PROBLEM TO BE SOLVED: To provide a non-contact measuring device of rotor temperature which can use easier means to achieve accurate and reproducible result while avoiding conventional defects. SOLUTION: This invention is associated with non-contact measuring device of rotor temperature. This device comprises rotor and stator, magnet on the rotor and electrical coils allocated on the stator, electronic means for measuring voltage applied to these coils, and drive unit for rotating the rotor. In order to allow an improved temperature measurement which also enables measuring within the temperature limits, it is proposed that voltage induced into the coil by the magnet should be measured and that this voltage should be converted into signal proportional to temperature.
