Motor vibration cause determination system
First Claim
1. A motor vibration cause determination system that determines the cause of vibration occurring in a connection state in which a motor is directly or indirectly connected to a main shaft, comprising:
- a vibration sensor unit capable of detecting vibration of the motor in a driving state, the vibration sensor unit detecting a first vibration which is vibration of the motor in a stand-alone state before shipping, a second vibration which is vibration of the motor in a stand-alone state and in a non-connection state in which the motor is not connected to the main shaft after shipping, and a third vibration which is vibration of the motor in the connection state;
a vibration information storage unit that stores information on the vibration of the motor detected by the vibration sensor unit, the information including information on the first vibration, information on the second vibration, and information on the third vibration; and
a vibration cause determination unit that;
determines whether a cause of vibration, occurring in the connection state, originated in the connection state or the non-connection state, on the basis of the first vibration information, the second vibration information, and the third vibration information stored in the vibration information storage unit; and
determines the cause of the vibration occurring in the connection state on the basis of whether the cause of vibration originated in the connection state or the non-connection state.
