Motor analysis

Our team has the possibility to detect a variety of electrical and mechanical faults on induction motors through analysis of current, electromagnetic flux, temperature and vibration.

Based on statistical data compiled by the Electric Power Research Institute (EPRI), 47% of motor failures are due to electrical faults/failures. The 47% can be further broken down into rotor problems (10%) and winding problems (37%). Mechanical faults may sometimes have root causes that are electrical in nature.

Winding defects can occur due to insulation age, contamination, power surges, thermal overload, damaged wire/materials, vibration, and other causes. They begin as energy crossing an insulation fault (such as moisture or contamination), which isolates at least one turn. This generates additional stress and heat across the defect, which progresses until an arc is drawn and the winding fails.

Our team uses Alltest equipment to find such defects. Click here to find out more about this device.
