scope:

This part of ISO 13373 sets out guidelines for the specific procedures to be considered when carrying out vibration diagnostics of various types of electric motors. The four motor types covered by this part of ISO 13373 are squirrel-cage induction, wound-rotor induction, salient-pole, and DC motors. NOTE - The first two types are defined in ISO 20958. This part of ISO 13373 is intended to be used by condition monitoring practitioners, engineers and technicians and provides a practical step-by-step vibration-based approach to fault diagnosis. In addition it gives a number of examples for a range of machine and component types and their associated fault symptoms. The procedures presented in this part of ISO 13373 can, in some cases, be applied to other types of electrical machines, such as generators, but there can be other specific techniques associated with such machines that are not included in this part of ISO 13373.
