Title:
VIBRATION PIEZOELECTRIC SENSOR AND DEVICE FOR CHECKING MOTOR OPERATING STATE BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/099458
Kind Code:
A1
Abstract:
A vibration piezoelectric sensor and a device for checking a motor operating state by using the same are provided. The device for checking an operating state of a motor, according to the present invention, comprises: a main body; a vibration piezoelectric sensor accommodated in the main body so as to sense vibrations generated from the motor, and converting the sensed vibrations into electrical energy; a rectification unit accommodated in the main body so as to convert the electrical energy into a direct current; a direct current power output unit accommodated in the main body so as to output the converted direct current power; and an operating state notification unit for notifying of an operating state of the motor by using the outputted direct current power.
