Key Takeaways
- Bengaluru plants use VFDs on machine tool spindles, conveyors, pumps and fans.
- We supply Schneider Electric Altivar and Frecon AC drives to the city from Ahmedabad.
- Size the drive on motor current and load behaviour, then check supply, control method and braking.
- Cabinet temperature and cable routing near CNC electronics deserve as much attention as the drive model.
Across Bengaluru's industrial ring, AC drives do two quite different jobs. In the machine tool and SPM workshops of Peenya and Bommasandra they give speed control to spindles, coolant pumps and swarf conveyors. In the vehicle and component plants at Bidadi, Narasapura, Hoskote and Attibele they run conveyors, compressors and ventilation fans, and in process and textile units around Harohalli, Doddaballapur and Dobbaspet they drive pumps, blowers and winders. As an AC drive and VFD supplier in Bengaluru, RB Automation dispatches Altivar drives from Schneider Electric and inverters from Frecon out of Ahmedabad, and helps size them by phone, WhatsApp and email.
What a VFD Changes on a Motor
A variable frequency drive rectifies the mains supply and rebuilds an output whose frequency and voltage it can vary, so a standard induction motor can run at any speed in its range. The motor starts gently instead of drawing a heavy inrush, accelerates and decelerates on a set ramp and is protected against overload and phase faults. Where a fan or pump has been throttled by a damper or valve, slowing the motor instead usually reduces the power drawn.
Drive Ranges Supplied to Bengaluru
Schneider Electric Altivar
RB Automation is an authorised Schneider Electric partner. The range includes Altivar low voltage drives (ATV12 up to 4 kW, ATV310 up to 30 kW and ATV320 for machines), and Altivar general purpose drives including the ATV61 for pump, fan and high-torque duty. Sites already running Schneider PLCs and switchgear tend to keep Altivar for common spares and software. More on the Schneider Electric drives page.
Frecon
The FR01 smart inverter has a narrow book-type body, single-phase 220 V or three-phase 380 V input and sensorless vector control, which suits tight machine cabinets. The FR150A covers small motors with built-in PID and RS-485 Modbus, the FR500A handles general industrial duty, and the FR150T/FR500T are solar water pump drives. The low power AC drives and Frecon AC drive pages list the full family.
Sizing a VFD in Five Steps
- Start with the nameplate: rated current is the first sizing figure; kW alone can mislead.
- Classify the load: fans and centrifugal pumps need less torque at low speed; spindles under cut, conveyors and mixers need full torque across the range and more overload margin.
- Confirm the supply: one phase or three, and the voltage measured at the cabinet.
- Plan the control: keypad, potentiometer, analogue reference, digital speeds or Modbus from a PLC.
- Handle stopping: a heavy spindle or flywheel that has to halt fast can push energy back into the drive, so plan a braking resistor.
Bengaluru Applications
Machine tools and SPMs
Builders and retrofitters in Peenya, Bommasandra and Jigani fit VFDs on spindle motors of simpler machines, coolant pumps and chip conveyors. Placing the drive away from sensitive CNC and encoder wiring, and using shielded motor cable, avoids interference problems.
Automotive and component plants
At Bidadi, Narasapura, Hoskote and Attibele, drives run assembly conveyors, paint-shop and ventilation fans, and air compressors.
Process, textile and utilities
Units in Harohalli, Doddaballapur and Dobbaspet use drives on transfer pumps, blowers, cooling fans and textile winding machines, while tech parks and campuses across the city fit them to booster pumps and air-handling fans.
Keeping Drives Healthy
When a drive trips repeatedly, the cause is usually the cabinet rather than the electronics: clogged filters, a dead fan, fine metal dust from machining or a terminal that has worked loose. A quarterly clean, a torque check on power terminals and a saved parameter file prevent most call-outs. Our maintenance checklist for low voltage AC drives lists each step.
Drive Ranges Compared
| Model | Make | Where it fits in Bengaluru |
|---|---|---|
| Schneider Altivar ATV12 / ATV310 / ATV320 | Schneider Electric | Machines and lines built on Schneider controls |
| Schneider Altivar ATV61 | Schneider Electric | Large pumps, fans and high-torque duty |
| Frecon FR01 | Frecon | Narrow machine cabinets, single- or three-phase input |
| Frecon FR150A | Frecon | Small motors needing built-in PID and Modbus |
| Frecon FR500A | Frecon | Everyday plant duty on conveyors, pumps and mixers |
| Frecon FR150T / FR500T | Frecon | Solar-powered water pumping |
Ratings vary from model to model; check the individual product page, or simply share the motor plate details.
How the Load Shapes the Drive Choice
| Load | Bengaluru examples | Drive consideration |
|---|---|---|
| Variable torque | Ventilation fans, cooling tower fans, centrifugal pumps | Lower torque at low speed; best energy savings |
| Constant torque | Spindles under cut, conveyors, chip conveyors, mixers | Full torque at low speed; higher overload margin |
| High inertia | Large spindles, flywheels, big fans | Longer ramps or a braking resistor |
A Typical AC Drive Application in Bengaluru
Picture a component plant at Bidadi or Hoskote where a long assembly conveyor is started direct-on-line, so pallets jolt at every start and the line speed cannot be changed when the product mix changes. Fitting an AC drive gives a smooth ramp-up, a speed set from the line PLC over Modbus, and a controlled stop at the end of shift. On the same site, the paint-shop exhaust fans can be slowed when the booths are idle rather than running flat out all day, cutting power use and noise.
VFD Mistakes Worth Avoiding
- Choosing by kW without checking current and load type.
- Installing in a cabinet with blocked or missing ventilation.
- Running VFD output cables beside CNC encoder and signal wiring.
- Stopping heavy loads fast without a braking resistor.
- Not saving the parameter set after commissioning.
Your VFD Enquiry Checklist
- A photo of the motor plate showing kW, amps and volts
- What the motor drives and how many starts per hour
- Incoming supply, one phase or three
- How speed will be set: keypad, potentiometer, analogue, digital or Modbus
- Brand preference, if any, and how many drives
Why Choose RB Automation for VFDs in Bengaluru
Carrying two brands means the recommendation follows your plant, not our catalogue: Altivar for sites already built on Schneider Electric controls, Frecon where a compact or budget-conscious drive suits the duty better. The controller, operator panel and sensors that sit beside the drive can be added to the same order. Everything ships from Ahmedabad with sizing handled remotely; call +91 8511104864, WhatsApp +91 9898739737 or email contact@rbautomate.com. Controls for the same machine are covered in the Bengaluru PLC guide, and the Bengaluru supplier page lists every family.
Conclusion
Whether it drives a spindle in Peenya, a conveyor at Bidadi or a pump in Doddaballapur, a VFD sized on current and load behaviour shields the motor from stress and puts speed under your control. Photograph the nameplate, describe the load and send both to RB Automation; we reply with a suitable Altivar or Frecon model.
