Key Takeaways
- Pune plants run conveyors, compressors, coolant pumps, paint shop fans and machine spindles on AC drives.
- RB Automation supplies Schneider Electric Altivar and Frecon VFDs to Pune from Ahmedabad.
- Size the drive on motor current and load type; conveyors and spindles need more overload margin than fans and pumps.
- Heat, dust and long motor cables cause more drive trouble than the drive model, so plan the panel as well.
Most motors in a Pune automotive or engineering plant are not on the production machines at all. They drive the conveyors between stations, the coolant and washing pumps, the compressors, the exhaust and paint shop fans and the cooling towers. Running them at the right speed, with a soft start, saves energy and wear. RB Automation is an AC drive and VFD supplier in Pune working from Ahmedabad: we dispatch Schneider Electric Altivar and Frecon inverters and check each one against the motor nameplate and the kind of load it will run.
How a VFD Controls an AC Motor
A variable frequency drive rectifies the incoming supply and rebuilds an output of adjustable frequency and voltage. Since an induction motor's speed follows frequency, the drive sets the speed. Along the way it gives a gentle start instead of a current surge, a controlled stop, and protection against overload and phase faults. On centrifugal pumps and fans, slowing the motor rather than throttling the flow usually cuts power sharply, which is where most energy savings come from.
Drives Available to Pune Plants
Schneider Electric Altivar
RB Automation is an authorised Schneider Electric partner. Two Altivar families are available, the low voltage and the general purpose ranges, a natural fit for plants whose panels and PLCs are already Schneider. An overview sits on our Schneider drives page.
Frecon
From Frecon we offer the low power series for small motors, the FR01 smart inverter, the FR150A and FR500A, and the FR150T/FR500T solar (PV) water pump inverter. Everything is grouped on our Frecon inverters page.
VFD Duties in Pune Industry
Conveyors and transfer lines
Assembly plants in Chakan, Talegaon and Ranjangaon move parts and sub-assemblies on roller, belt and chain conveyors. A drive lets each section run at its own speed and start without jerking the load.
Machine tool spindles and coolant
Machining shops in Bhosari and Pimpri-Chinchwad use drives on spindles, coolant pumps and chip conveyors, where constant torque at low speed matters.
Compressors, fans and cooling towers
Utility blocks across Sanaswadi, Hadapsar and Urse run compressors, exhaust fans and cooling tower fans that spend much of the day below full load, the classic case for speed control.
Process plants
Units at Kurkumbh and Baramati MIDC use drives on agitators, dosing and transfer pumps and blowers.
Sizing a VFD Correctly
- Read the nameplate: power, voltage and above all rated current. Size the drive by current.
- Know the load: fans and centrifugal pumps are variable torque; conveyors, spindles, mixers and positive displacement pumps are constant torque and need more overload capacity.
- Count the starts: frequent starting and stopping or heavy inertia may call for a braking resistor.
- Check the incoming power: whether the panel offers one phase or three.
- Decide who gives the speed command: the operator on the keypad, a 0-10 V or 4-20 mA signal, fixed speeds on inputs, or the PLC over a network.
- Plan the panel: airflow, oil mist, ambient heat and how far away the motor is.
Keeping Drives Running
Drives in machining areas pick up oil mist and fine dust, and panels near furnaces or paint ovens run hot. Clean filters and heat sinks on a schedule, keep the cabinet fan working, re-tighten power terminals and save a copy of the parameters. Our low voltage AC drive maintenance checklist walks through each step, and the general purpose AC drive guide explains the basics.
Which Inverter Family for Which Pune Job
| Pune job | Inverter family | Maker |
|---|---|---|
| Utility pumps and fans on a Schneider-standard site | Altivar low voltage or general purpose | Schneider Electric |
| Conveyor sections on an assembly line | Altivar general purpose, FR150A or FR500A | Schneider Electric or Frecon |
| Small motors on SPMs and washers | Low power series or FR01 smart inverter | Frecon |
| Solar (PV) water pumping | FR150T / FR500T | Frecon |
Ratings and input options vary within each family; the product pages list them, or a nameplate photo lets us pick for you.
Load Types on a Typical Pune Site
| Load | Torque behaviour | What the inverter must handle |
|---|---|---|
| Exhaust, paint booth and cooling tower fans | Variable torque | Largest energy savings from running slower |
| Centrifugal coolant and water pumps | Variable torque | Speed control can replace a throttling valve |
| Roller, belt and chain conveyors | Constant torque | Full torque at low speed, smooth acceleration |
| Machine spindles and chip conveyors | Constant torque | Overload margin for starts and heavy cuts |
| Agitators and positive displacement pumps | Constant torque | Check starting torque and overload capacity |
A Typical VFD Application in Pune
A typical paint shop at a vehicle or component plant in Talegaon or Chakan has supply and exhaust fans on its spray booths and ovens that often run at full speed through the whole shift, with dampers setting the airflow. Fitting AC drives to the fan motors and linking them to the booth pressure control lets the fans run only as fast as the booth needs, for example slowing during breaks and colour changes. That reduces power use, removes the inrush current at every start and cuts wear on belts and bearings. The same thinking applies to central coolant pumps on machining lines that today run against a part-closed valve.
Why Inverters Trip in Pune Plants
- The inverter was picked from the kW figure while the motor draws more current than it can give.
- Cabinet filters clog with oil mist and grinding dust, and the heat sink overheats.
- A long run to the motor uses ordinary cable with no screen and no output filter.
- A loaded conveyor is asked to stop in a second with nowhere for the braking energy to go.
- Nobody kept the parameter set, so a replacement takes hours to commission.
Checklist for an Inverter Enquiry
- A photo of the motor nameplate
- What the motor drives, and how many starts per hour
- Whether the panel has one-phase or three-phase power
- Where the speed command comes from
- Schneider or Frecon preference, and how many units
Why Choose RB Automation for VFDs in Pune
Carrying two drive brands lets us follow your plant standard: Altivar where the site already runs Schneider, Frecon where a machine builder wants a capable inverter at a sharper cost. Controllers, operator panels and instruments for the same panel come from us too. Orders are dispatched from Ahmedabad, and sizing questions are answered on +91 8511104864, WhatsApp +91 9898739737 or contact@rbautomate.com.

Frequently Asked Questions
Which AC drives do you supply in Pune?
We supply Schneider Electric Altivar low voltage and general purpose AC drives as an authorised Schneider Electric partner, and Frecon FR01, FR150A, FR500A, FR150T/FR500T and low power AC drives.
Which VFD should I use on a conveyor or machine spindle?
Conveyors and spindles are constant torque loads, so the drive must deliver full torque at low speed and have enough overload capacity for starts. Size it by the motor's rated current and tell us how often it starts and stops.
Will a VFD save energy on a compressor or cooling tower fan?
On fans and centrifugal pumps that often run below full demand, speed control usually saves energy compared with throttling or on-off control. Compressor savings depend on the compressor type and its control, so share the details.
Is RB Automation an authorised Schneider Electric partner?
