Why your machines should run like clockwork: The power of Machine Fault Analysis
Published on August 21, 20261. Introduction: The ORBITS philosophy
In a modern production environment, reliability is no coincidence; it is the direct result of deep insight. At ORBITS, we hold an unwavering vision: Machines should work like clockwork — machines must run like clockwork. When a crucial part of the driveline fails, simply collecting data is not enough. We go further: We forge insights. The core of our philosophy is a multidisciplinary approach that analyzes the entire chain of electrically coupled rotating machinery. Where separate analyses often focus on a single domain, ORBITS offers significant added value by mapping the direct correlation between the electrical power supply, the Variable Frequency Drive (VFD), the electromagnetic field of the motor, and the mechanical load. We forge insights by understanding how a power quality issue in the supply translates into mechanical stress in a bearing. Without this comprehensive understanding of the interactions across the entire driveline, the true dynamics remain invisible and the solution pure guesswork. In a world of complex assets, mere data extraction is insufficient; only by understanding the "root forces" do we transform data into strategic value.
2. The problem: symptom vs. root cause
When a machine fails, operational pressure is often huge. The immediate reaction of many organizations is understandable: the machine must get back up and running as quickly as possible. However, this leads to a dangerous "trial-and-error" culture where quick fixes are applied to symptoms without addressing the root cause. At ORBITS, we see this as a direct threat to the maintenance budget and consequently Total Cost of Ownership (TCO) and Return On Investment (ROI). Repairing without understanding undermines a maintenance manager's strategic goals. It leads to unnecessary expenditures (replacing components that are not the cause) and erodes the credibility of the engineering team. The risks of this approach are evident:
Recurring problems and chronic unreliability: The failure inevitably returns because the underlying forces remain unaddressed.
Components fail to reach their theoretical lifespan: New components degrade prematurely due to uncorrected system fault
Escalating maintenance costs and unplanned downtime: The vicious cycle of reactive repairs drives OPEX expenses to unsustainable levels.
Loss of crucial evidence: Overly hasty repairs and clearing error codes erase the information required for a definitive diagnosis.
To break this cycle, a scientific methodology is essential—one that looks beyond the failed part and uncovers the forces behind the failure.
3. The solution: The science behind Machine Fault Analysis (MFA)
-
Step 1 Context
Context and symptom analysis
Every failure tells a story. We don't start with measuring; we start by listening. By mapping out the machine's history, load profiles, and fault records, we build a targeted hypothesis. This contextual depth ensures that subsequent measurements are extremely focused.
-
Step 2 Measuring
Advanced measurements
Importance of cross-domain dataForces only become visible when the right signals are measured in relation to one another. We leverage cross-domain data. Here, we analyze the interaction between VFD parameters, the electromagnetic flux of the motor, and the mechanical vibrations of the load. It is the correlation across these domains that reveals the invisible interactions in the driveline.

Step 3: Root cause
Fault verification and root cause
In this phase, we filter out the noise and look for patterns that confirm or refute the hypothesis. Within MFA, our independence and in-house developed methods allow us to objectively test each hypothesis, minimizing bias and providing clear evidence, even for complex phenomena such as winding degradation, bearing currents, excessive clearance, a cocked bearing, or a broken tooth in a gearbox.

Step 4 Plan
Reliability Action Plan
Insight is worthless without targeted action. Our Reliability Action Plan categorizes measures based on their location in the driveline (supply, motor electric, motor mechanic, load) and their risk profile (severity vs. occurrence). We provide not just repair advice, but a strategy to prevent recurrence in both the short and long term.
Strategic takeaway: MFA is a valuable investment that restores the machine to a healthy operational state and effectively reduces the risk of future failures. Engaging ORBITS early prevents recovery actions from clouding the truth and allows you to permanently safeguard reliability.
4. The bigger picture: Integration into the ORBITS ecosystem
While MFA is often deployed during acute problems, it serves as the stepping stone to a proactive asset management policy. ORBITS offers an ecosystem of services that guarantee reliability throughout the entire lifecycle. A crucial aspect here is our independence: our services are our only product, ensuring that every recommendation serves only one purpose: improving the reliability of your assets.
-
Machine Fault Analysis
The scientific approach to solve acute problems with advanced diagnosis.
-
Machine Health Scan
A proactive screening to detect abnormal conditions before degradation occurs.
-
Reliability Impact Analysis
An in-depth audit testing whether your maintenance plan, organization, and spare parts inventory are optimally aligned with the actual risk profile of your assets.
-
Insight as a Service
Utilizes the "Harvey" system, decoupling measurement time from expertise time. This is the ideal solution for remote or hard-to-reach assets, where data is collected locally and translated into action by our remote experts.
-
Training
We secure knowledge within your organization so your team learns to speak the language of the machine and recognize failure mechanisms faster.
Together, these services form a shield against unexpected downtime, restoring peace to your operations by replacing uncertainty with control.
5. Conclusion: Certainty over guesswork
Understanding the forces behind a symptom is the only path to strong decision-making and long-term value. Scientifically backed certainty forms the foundation for a healthy operation and optimal budget management. When you choose Machine Fault Analysis, you choose a definitive solution over a temporary fix. Facing recurring breakdowns or doubting the stability of your critical drivelines? Don't wait until the next intervention erases the evidence. Contact our experts at ORBITS today for an independent and clear diagnosis. Gain decisive insight before the next failure occurs.
