Summary
In short
- A motor current signature analysis is a record used in KnowMaintain that analyses motor current to find rotor bar, air gap and load faults without stopping the machine. It is built against ISO 55001 cl.8.1 and forms part of the Reliability and Predictive Maintenance programme.
- Run on the condition monitoring route. Completed by a trained analyst.
- The template holds 45 fields across 5 sections.
- Scoring is severity, where low is good.
- ISO 55001 is asset management systems. The international standard for getting value from physical assets across their whole life. Underpins the maintenance templates.
- It connects to the rest of the library: links Condition monitoring, Work orders.
What it is
What it is
What is a motor current signature analysis?
A motor current signature analysis is a record used in KnowMaintain that analyses motor current to find rotor bar, air gap and load faults without stopping the machine. It is built against ISO 55001 cl.8.1 and forms part of the Reliability and Predictive Maintenance programme.
When is a motor current signature analysis completed?
A motor current signature analysis is completed at the moment the event happens, rather than reconstructed afterwards. Run on the condition monitoring route.
When to use it
When to use it, and when not to
This record is one step in a larger programme. Using it for work that belongs to a neighbouring template produces records that are hard to report on later.
Use it for
- The event or activity this record covers has occurred, or is about to
- The workspace is being set up, or the register needs an entry added or retired
- You are running the Reliability and Predictive Maintenance programme and this is one of its steps
- A linked record needs this one to exist: links condition monitoring, work orders
Not for
- Alignment and Balance Record, which records shaft alignment or rotor balancing work, with before and after readings.
- Lubrication Route Record, which records the lubrication round, with what was applied where, how much, and any condition observed.
- Condition Monitoring Route Plan, which sets which assets are monitored, by which technique, at what interval and against which alarm limits.
- Anything outside KnowMaintain, which belongs in the workspace that owns that process

FAQ
Frequently asked questions
What is the motor current signature analysis template based on?+
It is built against ISO 55001 cl.8.1. ISO 55001 is asset management systems. The international standard for getting value from physical assets across their whole life. Underpins the maintenance templates. ISO is international Organization for Standardization. A voluntary international standard. Widely adopted, often required by customers, and certifiable where a management system standard.
What sections does the motor current signature analysis contain?+
There are 5 sections: header, conditions, findings, assessment, result. Together they hold 45 fields, 33 of which are required.
How many motor current signature analysis records should we have?+
This is a singleton. One record per workspace, set up once and maintained, rather than one per event. Other templates refer back to it.
Which programme does the motor current signature analysis belong to?+
It is part of Reliability and Predictive Maintenance. Intervals set by failure behaviour rather than by the calendar.
How is a motor current signature analysis scored?+
Scoring is severity. Low is good. Scores exist to make the form tell you something, not to produce a percentage for its own sake.
Can the motor current signature analysis template be changed?+
Yes. Every field, option, score and conditional rule is editable, and the links to other templates come with it. Most teams install it as it is, run it for a cycle, then adjust.
The agents
What the agents do with it
The form is the easy part. Keeping it current, routing it to the right owner and holding the evidence together is the work that actually slips.
Holds the motor current signature analysis library against your registers, routes each record to its owner, and keeps the evidence trail together.
Coordinates the crew, rolls completion and exceptions into one view, and holds every write for your approval before it touches a record.
This template lives in KnowMaintain — asset maintenance. Work orders, planned maintenance, calibration, reliability and shutdowns.
