A previously-broken motor will never run at the same efficiency, even if repaired, so testing can make sure that the motor retains its performance over the maximum value of its useful life. It is highly recommended that motor testing be done, as once an electric motor accrues damage it is often irreversible (known as “core damage”). Each test can apply to most AC and DC motors, but each method of testing is dependent on the construction and application of the motor being evaluated. Mechanical motor testing often includes evaluating a motor’s rotor for cracks and shorted laminations. Electrical motor testing evaluates static parameters such as insulation (the barriers between winding interconnections/winding to earth), wire damage, current leakage, and/or dynamic parameters such as balance, temperature rise, distortion, etc. Electric motors are highly integrated machines that can develop faults in many areas and, if left unattended, a damaged motor can result in dangerous working conditions. The main objective of motor testing is to assess the integrity of a motor and ultimately prevent the occurrence of unnecessary failure. Test equipment set-up for rotational balancing of motors and rotors. This article will go over the basics of motor testing and what types of motor testing are provided. There are many kinds of motor testing services, which can not only prevent failures but make sure the motor is working at its optimal level. Motor testing services are available to help ensure your motor is working correctly by testing certain standard parameters, which can reveal potential risks. Steps to prevent motor malfunctions should be given due consideration, especially when using a complex motor, as repairs can result in significant, costly delays and downtime.

Electric motors may or may not be expensive to purchase, but they are almost always more expensive to repair.
