AC Drive and VFD Supplier in Ahmedabad: Buying Guide

Key Takeaways

We supply Schneider Electric Altivar and Frecon AC drives (VFDs) from Ahmedabad.
Size a VFD by motor current and load type, not only by kW.
Pumps and fans save energy with a VFD; conveyors and extruders gain soft start and speed control.
Panel ventilation, cable length and dust matter as much as the drive model in Ahmedabad's industrial estates.

Pumps, fans, blowers, conveyors, mixers and extruders run in every industrial estate around Ahmedabad, and many of them still run at full speed with a valve or damper doing the control. An AC drive changes that. As an AC drive and VFD supplier in Ahmedabad, RB Automation supplies Schneider Electric Altivar and Frecon drives and helps you size them for the motor and the load.

What an AC Drive (VFD) Does

An AC drive, or variable frequency drive, controls the speed of an AC induction motor by changing the frequency and voltage it receives. That gives a soft start, adjustable speed, controlled stopping and built-in motor protection. On pumps and fans, running slower instead of throttling usually cuts energy use, because their power demand falls sharply as speed drops.

AC Drives We Supply in Ahmedabad

Schneider Electric Altivar

As an authorised Schneider Electric partner we supply the Altivar low voltage AC drive and Altivar general purpose AC drive ranges, a common choice where plants standardise on Schneider PLCs and panels. See the Schneider AC drive page.

Frecon

We supply the Frecon FR01 smart inverter, FR150A, FR500A, low power AC drives for machines, pumps and general industrial duty, plus the FR150T/FR500T solar (PV) water pump inverter. See the Frecon AC drive page.

How to Size and Select a VFD

Motor nameplate: rated current, voltage and power. Size by current first.
Load type: variable torque (pumps, fans) or constant torque (conveyors, extruders, mixers). Constant torque and frequent starts need more overload capacity.
Supply: single-phase or three-phase input, and the voltage at the panel.
Control: keypad, analogue signal, digital inputs or communication with a PLC.
Braking: high-inertia loads that must stop quickly may need a braking resistor.
Environment: panel temperature, dust and cable length to the motor.

VFD Applications in Ahmedabad

Process plants in Naroda and Vatva: pumps, agitators, cooling tower fans and blowers.

Textile units across the city: fans, humidification plants and winding or processing machines that need steady speed.

Engineering and auto plants at Sanand, Changodar and Santej: conveyors, compressors and machine spindles.

Buildings and utilities: water supply pumps and HVAC fans.

Installation and Care

Most VFD failures come from heat, dust and loose connections, not from the drive itself. Keep panel ventilation clear, clean filters and heat sinks, tighten terminals and keep parameter backups. Our low voltage AC drive maintenance checklist covers this step by step.

AC Drives We Supply Compared

Range	Brand	Typical use
Altivar low voltage AC drive	Schneider Electric	Plants standardised on Schneider PLCs and panels
Altivar general purpose AC drive	Schneider Electric	Pumps, fans, conveyors, general machines
FR01 smart inverter	Frecon	Compact machine and general duty
FR150A	Frecon	Compact general purpose duty
FR500A	Frecon	General industrial duty
FR150T / FR500T	Frecon	Solar (PV) water pump inverter for pumping systems
Low power AC drives	Frecon	Small motors on machines

Power ratings and supply options differ by series; see each product page or send us the motor nameplate.

Variable Torque vs Constant Torque Loads

Load type	Examples	What it means for the drive
Variable torque	Centrifugal pumps, fans, blowers	Torque falls with speed; the biggest energy savings
Constant torque	Conveyors, extruders, mixers, positive displacement pumps	Needs full torque at low speed and more overload capacity

A Typical VFD Application in Ahmedabad

A typical case in a Naroda process unit: a cooling tower fan runs at full speed all year, and the outlet water temperature is controlled by switching the fan on and off. Adding an AC drive and a temperature signal lets the fan run only as fast as needed, which reduces power use in cooler months, removes the starting current surge and reduces wear on the belts and gearbox. The same approach applies to transfer pumps that today run against a partly closed valve.

Common VFD Mistakes to Avoid

Sizing by kW only and ignoring motor current and load type.
Poor panel ventilation, the most common cause of trips and failures.
Long unshielded motor cables without considering output filters.
Stopping high-inertia loads quickly without a braking resistor.
No backup of drive parameters.

What to Send for an AC Drive Quote

Why Choose RB Automation

We supply two drive brands, so we can recommend Schneider where a plant standardises on it and Frecon where it fits the application and budget. We also supply the PLCs, HMIs and sensors around the drive. See our PLC guide for Ahmedabad or the full automation range we supply in Ahmedabad.

Conclusion

A correctly sized AC drive saves energy, protects the motor and gives you control of the process. Send your motor nameplate and load details to RB Automation in Ahmedabad for a Schneider or Frecon recommendation.

Frequently Asked Questions

Which AC drives do you supply in Ahmedabad?

We supply Schneider Electric Altivar low voltage and general purpose AC drives, and Frecon FR01, FR150A, FR500A, FR150T/FR500T and low power AC drives.

Is an AC drive the same as a VFD?

Yes. AC drive, VFD (variable frequency drive) and inverter are common names for the same device, which controls the speed of an AC motor by changing frequency and voltage.

How do I size a VFD for my motor?

Size the drive by the motor's rated current and voltage, then check the load type. Constant torque loads and frequent starts need more overload capacity than pumps and fans. Send us the motor nameplate to confirm.

Can a VFD save energy on pumps and fans?

Usually yes. Running a pump or fan slower instead of throttling it with a valve or damper reduces power demand, because their power falls sharply as speed drops.

What is the price of a VFD in Ahmedabad?

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.
