Key Takeaways
- Looms, texturising and dyeing machines, pumps and blowers are the main VFD loads in Surat's textile belt.
- We supply Schneider Electric Altivar and Frecon AC drives to Surat from our Ahmedabad base.
- Size the drive on motor current and load type; constant torque and frequent starts need more overload capacity.
- Lint, humidity and heat in textile sheds make panel ventilation and filter cleaning as important as the drive model.
Few cities run as many motors per square kilometre as Surat. Weaving sheds in Sachin, Palsana and Kim hold rows of looms, texturising units run long machines with several motors each, and processing houses keep dyeing machines, pumps, blowers and stenter fans turning around the clock. Speed control on these motors affects both product quality and the power bill. RB Automation is an AC drive and VFD supplier in Surat, offering Schneider Electric Altivar and Frecon drives with sizing support from Ahmedabad by phone, WhatsApp and email.
What a VFD Changes on a Motor
A variable frequency drive feeds an AC induction motor with adjustable frequency and voltage. The motor can then start gently, run at any set speed, stop under control and be protected against overload and phase faults. On centrifugal pumps and fans, lowering speed instead of throttling with a valve or damper usually saves a large share of the energy, because their power demand falls steeply with speed.
Drive Ranges We Supply to Surat
Schneider Electric Altivar
Processing houses that already run Schneider panels often want their drives to match. As an authorised Schneider Electric partner, RB Automation offers two Altivar lines: the low voltage series and the general purpose series. Both are summarised on our Schneider AC drive page.
Frecon
Where budget and application point that way, Frecon is the alternative. Small machine motors suit the low power range or the compact FR01 smart inverter; general machine and pump duty suits the FR150A and FR500A; and the FR150T/FR500T is a solar (PV) water pump inverter for pumping systems. The Frecon AC drive page lists them all.
Typical VFD Loads in Surat
Weaving and texturising
Looms, warping and sizing machines, and texturising and twisting machines need steady, adjustable speed and gentle starts that protect yarn and mechanics. Several motors on one texturising machine may need to hold a fixed speed ratio.
Dyeing and processing in Sachin, Pandesara and Kadodara
Circulation pumps on dyeing machines, stenter and dryer fans, washing ranges and boiler feed pumps all benefit from speed control, both for process consistency and power savings.
Chemical and heavy plants at Sachin, Ichhapore and Hazira
Agitators, transfer pumps, cooling tower fans, blowers and conveyors.
Effluent treatment
Aeration blowers and transfer pumps in treatment plants run long hours, which makes them strong candidates for a VFD.
Sizing a VFD Correctly
- Read the nameplate: rated current and voltage first, kW second.
- Classify the load: pumps and fans are variable torque; looms, conveyors, agitators and positive displacement pumps are constant torque and need more overload margin.
- Count the starts: machines that start and stop often need a drive rated for it.
- Check the supply: single-phase or three-phase input and the voltage at the panel.
- Decide the control: keypad, potentiometer or analogue signal, digital inputs, or communication with a PLC.
- Consider braking: a loaded beam or drum brought to rest fast pushes energy back, which a braking resistor can absorb.
Keeping Drives Healthy in Textile Sheds
Cotton and polyester fluff, humidification and summer heat are hard on electronics. Most drive trips in textile units trace back to blocked heat sinks, clogged panel filters and loose terminals rather than a faulty drive. Clean filters on a schedule, keep panel fans working, re-tighten power terminals and save a copy of the parameters. Our low voltage AC drive maintenance checklist sets out a routine.
Picking a Drive Range for a Surat Load
| Load in Surat | Range to start from | Maker |
|---|---|---|
| Processing house already on Schneider panels | Altivar low voltage | Schneider Electric |
| Effluent blowers, transfer pumps, conveyors | Altivar general purpose, or Frecon FR150A / FR500A | Schneider Electric or Frecon |
| Small motors on winders and texturising machines | Frecon FR01 or low power range | Frecon |
| Solar (PV) water pumping | Frecon FR150T / FR500T | Frecon |
Each series has its own power and supply limits, listed on its product page; a nameplate photo lets us confirm the fit.
Textile and Process Loads Compared
| Load | Torque behaviour | What the drive needs |
|---|---|---|
| Dyeing machine circulation pump, stenter fan, ETP blower | Variable torque | Standard rating; largest energy savings |
| Loom, warping and sizing drives, conveyors | Constant torque | Full torque at low speed, overload margin |
| Agitators and positive displacement pumps | Constant torque | Overload margin, sometimes a braking resistor |
A Typical VFD Application in Surat
Think of a typical stenter in a Sachin processing house. Its hot-air circulation fans run at full speed whatever the fabric, and air flow is trimmed with dampers. Fitting AC drives to the fan motors lets the operator set fan speed for each fabric quality, which helps drying consistency and cuts power use when full air flow is not needed. The same unit's dyeing machine circulation pumps and the effluent plant's aeration blowers are good next candidates, because they also run long hours on centrifugal loads.
Where VFD Projects Go Wrong
- Matching the drive to the kW figure while overlooking full-load current and the type of load.
- Letting fluff block panel filters and drive heat sinks.
- Long, unshielded motor cables with no thought to output filters.
- Stopping heavy rolls or drums quickly without a braking resistor.
- Never saving the drive's parameters, so a replacement takes hours to set up.
What Helps Us Quote a VFD
- A nameplate photo showing kW, amps and volts
- What the motor drives, and how often it starts
- Single-phase or three-phase supply
- How speed will be set: keypad, analogue, digital inputs or PLC link
- Brand preference (Schneider or Frecon) and quantity
Why Choose RB Automation for VFDs in Surat
Offering both Altivar and Frecon means the recommendation follows your plant, not a single catalogue, and the PLC, operator screen and transmitters wired to the drive can come in the same order. Sizing is handled from Ahmedabad by phone, WhatsApp and email, with orders dispatched to Surat. See our PLC guide for Surat or the full industrial automation supplier in Surat page.
Conclusion
A well-sized drive gives Surat's looms, dyeing machines, pumps and blowers soft starts, steady speed and lower energy use. Send RB Automation the motor nameplate and a short description of the load and we will recommend a Schneider or Frecon drive.

Frequently Asked Questions
Which AC drives do you supply in Surat?
Schneider Electric Altivar low voltage and general purpose AC drives, and Frecon FR01, FR150A, FR500A, FR150T/FR500T and low power AC drives.
Can a VFD be used on a loom or texturising machine?
Yes. A VFD gives a soft start and adjustable, steady speed on looms, warping, sizing and texturising machines. These are usually constant torque loads, so the drive must be sized with enough overload capacity. Share the motor nameplate and machine type to confirm.
Will a VFD reduce power use on dyeing machine pumps and blowers?
Usually yes. Running a centrifugal pump or blower slower instead of throttling it reduces power demand, because their power falls sharply as speed drops.
Why do VFDs trip often in textile units?
The most common causes are fluff blocking heat sinks and panel filters, high panel temperature and loose terminals. Regular cleaning, working panel fans and tight connections prevent most trips.
What is the price of a VFD in Surat?
There is no fixed price list. The price depends on the brand, power rating, supply, options and quantity. Use the form on this page, call +91 8511104864 or email contact@rbautomate.com for a quotation.
