Windpower

MotorDoc LLC presents the EMPATH, ECMS-1, and ECMS line of data collectors and continuous monitoring Electrical Signature Analyzers (ESA) for on and off-shore wind turbine generator, transformer, and powertrain analysis. With two decades of windpower experience on all major platform types.

For information on how we detect wye ring fractures, go to Windpower Generation Rotor Wye Ring Detection with EMPATH – EmpathCMS for a six minute video. All of the detection is now automated in the software from transformer through generator, gearbox, main bearings and blade unbalance frequencies.

Data Collection and Analysis is simply this fast – at the end, conditions displayed (EMPATH Data Collector for this video)

All it requires is the collection of 48 seconds of voltage and current from the base of most towers then our AI reviews the condition of your complete system. Detection, identification, and trending is not load dependent – so long as the turbine is generating, we can see it all! On the very first set of data we detect and trend:

Loose connections and transformer issues
Control issues
Generator
- Bearings
- Unbalance
- Misalignment
- Stator wedges, loose or missing
- Stator coil and rotor coil movement
- Wye ring fractures (DFIG)
- Broken rotor bars (Induction)
- Rotor magnet defects (permanent magnet)
- Stator or rotor winding stresses and developing shorts
- Loose stator
- Deteriorating brush circuit collector ring or brush issues
Gearbox
- All gearbox bearings
- Gear deterioration and wear
- Gear mesh and fractures
- Planetary gear issues including unbalanced planetary gears
- Misalignment between main shaft and gearbox
Main Bearings
- Defects
- Lubrication issues
Blades
- Blade unbalance or misalignment

*All defects are trended for detection of remaining life and severity based upon the data you enter.
