Abstract
Needs of condition based maintenance (CBM) have been increasing in preventive maintenance service. CBM is a service for implementing the inspection and maintenance before the failure occurs.
CBM is a technique to detect a sign for the state of equipment with continuously monitoring, to inspect and maintain them before occurring serious trouble.
In this presentation, result of the investigation for equipment controlled by electromagnet is reported.
The feature of this method is as follows.
(a)Judge the sign from the change of coil current and terminal voltage.
(b)Monitor a state without adding any sensing device.
