Which tests are worthwhile

If you're going to the trouble to hook up a motor tester, Baker, PdMA or whatever, why not just run all the tests it's capable of and not worry about it, only takes a few minutes?  I also put a note on the motor to be informed where it is used in the future so I can use the test as a baseline.

I totally agree with the statement above.  You need to check resistance, insulation, windings as well as any other factors your tester will give you information on. The more the merrier.  And absolutely tag each motor with the results.  Additionally keep a copy of the results in a secure place as tags do get destroyed and rendered illegible.  You might find the linked case study helpful.http://cstsolutionsllc.com/wp-...agner-Case-Study.pdf

As stated by others, depends on what type of equipment you are using or plan to use. Resistance phase to phase and each phase to ground, capacitance to ground, inductive imbalance are all good tests on electric motors.
