Servo motor encoder replacement
When an encoder cannot be repaired, we fit a matching replacement and make the motor behave exactly as before: same interface, resolution and mechanical fit, aligned to the rotor and, where needed, programmed with the motor's data. You get the motor back tested, not a loose encoder and an alignment problem.
Repair turnaround you can plan around
Send a photo of the nameplate first. We confirm whether the motor is repairable, and the quote, the same working day.
Urgent: 3 working days
Repair, encoder alignment and test, counted from the day the motor reaches the bench and the quote is approved.
Standard: 7 working days
Full repair, encoder alignment, run test under load and a printed test report.
- Free repairability check from a nameplate photo
- Printed test report with every motor
- Written warranty, terms stated on every quotation
- Pickup can be arranged; parts that must be imported are quoted with their own timeline
01Matching
What has to match
| Item | Why it matters |
|---|---|
| Interface | Incremental, Hiperface, EnDat, Fanuc, Mitsubishi, Tamagawa, Yaskawa and SSI encoders talk to drives in different ways |
| Resolution | Counts per revolution must match the drive parameter, for example 2,048, 8,192, 131,072 or 1,048,576 |
| Commutation pattern | UVW, C1 to C8, sine and cosine tracks or memory offset, to suit the motor's pole count |
| Single or multi-turn | Multi-turn absolute encoders keep the revolution count and need a battery or a geared multi-turn stage |
| Mechanical fit | Tapered or hollow shaft, mounting, connector and cable exit |
| Memory format | Motors that store data in the encoder need that data written back |
02Process
How a replacement is done
Identify
Read the label and memory.
Source
Exact or approved match.
Fit
Mount without stressing bearings.
Align and program
Offset and motor data.
Prove
Run test and report.
03FAQ
Questions
Can I buy just the encoder from you?
Yes, where we can source the exact type. We recommend sending the motor so the encoder is aligned and programmed; a bare encoder fitted without alignment usually causes overcurrent or rough running.
Will a compatible encoder from another maker work?
Only if the interface, resolution, commutation pattern and memory format match what the drive expects. We check this before offering an alternative and tell you plainly if there is none.
How long does a replacement take?
From stock or Indian sources, within the urgent or standard timelines. Imported encoders are quoted with their own lead time.
Do you replace the encoder on obsolete motors?
Often, yes. Older incremental, Yaskawa C-channel and early serial encoders can still be sourced new, refurbished or as compatible types.

Send the nameplate or encoder label
A clear photo of the motor nameplate and, if the cover is off, the encoder label is enough to start. We reply with whether it can be repaired and a quote.
