System for determining the cause of vibration of a motor

摘要

A system (10) for determining the cause of a vibration of an engine that determines the cause of a vibration occurring in a connected state in which a motor (40) is directly or indirectly connected to a main shaft, and comprising: a vibration sensor unit (10); 12) suitable for detecting a vibration of the engine (40) in a driven state, wherein the vibration sensor unit (12) generates a second vibration, which is a vibration of the engine (40) in a stand-alone state before shipment, a second vibration in that a vibration of the motor (40) after shipping is in a stand-alone state and in an unconnected state in which the motor (40) is not connected to the main shaft (20), and detects a third vibration that is a vibration a vibration information storing unit (13) in the vibration sensor unit (12) information detected by the vibration sensor unit (12) s (40), the information including first vibration information, second vibration information, and third vibration information; anda source (14) for determining the cause of a vibration that determines the cause of a vibration occurring in the connected state on the basis of the first vibration information, the second vibration information, and the third vibration information stored in the unit for storing Vibration information (13) are stored.
