How to Spot a Counterfeit Siemens 1FK7 Servo Motor: Real vs Fake
In today’s global marketplace, counterfeit industrial parts are more common than many realize—and servo motors are no exception. For facilities using Siemens 1FK7 motors, installing a fake or low-quality refurb can lead to costly failures, machine damage, or even safety risks. At Delta Automation, we regularly inspect and repair motors that were unknowingly sourced from unreliable vendors. Here’s how to identify a counterfeit Siemens 1FK7 and what to do if you suspect one in your system.
Why Counterfeit 1FK7 Motors Are a Growing Problem
The Siemens 1FK7 series is widely used in precision applications like CNC machining, robotics, and packaging systems. Its popularity makes it a prime target for counterfeiters—especially online sellers offering deals that seem too good to be true.
Fake or poorly refurbished motors can contain:
- Mismatched or off-brand internal components
- Resprayed or forged nameplates
- Inconsistent winding resistance
- Substandard shaft or bearing alignment
Signs of a Counterfeit Siemens 1FK7 Motor
Be on the lookout for these red flags:
- Inconsistent labeling: Genuine Siemens labels are laser-etched or heat-stamped—never just stickers. Look for missing model suffixes or off-font serial numbers.
- Suspicious packaging: If the box lacks Siemens branding, serial traceability, or proper cushioning, proceed with caution.
- Unusual wear on a “new” motor: Scuffed shafts, stripped screws, or misaligned cooling fans may indicate reuse or tampering.
- Price far below market rate: Significant underpricing often signals non-OEM or counterfeit goods.
What to Do If You Suspect a Fake
If you’ve already installed the motor, keep an eye out for:
- Inconsistent performance
- High heat buildup
- Motor controller fault codes
- Vibration or excessive noise
Do not continue running a suspected counterfeit motor. Even if it temporarily works, internal components may fail under load—causing further damage downstream.
