Are you properly testing your motors?
The importance of motor insulation testing should not be pushed aside or neglected. Making sure the insulation around the motor is still working efficiently is just as important as checking motors and testing their performance. This insulation is susceptible to dirt, moisture, temperature, vapors, oil, and aging. However, if the insulation is not kept in good condition, it can cause motor failures, which is much more costly and damaging, then simply testing and taking care of the insulation itself.
