ISO-13373-9 › Condition monitoring and diagnostics of machines - Vibration condition monitoring - Part 9: Diagnostic techniques for electric motors
The following bibliographic material is provided to assist you with your purchasing decision:
ISO 13373-9 specifies procedures to be considered when carrying out vibration diagnostics of various types of electric motors. The four motor types covered by ISO 13373-9 are squirrel-cage induction, wound-rotor induction, salient-pole and DC motors.
NOTE The first two types are defined in ISO 20958.
ISO 13373-9 is mostly applicable to motors with power above 15 kW.
ISO 13373-9 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 ISO 13373-9 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 ISO 13373-9.
The use of non-vibration quantities, such as voltage and current, to identify and analyse vibration-related faults in electric motors is outside the scope of ISO 13373-9.
