STATE MONITOR
Document Type and Number:
Japanese Patent JP2017204217
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a state monitor for monitoring a state such as vibration acceleration and temperature of a rotating body capable of obtaining desired electric power in a non-contact manner.SOLUTION: The state monitor attached to a rotating body includes: a magnetic field application part 100a that applies a magnetic field outside of the rotating body; and a power generation part 30 that efficiently generates the power by a movable part which resonates being caused by changes of magnetic field due to rotation of a rotating body. With this, a radio state monitor is achieved, which requires no power supply from a battery and a rotation body outside.SELECTED DRAWING: Figure 3
