This alphabetical overview lists ten industrial Servo manufacturers for buyers to investigate. Published by KEVOR, it uses the manufacturers’ official websites and is not a performance ranking. Confirm the offered model’s specifications, warranty and service terms directly with each supplier.
How this shortlist was prepared
The list focuses on manufacturers with relevant industrial Servo or motor-driven voltage-regulation products on their official websites. It does not mix household-only AC stabilizer brands into an industrial Servo ranking.
Information was checked on 18 October 2026. Product ranges and company details may change. Inclusion is not an endorsement, independent product test, customer rating or claim that a supplier fits every installation. Official source links are listed below.

Compare the same electrical requirement
Send every shortlisted supplier the same machine nameplate, operating load, starting-demand information and measured minimum/maximum voltage. Different input windows, cooling, protection or service scope can produce different prices. Compare the configuration before the headline amount.
| Comparison point | What to ask for |
|---|---|
| Capacity and load | Rated KVA, current and load capability across the complete stated input range. |
| Phase regulation | Supply wiring, phase correction arrangement and permissible imbalance. |
| Performance | Output tolerance, correction speed, response definition and supporting test conditions. |
| Construction | Cooling, winding/construction details where claimed, enclosure, dimensions and weight. |
| Protection and bypass | Exactly what is supplied as standard and what is optional. |
| Commercial terms | GST, packing, freight, delivery, installation, payment and warranty scope. |
| Service | How a fault is reported and how support is arranged at the installation location. |
Discuss a KEVOR requirement
KEVOR is the publisher of this guide. Its own offer is presented separately from the ten-company shortlist: single-phase Servo 1–60 KVA, three-phase Servo 10–100 KVA and custom-made rolling-contact / linear requirements. KEVOR INDIA supplies servo voltage stabilizers for industrial and commercial loads.
Share the machine nameplate and site-voltage details for a technical quotation. Pan-India door delivery is available; freight, installation and warranty arrangements are confirmed for the order.
