IEC recommends implementing a PM schedule for your slip rings at your worksite. This scheduled upkeep will help extend the intervals between refurbishment provided by IEC. The maintenance schedule will be tailored based on several factors, including RPMs, surrounding environment, total revolutions, and amperage.

​

Maintenance typically involves removing dust from the slip ring. However, this may vary depending on the specific model and customer application.  The document provided gives a basic guideline on scheduling and the procedure of PM. Please note this document only supports standard and oil-filled flange mount designs. Each application and design is different and will affect the intervals between when PM is necessary. 

 

Recognizing that each application is different, IEC is available to assist in curating a PM schedule fit for your needs.
