Servo Motor Supplier in Chennai: Buying Guide

Key Takeaways

RB Automation supplies Rtelligent RSHA, RSNA, RSDA, RSM and RSMA AC servo motors to Chennai from its Ahmedabad base.
Size a servo on peak torque during acceleration, RMS torque over the cycle, top speed and the load-to-motor inertia ratio.
Press feeders, gantries, assembly cells and packaging machines are the typical servo axes in Chennai plants.
Integrated low-voltage and 48 V DC servo motors suit compact and battery-powered equipment such as AGVs.

Chennai's automotive supply chain runs on short cycle times. Sheet metal stampings, machined parts and sub-assemblies move through press lines, gantry loaders and assembly cells that have to be both fast and repeatable, and that is where a servo motor replaces a stepper. Packaging and electronics machinery in the city adds its own high-speed axes. RB Automation is a servo motor supplier in Chennai, shipping the Rtelligent servo range with matched drives and gearboxes from Ahmedabad.

Servo Applications Across Chennai

Press lines and sheet metal in Ambattur and Gummidipoondi

Servo roll feeders and transfer axes deliver strip and blanks to power presses with a consistent feed length at high stroke rates.

Assembly and gantry automation around Sriperumbudur and Oragadam

Gantry loaders, pick-and-place cells, screw-driving and press-fit stations on supplier lines use servo axes where moves are long, fast and frequent.

Packaging, electronics and intralogistics

Packaging machines use servos for film feed, sealing and cutting in register. Integrated low-voltage and DC servo motors suit AGVs and battery-powered handling equipment inside large plants.

What Makes a Servo Motor Different

A servo motor always works in closed loop with its drive. A high-resolution encoder reports the shaft position continuously, and the drive adjusts current many times per second to follow the commanded profile. The result is high speed, quick acceleration, smooth motion and a large short-term overload reserve, while the position stays accurate even as the load changes from one part to the next.

Servo or Closed-Loop Stepper?

A servo is the right choice for high speed, varying loads or continuous motion. For slower indexing and clamping, a closed-loop stepper often does the job at lower cost; compare them in our Chennai stepper servo drive guide and the stepper motor vs servo motor article.

Sizing a Servo Motor Correctly

Draw the motion profile: stroke, move time, acceleration, deceleration and dwell for each step.
Calculate torque: peak torque while accelerating, and RMS torque over the full cycle, including friction, gravity and process forces such as a feed or press load.
Check speed: the highest motor speed needed, before or after any gearbox.
Watch inertia: a load far heavier in inertia than the motor rotor is hard to tune; a reducer brings the ratio down.
Add a brake to any axis that can fall when power is removed.
Pair the drive: motor and drive must be a matched set. See our Chennai servo drive guide.

Servo Motors Supplied to Chennai

RSHA series: 200 W to 1 kW in 60 and 80 mm frames, with a 17-bit magnetic or 23-bit optical absolute encoder, an optional brake and a 3x overload capability.
RSNA series: 50 W to 1000 W on 220 V, with IP65 and IP66 options for areas exposed to coolant or washdown.
RSDA series: 100 W to 1 kW with an ultra-short body for tight machine envelopes.
RSM series and the RSMA 5-pole-pair high performance motor.
IDV integrated low-voltage servo motor: 50 W to 1000 W on 18-48 VDC, with the drive built in and RS-485 or CANopen control.
S01 super short DC servo motor: 48 V, 200 W to 1000 W, with an optional brake for Z axes.
Servo reducers in 42SPX, 60SPX, 90SPX and 120SPX sizes.

A Typical Servo Application in Chennai

Take a typical servo roll feeder on a power press in an Ambattur stamping unit making brackets for vehicle seats. The feeder must push a set length of strip into the die during the short window when the press is at the top of its stroke, then hold still while the die closes. A servo motor with a reducer gives the fast acceleration and stiff hold this needs, and changing the feed length for a new bracket is a parameter change rather than a mechanical adjustment. Sizing is driven by the peak torque in that brief feed window, so the motion profile matters more than the average load.

Where a Servo Beats a Closed-Loop Stepper

Requirement	AC servo motor	Closed-loop stepper
Long, fast moves	Strong	Torque fades at speed
Peak force during acceleration	Large short-term overload	Little reserve
Continuous running	Designed for it	Better for start-stop moves
Commissioning effort	Gain tuning needed	Close to plug and play
Budget	Higher	Lower

Common Servo Motor Mistakes to Avoid

Sizing on continuous torque and forgetting the peak torque during acceleration.
Running a very high load-to-rotor inertia ratio with no reducer, which makes tuning unstable.
Omitting a brake on a vertical or inclined axis.
Using unshielded or poorly earthed encoder cables near press and welding equipment.
Pairing a motor with a drive from a different, unmatched series.

Why Choose RB Automation for Servo Motors

As Rtelligent's technical partner, we supply the servo motor, matched drive, cables and reducer as one package, and help with sizing by phone, WhatsApp and email before you buy. Chennai orders ship from Ahmedabad. See the full automation range we supply in Chennai.

Conclusion

A servo motor sized on its real motion profile gives a Chennai press line, gantry or packaging machine the speed and accuracy it needs without overheating or oversizing. Share the profile and load with RB Automation and we will recommend a matched Rtelligent motor, drive and reducer.
