Cables and connectors
Damaged motor and feedback cables, loose connectors and poor shield termination.
Advisory
Repeat-failure analysis for servo motors, drives and boards
When the same servo motor, drive, encoder or board fails again, replacing it again does not remove the cause. Star Automations reviews your failure history and the failed units and gives you a written finding of the likely cause and what to change. Star Automations is an independent multi-brand repair company and is not an OEM service centre.
01Causes
Where repeat failures usually come from
A unit that fails twice in the same place is usually being damaged by something around it.
Heat and ventilation
Blocked fans, dusty panels and drives running hot for long periods.
Power quality and earthing
Supply dips, noise and earthing problems that stress drive and board components.
Mechanical load and bearings
Misalignment, overload and bearing wear that pull the motor and drive down together.
Feedback and encoder faults
Encoder faults that look like drive or motor faults, and the reverse.
Parameters and set-up
Settings that push a unit beyond what the machine needs.
02Input
What you send
Start with what you have. More detail makes the finding more specific.
- List of failed units with make, model and dates of failure
- Fault codes and what the machine was doing at the time
- Machine, duty and environment notes, with photos of the panel
- The failed units themselves, where they are available
03Output
What you get
A written analysis with the reasoning shown.
- The failure pattern across your units, grouped by cause
- Likely cause for each group, with the bench evidence behind it
- Changes recommended at the machine, panel or cable level
- Units at risk of repeating, and spares worth holding
04Process
How the analysis runs
Findings come before any repair or purchase.
Send the history
Failure list, fault codes and photos, in a sheet or on WhatsApp.
Group the failures
Failures are grouped by unit type, machine and symptom.
Check the units
Failed units are checked at the bench where they are available.
Written findings
The likely cause per group and what to change.
Review call
We go through the findings with your maintenance team.
Do you need the failed units?
The history alone gives a partial view. With the units, the bench findings show which part failed and what damaged it.
Is this only for units Star Automations repaired?
No. Any make can be reviewed.
Can the machine be reviewed on site?
Where the cause sits at the machine or panel, an on-site review can be arranged. Say so when you send the list.
Will the analysis tell me exactly why a unit failed?
It gives the likely cause with the evidence found. Where the evidence is not enough, the findings say so and list what to record next time.
