<p>PROBLEM TO BE SOLVED: To obtain a reliable and compact rotor state-detecting device. SOLUTION: The detector 1 is provided with an inner lid 5 that is rotated together with a rotary shaft 50, an outer lid 6 whose rotation is prevented by a weight 7 and a bearing 8, a generator 9 containing a coil 10 being provided at the inner lid 5 and a magnet 11 being provided at the outer lid 6, and a circuit unit 13 and a light-emitting device 17 for transmitting the detection result of a vibration sensor 12. The need for wiring and a slit ring is eliminated, thus improving reliability and miniaturizing the device.</p> |
