Vibration diagnostics for industrial equipment and wind turbines
Assessing rotating and vibration-critical equipment from vibration spectra — for industry and wind power. Deep hands-on experience with wind turbines.
Vibration diagnostics is an instrumental analysis method used to assess the condition of industrial machinery from vibration spectra: detect hidden defects, estimate remaining life, and recommend repair or replacement — often without full disassembly.
EcoTEK provides vibration diagnostics for industrial and energy facilities. Our core expertise is wind turbines (WTGs): see Key focus: wind turbines below; typical industrial assets are also listed, with turbine subsystems described in detail.
1. What is vibration diagnostics
It covers measurement, processing, and analysis of vibration signals from rotating elements (gearboxes, motors, pumps, compressors, etc.). The method estimates machine condition without disassembly; in many cases measurements are taken while the equipment is running.
From accelerometer data, specialists detect bearing defects, gear mesh issues, imbalance, and misalignment, and provide recommendations for repair and maintenance.
EcoTEK specialists use professional hardware and software from leading vendors; for wind turbines we bring deep experience inspecting nacelles, gearboxes, and generators under real operating conditions.
Key focus — wind energy (WTGs)
We perform vibration diagnostics for any industrial rotating equipment where regulations or condition require it. At the same time, EcoTEK’s deepest practical expertise is concentrated on wind turbines — the core of our portfolio: construction, O&M, and WTG repair across Belarus, Russia, and Kazakhstan.
#1
Highly loaded subsystems. Multiplier gearboxes, generators, main bearings, and the rotor are typical risk areas; similar defect classes exist on ground-based equipment, but on a turbine the cost of a diagnostic error is higher due to height, downtime, and component value.
#2
Full lifecycle with one contractor. Knowledge of WTG design, operating modes, and OEM requirements complements pure vibration methodology: the customer receives not only spectra but actionable conclusions for operations and repair.
#3
Online and portable surveys. We configure and analyse continuous monitoring on turbines and carry out periodic walk-around surveys with portable analysers — including under O&M contracts and for incident investigations.
2. Assets we diagnose
Typical targets are rotating equipment with bearings, gears, and shafts; on wind turbines the most heavily loaded nacelle components are prioritised.
Industrial and power plant equipment
Vibration diagnostics applies to pumps and compressors, fans, motors and generators (including large turbogenerators), gearboxes and multipliers, process trains where vibration and rotor dynamics are critical. The goal is to detect wear, loosening, misalignment, and developing faults before failure.
Wind turbines (WTGs)
On a wind turbine, vibration control focuses on critical subsystems; below are the main inspection targets.
#1
Main bearing — one of the most heavily loaded components. It carries large variable loads from the rotor. Typical defects include spalling of raceways and wear of rolling elements.
#2
Gearbox (multiplier) — a complex gear train that steps up low rotor speed to generator speed. We diagnose tooth wear, imbalance, shaft alignment, and bearing defects.
#3
Generator — bearings (drive and non-drive end) and electrical faults (e.g. rotor winding damage) that also show in the vibration signature.
#4
Yaw system — the ring gear that yaws the nacelle into the wind is monitored.
#5
Rotor (blades and hub) — rotor imbalance affecting overall WTG vibration.
3. How vibration diagnostics is performed
For industrial assets and wind turbines we use two main approaches; on WTGs, online monitoring and periodic walk-around surveys with a portable analyser are especially common.
Online (continuous) monitoring
Critical components (at the factory or on the turbine) are fitted with vibration sensors (accelerometers). Data are streamed in real time to a condition monitoring system. The system processes signals and alarms when limits are exceeded.
EcoTEK specialists can perform technical analysis of your existing monitoring system or help design measurements on critical components. Using dedicated software, vibration levels are tracked in real time; on critical events the customer is notified and the turbine is inspected.
This is the most advanced approach to track defect progression and estimate remaining component life.
Periodic inspection
- A specialist with a portable analyser visits the site; on a WTG they climb into the nacelle and place sensors at defined points (gearbox and generator bearings, main bearing). On industrial equipment, measuring points follow an agreed scheme and safe access.
- Data are acquired under different operating conditions (ramp-up, rated power, typical operating modes).
- Data are analysed on a PC with specialised software (spectral and time-domain analysis).
4. Benefits of regular diagnostics
For industry and wind power, regular diagnostics address similar goals: fewer unplanned stops and condition-based repair. On a turbine, gearbox or generator failure is especially costly:
Preventing catastrophic failures. Gearbox or generator destruction is among the worst outcomes. Vibration monitoring helps catch developing faults early, when they can still be addressed with planned repair.
Lower maintenance costs. Moving from time-based maintenance to condition-based maintenance — servicing only assets that actually need work.
Higher availability and energy yield. Fewer unplanned outages directly improve project economics.

FAQ — vibration diagnostics
It is instrumental analysis of vibration from bearings, gearboxes, rotors, and other components to assess condition without full disassembly. On wind turbines, typical targets include the main bearing, gearbox, generator, yaw system, and rotor. EcoTEK performs measurements and interpretation according to industry practice and customer requirements.
Main objects: main bearing, gearbox (multiplier), generator, yaw system, rotor (blades and hub). We monitor bearing wear, imbalance, shaft alignment, and gear tooth defects.
Online monitoring uses continuous sensors on critical WTG components with real-time data streaming to an analysis system — ideal for tracking defect evolution.
Periodic inspection is a site visit with a portable analyser at defined measurement points, often within planned maintenance.
For industrial assets, frequency follows plant procedures, standards, or OEM guidance (often at least annual for critical trains). For WTGs it follows manufacturer requirements and operating mode; with online monitoring, signals are tracked continuously, 24/7.
Measurements are often taken on running equipment to capture spectra at operating conditions. A shutdown may be needed for safe sensor placement or access. Conditions are agreed when planning the visit.
Accelerometers, portable analysers, and specialised software for spectral analysis. EcoTEK uses professional equipment and software from leading manufacturers.
On a WTG, measurements are taken in the nacelle at height, with access to gearbox and generator, safety constraints, and typical turbine operating modes (ramp-up, rated power). Spectral methods are similar to industrial gear trains, but measurement context and access are turbine-specific — where wind farm experience matters.
