Systems, methods, and apparatus for rub detection in a machine

摘要

Systems, methods and apparatus for monitoring rub detection in a machine are provided. An alternating current voltage signal may be transmitted or communicated to at least one component of the machine. The transmitted signal may be monitored in the at least one component and at least one characteristic associated with the monitored signal may be compared to an expected value for the at least one characteristic. Based at least in part on the comparison, a rub condition or potential rub condition may be identified between the at least one component and another component of the machine.
