AC Drive and VFD Supplier in Delhi NCR: Buying Guide

Key Takeaways

NCR plants use VFDs on extruders, conveyors, pumps, fans and compressors.
We supply Schneider Electric Altivar and Frecon AC drives to Delhi NCR from Ahmedabad.
Size the drive by motor current and load type; constant torque loads such as extruders need more overload margin.
Hot summers and dust make panel ventilation and filter cleaning part of every VFD installation in the region.

Plastic extruders in Bawana and Narela, conveyors on auto component lines in Manesar, chilled water pumps in Noida's electronics plants and compressors in Faridabad's engineering units all have one thing in common: an induction motor that benefits from speed control. RB Automation is an AC drive and VFD supplier in Delhi NCR, supplying Schneider Electric Altivar and Frecon drives from Ahmedabad and helping buyers size them correctly.

What a VFD Does for a Motor

A variable frequency drive feeds the motor with adjustable frequency and voltage, so its speed can be set to what the process needs. It ramps the motor up gently, controls stopping and protects against overload, phase loss and over-voltage. On centrifugal pumps and fans the energy effect is large, since the power they draw drops steeply when speed is reduced.

AC Drive Ranges We Supply to Delhi NCR

Schneider Electric Altivar

We are an authorised Schneider Electric partner and supply the Altivar low voltage AC drive and Altivar general purpose AC drive ranges, along with the ATV12, ATV310 and ATV320 machine drives. Plants that already run Schneider PLCs and switchgear often keep drives on the same platform. See the Schneider AC drive page.

Frecon

The FR01 smart inverter, FR150A, FR500A and low power drives cover machine and general industrial duty, and the FR150T/FR500T is a solar (PV) water pump inverter. Details are on the Frecon AC drive page.

Getting the Drive Size Right

Start from the motor plate, not the kW printed on a purchase request. The drive must deliver the motor's full rated current continuously, and more than that for a short time if the load is hard to start. An extruder screw full of cold material, a loaded conveyor or a screw compressor asks for full torque from standstill, so those constant torque jobs need a drive with generous overload capacity. A centrifugal pump or fan asks for very little torque at low speed and is the easiest load a drive will see.

Next, confirm what the panel supplies, single-phase or three-phase and at what voltage, and how the speed will be set: from the keypad, a potentiometer, a 4-20 mA signal from a transmitter, digital presets or a PLC over Modbus. Loads with a lot of inertia that must stop quickly may need a braking resistor. Finally, note the motor cable length and the panel's ambient temperature, which matter a great deal in a Delhi summer.

VFD Applications Across Delhi NCR

Plastic, rubber and cable units in Bawana, Narela and Kundli: extruders, take-up and haul-off drives, and cooling water pumps where steady speed sets product quality.

Auto and two-wheeler component plants in Gurugram, Manesar and Faridabad: conveyors, washing machines, compressors and ventilation fans.

Electronics plants in Noida and Greater Noida: chilled water pumps, AHU fans and clean-room ventilation.

Packaging and printing units in Okhla and Mayapuri: unwinders, conveyors and blowers.

Keeping Drives Healthy in NCR Conditions

Delhi's hot summers and dusty industrial areas are hard on electronics. Most drive trips trace back to an overheated panel, a clogged filter or a loose terminal rather than to the drive itself. Size panel fans for summer temperatures, clean filters and heat sinks regularly, re-tighten power terminals and keep a copy of the parameters. Our low voltage AC drive maintenance checklist lists each step, and the general purpose AC drive guide explains the basics.

Schneider or Frecon: How NCR Buyers Usually Decide

Situation	Usual choice	Reason
The plant or end customer has a Schneider standard	Altivar	Same platform for spares, software and maintenance skills
An OEM building compact machines in volume	Altivar ATV12 / ATV310 / ATV320 or Frecon FR01 / low power drives	Small footprint at machine scale
Extruders, conveyors and general plant duty	Frecon FR150A / FR500A or Altivar general purpose	Fits the application and the budget
Solar (PV) water pumping	Frecon FR150T / FR500T	PV pump inverter with MPPT

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

Load Type Decides the Drive

Load	NCR examples	What it means
Variable torque	Chilled water pumps, AHU fans, cooling tower fans	Torque falls with speed; the biggest energy saving
Constant torque	Plastic extruders, conveyors, mixers, screw compressors	Full torque at low speed; more overload margin

A Typical VFD Application in Delhi NCR

Take a typical cable or plastic extrusion line in Bawana. The extruder screw motor sets output, and the haul-off at the end of the line must match it to hold the product dimension. Running both on AC drives lets the operator trim screw speed and haul-off speed from the panel, and a speed reference from the extruder drive can make the haul-off follow automatically. The extruder drive is sized for constant torque, because the screw needs its full torque at start-up and low speed.

VFD Mistakes to Avoid

Choosing a drive by kW and ignoring motor current and load type.
Panels without enough airflow for summer temperatures.
Clogged panel filters in dusty industrial estates.
Long motor cables with no consideration of output filtering.
Fast stops on high-inertia loads without a braking resistor.
No saved copy of drive parameters.

Why NCR Buyers Choose RB Automation for AC Drives

With two drive brands, we can offer Schneider where a plant has standardised on it and Frecon where it suits the application and budget. We also supply the PLCs, HMIs and transmitters that sit around the drive. Selection is handled by phone, WhatsApp and email, and orders ship from Ahmedabad by courier or road transport. See our PLC guide for Delhi NCR or the full range we supply to Delhi NCR.

Conclusion

A VFD sized by current and load type, installed in a well-ventilated panel, saves energy and protects the motor for years. Send your motor nameplate and application to RB Automation for a Schneider or Frecon recommendation supplied to Delhi NCR.

Frequently Asked Questions

Which AC drive brands do you supply to Delhi NCR?

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

Which VFD should I use on a plastic extruder?

An extruder is a constant torque load, so choose a drive with enough overload capacity for its starting and running torque, sized by motor current. Send the motor nameplate and we will recommend a model.

Are you an authorised Schneider Electric partner?

Yes. RB Automation is an authorised Schneider Electric partner and supplies Altivar drives, Modicon PLCs and Harmony HMIs, which customers in Delhi NCR can order from us.

Why do VFDs trip more often in summer?

High panel temperature is a common cause. Check that panel fans and filters are clean and sized for summer heat, and that heat sinks are free of dust.

What is the price of a VFD in Delhi NCR?

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.
