temperature of a predetermined portion p1 of the rotor 40; the transmission part 73 fixed to the rotor 40 or the rotating body 56 rotating therewith obtains temperature information iT from the temperature sensor 82 to transmit to the outside of the rotor 40; the receiving part installed in the outside of the rotor 40 in a state without rotating together with the rotor 40 receives the temperature information iT transmitted by the transmission part 73.SELECTED DRAWING: Figure 2

    【課題】ロータの温度やロータの温度変化の傾向を、精度よく取得できるようにする。【解決手段】温度計測装置80は、モータ20のロータ40の温度を計測する装置であって、温度センサ82と送信部73と受信部とを有する。温度センサ82は、ロータ40又はそれと共に回転する回転体56に固定されており、ロータ40の所定部分p1の温度を計測する。送信部73は、ロータ40又はそれと共に回転する回転体56に固定されており、温度センサ82から温度情報iTを取得して、ロータ40の外部に送信する。受信部は、ロータ40の外部にロータ40と共に回転することのない状態で設置されており、送信部73により送信された温度情報iTを受信する。【選択図】 図2
