The motor assessment will allow us to have detailed information about the motor and would allow us to categorize the motor under 3 R – RETAIN – REFURBISH & REPLACE
Step 1 of Evaluation
Measurement of stator resistance: The measurement of resistance is very important under static condition (when the motor was not energized). This parameter allows the algorithm to calculate the stator copper loss.
We need to take 10 sets (each in three phases) of reading and draw mean value and multiply with factor constant 1.1.
