Stepper Servo Drive Supplier in Ludhiana: Buying Guide

Key Takeaways

Closed-loop stepper servo drives suit Ludhiana feeders and transfer units where one missed step stops the line.
RB Automation supplies the Rtelligent T42, T60 Plus, T86, T60S/T86S and hybrid DS86 to Ludhiana from Ahmedabad.
Wire the drive's alarm output to the PLC, or the main benefit of closed loop is lost.
An open-loop machine can often be upgraded by changing only the motor and drive.

Feeders and transfer units are the heartbeat of Ludhiana's press shops, fastener plants and bicycle part lines. They push strip, wire, blanks or tubes into tooling over and over, shift after shift. Put an open-loop stepper on such an axis and it works well until a coil snags or a blank sticks; then the motor slips, the controller has no idea, and the next stroke lands in the wrong place. Fixing that blind spot does not always need a full AC servo. RB Automation is a stepper servo drive supplier for Ludhiana, sending Rtelligent closed-loop drives and motors from Ahmedabad, and we help you judge when this middle option is the right one.

Ludhiana Machines That Benefit Most

Wire and blank feeders in fastener and forging units

Units around Dhandari Kalan, Sahnewal and Kanganwal feed wire or blanks into heading, cutting and forming tools. A feed that falls short ruins the part and can damage the tool, so position checking pays for itself.

Rim, spoke and tube handling for bicycle makers

Machine builders in Focal Point fit closed-loop axes where length and position must be right on every cycle.

Gauging and marking for auto and tractor parts

Stations that measure or mark parts need the head to arrive where the program says it is.

Rebuilt machines that keep losing position

Often the cheapest cure is to change only the motor and drive, keeping the existing PLC and its pulse output.

How a Closed-Loop Stepper Drive Thinks

The motor carries an encoder, and the drive keeps comparing the counted pulses with the real shaft angle. A small lag is quietly made up. A large one, the sign of a jam, trips an alarm output so the controller can halt the cycle. Since the drive only sends the current the load actually needs, the motor stays noticeably cooler than one driven open loop at full current.

Drives in the Rtelligent Closed-Loop Range

T42 for small closed-loop motors on light axes.
T60 Plus, a frequent pick for mid-size feeders and indexers.
T86 for bigger frames moving heavier loads.
T60S and T86S, Rtelligent's newer S-series drives.
DS86, a hybrid 2-phase model for large frames.

Pair them with 2-phase closed-loop stepper motors, or with the brake and Z-signal versions from our stepper motor guide for Ludhiana. An overview of the family is on the stepper servo drive page.

Open Loop, Closed Loop or Full Servo?

An open-loop stepper is the cheapest and is fine when the load is light and never changes. A closed-loop stepper adds position checking, an alarm and a cooler motor while staying almost tuning-free, which suits most feed and index axes. A full AC servo earns its higher cost on fast, continuous or high-inertia axes such as a quick press feeder; see the servo drive guide for Ludhiana. Our article stepper motor vs servo motor goes deeper.

Five Checks Before Ordering

Size the drive from the closed-loop motor's frame and rated current.
Find out what pulse signal your PLC or controller puts out, and at what voltage level.
Check the DC or AC supply inside the cabinet.
Plan an input on the PLC for the drive's alarm, and for in-position if the sequence needs it.
For a slide that can fall, order a brake motor and wire the brake release.

Matching a Closed-Loop Drive to the Feeder

Feeder or axis	Suggested drive	Why
Light gauging or marking head	T42	Small frame, light load
Strip, blank or spoke feeder	T60 Plus	Mid-size motor, common feeder duty
Heavy wire feed or transfer	T86	Larger frame, more torque
Upgrading an existing open-loop machine	T60S or T86S	Newer S-series drives
Large closed-loop axis	DS86	Hybrid 2-phase drive for big frames

Exact current and voltage figures are on each product page, and we check the drive against your motor before it ships.

A Typical Closed-Loop Upgrade in Ludhiana

Consider a typical wire feeder in a fastener unit that pushes wire into a heading or cutting tool. It runs on an open-loop stepper, and whenever the coil snags the motor slips. The next blank comes out short, and a whole batch of faulty screws can reach inspection before anyone spots it. Swapping in a closed-loop stepper motor and a T86 drive keeps the pulse signal from the existing PLC unchanged, yet the drive now notices the shortfall. With its alarm wired to a spare PLC input, the press halts at the snag, the operator frees the coil and production carries on without scrap.

Fitting Errors That Waste the Upgrade

Alarm output left unconnected, so the PLC never learns the feed has failed.
Encoder leads swapped between two axes during a rebuild.
A closed-loop stepper chosen for a fast press feeder that really needs an AC servo.
Brake control forgotten on a lifting or vertical slide.

Information We Need to Quote a Stepper Servo Drive

Current motor and drive, or the load, feed length and speed
PLC model and its pulse output type
Supply voltage in the cabinet
Whether a brake or Z-signal encoder is wanted
Number of axes

Why Choose RB Automation for Ludhiana

Being Rtelligent's technical partner lets us quote the drive, the paired motor and, if wanted, the PLC together. Sizing and wiring questions are answered by our Ahmedabad team on phone, WhatsApp and email. All our product families for the city are on the industrial automation supplier in Ludhiana page.

Conclusion

A wire feeder in Sahnewal or a tube feed in Focal Point that must never slip, yet does not need servo speed, is the classic job for a closed-loop stepper. Tell RB Automation the motor, load and controller, and we will suggest a matched Rtelligent drive and motor.

Frequently Asked Questions

Why use a closed-loop stepper drive on a press or wire feeder?

A closed-loop drive reads the motor encoder, corrects small position errors and raises an alarm if the feed cannot follow. On a feeder that means the machine stops instead of pressing or cutting a part in the wrong place.

Which stepper servo drives do you supply to Ludhiana?

We supply Rtelligent pulse-control closed-loop drives T42, T60 Plus and T86, the T60S/T86S S series and the hybrid DS86, along with matching closed-loop stepper motors, dispatched from Ahmedabad.

Do I need to change my PLC to move to closed loop?

In many cases no. The closed-loop drive accepts the same pulse and direction command, so often only the motor and drive change. Share your PLC model and its pulse output to confirm.

When is an AC servo a better choice than a stepper servo drive?

Choose an AC servo when the axis runs at high speed, moves a heavy inertia or runs continuously, as on a fast press feeder. For slower indexing and feeding, a closed-loop stepper is usually enough.

What is the price of a stepper servo drive in Ludhiana?

There is no fixed price list. RB Automation quotes each requirement, because the price depends on the drive model, the matching motor and the quantity. Use the form on this page, call +91 8511104864 or email contact@rbautomate.com.
