How are induction motors tested in the factory?
Chapter 9: Motor Noise and Product Sound Chapter 10: Servomechanical Power-Electronic Motor Drives Electric Motor Handbook By James L.Kirtley, Jr. 4.4: Induction Motor Testing 4.4 Induction Motor Testing All induction motors are tested before shipment from the factory. This testing can be subdivided in two groups: Routine tests
What’s the best way to check an electric motor?
Adjust the needle to 0 if possible. Locate a ground screw (often a green, hex head type) or any metal part of the frame (scrape away paint if needed to make good contact with metal) and press a test probe to this spot and the other test probe to each of the motor leads, one at a time.
What kind of motor test is NEMA MG1?
Depending on the size of the motor, some or all of the following tests could constitute routine tests: NEMA MG1 includes the first three tests for all motors, and the fourth test for medium motors only. The purpose of a prototype test is to evaluate all the performance characteristics of the motor.
Where does a leakage test take place on a motor?
The leakage current through insulation, expressed as resistance, is displayed so it can be graphed. This test may take place on installed or on-the-reel cable, tools, appliances, transformers, power distribution subsystems, capacitors, motors and any type of electrical equipment or wiring.

What is the purpose of routine motor testing?
Routine tests. The primary purpose of the routine test is to insure freedom from electrical and mechanical defects, and to demonstrate by means of key tests the similarity of the motor to a “standard” motor of the same design.
