常状態を早期に知ることができ、装置全体の致命的な損
傷を防止することが可能となる。In such a structure, for example, if a rope or the like is wrapped around the propeller, an abnormal thrust will be generated in the bearing portion, which will increase the temperature of the bearing portion. Also,
The same is true when the bearing runs out of lubricating oil or when the output shaft is misaligned and abnormal wear occurs.In such cases, detecting the temperature of the bearing can quickly detect abnormal conditions. This makes it possible to prevent fatal damage to the entire device.
