Performing tests on an electric motor is no easy task. You have to be careful about what voltage to use, what parameters are correct for the type of motor, and what specifications the test needs to be performed according to. And there are certain electric motor test instruments that are used to gather key data to evaluate the condition of a motor. Even if you're not the one performing the tests, it's still a good idea to have an idea of what those tests are and what test instruments are involved.
These tests are referred to as "standard" however, there are many opinions out there on voltage levels, what tests can be used when, etc. Watch the video to learn more.
