How To Perform A Three Phase Motor Test (Physical And Electrical Tests)

When testing a three-phase motor, its mechanical and electrical conditions are evaluated. Many tests must be done to make sure the engine is checked thoroughly.In this tutorial, we have listed a variety of mechanical and electronic tests that can be performed on a motor. Always employ an electrically and mechanically competent individual to conduct tests.Photo Credited: PesqualityThe tests that will be examined are as follows:A physical check of the motorA physical examination of the motorTesting the incoming supplyEarth continuity and resistance testInsulation resistance testMotor winding resistance testMotor winding continuityFull load amp (FLA) test By carrying out these inspections, we can determine the general health of a three-phase electrical motor and locate any specific problems it may be experiencing. When a motor fails or needs to be checked, an electrician should perform the following tests.How to check out a three-phase motor physicallyWhen you test a three-phase motor, you should first look at how it looks. This will inspect the motor's shaft, cooling fan, and main body. When looking at a motor part with your eyes, the power should be separated and, if possible, unplugged from the power source.It would be best if you tried to turn the motor while it was disconnected. If this is simple, the motor bearings are in good shape. If the motor is hard to turn, it means there is a mechanical problem. The shaft or directions may have broken.Another check is to look at the motor's body, shaft, and cooling fan to see how they look. First, inspect the motor's external body for evidence of cracking, corrosion, or damage.The condition of the motor's shaft is the next thing to examine; this is easier to do when the motor is detached from the coupling or mechanical component to which it is connected. Ensure the shaft is in good shape, with no signs of wear, cracking, or damage.The final visual inspection should focus on the cooling fan and cooling fan housing. To check out the cooling fan, you must take off the housing, which is usually held together by a few screws. You should check that the fan's blades are free of fractures and rust. Check the cooling fan casing for cracks, corrosion, or visible damage.
