Servo Motor Supplier in Coimbatore: Buying Guide

Key Takeaways

Coimbatore uses servo motors on textile machinery, CNC retrofits, cut-to-length lines and packaging machines.
RB Automation supplies Rtelligent RSHA, RSNA, RSDA and RSM AC servo motors from about 50 W to 1 kW.
Size the servo from the motion profile: peak and RMS torque, top speed and inertia ratio.
Motor, matched drive, cables and servo reducer can be supplied together from Ahmedabad.

Some axes simply outgrow a stepper: a feed roll on a cut-to-length line that must start and stop many times a minute, a traverse that has to keep pace with a fast spindle, or the slides of an older lathe being given new life with modern controls. Coimbatore has all of these, and each calls for a servo motor. RB Automation is a servo motor supplier in Coimbatore, sending Rtelligent servo motors, matching drives and gearboxes from Ahmedabad and helping with sizing over phone, WhatsApp and email.

Where Coimbatore Puts Servo Motors to Work

Textile machinery

Builders of textile machines and accessories around Ganapathy and Peelamedu use servos on winding, traverse and take-up motions that must follow another axis or hold tension while running fast.

CNC retrofits

The district's many machine shops keep older lathes and milling machines running by renewing their controls. New servo motors, chosen from the existing ball screw and slide weight, bring back speed and repeatability.

Cut-to-length and feed lines

Lines that cut sheet, strip or coil to length rely on a servo-driven feed roll to place every cut accurately at production speed.

Packaging machines and SPMs

Packaging equipment for food units around Pollachi, and SPMs from SIDCO Kurichi and Malumichampatti, use servos for quick pick-and-place, pusher and sealing moves. Our article servo systems for packaging machines goes into this.

A Typical Servo Application in Coimbatore

Think of a typical cut-to-length line for sheet or coil that a Coimbatore machine shop builds or rebuilds. The feed roll must push a set length, stop dead, wait for the shear and go again, many times a minute. An AC servo motor on the feed roll, coupled through a servo reducer so the inertia of the rolls and coil is brought into a workable ratio, gives the acceleration and stopping accuracy that keep each piece within tolerance. The same shop, retrofitting an older lathe or mill, would size servo motors from the slide weight, ball screw pitch and rapid traverse speed, then reuse the mechanics while renewing the drives and control.

Servo Sizing Errors to Avoid

Checking only continuous torque and then running short of peak torque on acceleration.
Living with a very large inertia mismatch instead of adding a reducer.
No brake on an axis that gravity can pull down.
Encoder leads without screening or proper earthing.
A motor and drive from series that were not designed to pair.

Why a Servo Behaves Differently

A servo motor is always paired with a drive that watches its encoder and corrects the current continuously, so the shaft stays on the commanded path. Because the loop is always closed, the motor can run fast, accelerate hard, take a brief overload and still stop exactly where it should, even as the load varies.

Rtelligent Servo Motors and Accessories

Our AC servo motors come in four Rtelligent families: the RSHA, RSNA, RSDA and RSM series, together spanning roughly 50 W to 1 kW. That band covers the axes on most textile, packaging and light machine-tool equipment.

For special cases there is the integrated low-voltage servo motor, which carries its drive inside the motor body for compact or mobile machines, and the super short DC servo motor for spots with little length behind the flange. To raise torque and tame inertia, add a servo reducer (planetary gearbox). The AC servo motor and servo system pages list every series.

Six Steps to Size a Servo Motor

Describe the move: how far, how fast, how quickly it must accelerate and how long it rests.
Calculate torque: both the RMS value over the full cycle and the peak during acceleration, with friction, gravity and cutting or pressing forces included.
Confirm speed: the highest motor speed, after allowing for any gear ratio.
Check inertia: if the load is much heavier in inertia than the motor rotor, a reducer brings the ratio down and makes tuning easier.
Brake: any axis that gravity can move needs one.
Drive: motor and drive must be matched; see our servo drive guide for Coimbatore.

Is a Closed-Loop Stepper Enough?

Slow indexing and short feeds can often run on a closed-loop stepper for less money; our stepper servo drive guide for Coimbatore explains when. Choose a servo when the axis is quick, runs without pause or faces a changing load. The article stepper motor vs servo motor sets the two side by side.

Why Choose RB Automation for Servo Motors

As Rtelligent's technical partner we supply the motor, drive, cables and gearbox together, so they arrive as one matched axis. We work from Ahmedabad and handle sizing and set-up questions remotely rather than through site visits. See every product we supply to the city on the industrial automation supplier in Coimbatore page.

Conclusion

A servo motor sized from the real motion profile gives a Coimbatore machine its speed and accuracy without wasted cost or overheating. Send RB Automation the move, the load and the controller, and we will recommend a matched Rtelligent motor, drive and reducer.

Frequently Asked Questions

Which servo motors do you supply to Coimbatore?

We supply Rtelligent RSHA, RSNA, RSDA and RSM series AC servo motors, integrated low-voltage servo motors, super short DC servo motors and servo reducers, dispatched from Ahmedabad.

Can your servo motors be used for a CNC retrofit?

Yes, for axes within the range of the Rtelligent AC servo motors, roughly 50 W to 1 kW. Share the ball screw pitch, slide weight, required speed and the controller you will use, and we will suggest motors and drives.

Are servo motors suitable for textile machinery?

Yes. Servo motors suit winding, traverse and take-up axes that must follow another motion or hold tension at speed. Slower indexing axes may manage with a closed-loop stepper.

Do you supply the drive and gearbox with the servo motor?

Yes. We supply matched Rtelligent servo drives, cables and servo reducers along with the motor, so the axis comes as one package.

What is the price of a servo motor in Coimbatore?

There is no fixed price list. The price depends on the series, power, encoder, brake, matching drive and quantity. Use the form on this page, call +91 8511104864 or email contact@rbautomate.com for a quotation.
