Stepper Servo Drive Supplier in Delhi NCR: Buying Guide

Key Takeaways

Closed-loop stepper servo drives keep feed length accurate on the pouch, label and carton machines built in the NCR.
We supply Rtelligent T42, T60 Plus, T86, the T60S/T86S S series and the hybrid DS86 to Delhi NCR from Ahmedabad.
The drive reads the motor encoder, corrects small errors and raises an alarm when the axis cannot keep up.
Many open-loop machines can be upgraded by changing only the motor and drive, keeping the existing PLC.

A pouch machine that cuts one bag a few millimetres short every hundred cycles, or a label applicator that slowly drifts off register, is a familiar headache for NCR machine builders. The cause is usually an open-loop stepper that slipped under load. RB Automation is a stepper servo drive supplier in Delhi NCR and ships the Rtelligent closed-loop range from Ahmedabad, so builders and plant maintenance teams can close that gap without moving to a full AC servo system.

How a Closed-Loop Stepper Drive Works

The motor carries an encoder. The drive compares where the shaft should be with where the encoder says it is and adds current to pull it back on track. If the error passes a set limit, the drive trips an alarm that the PLC can use to stop the machine. Because current follows the load rather than sitting at full value all the time, the motor also runs cooler than an open-loop one doing the same job.

Rtelligent Closed-Loop Drives We Supply to the NCR

T42 for small closed-loop motors on light axes.
T60 Plus for the mid-size motors found on most packaging and printing axes.
T86 for larger frames and heavier feeds.
T60S and T86S, the S series of 2-phase closed-loop drives.
DS86 hybrid 2-phase closed-loop drive.

Each one pairs with a 2-phase closed-loop stepper motor, a brake motor or a Z-signal encoder motor. Motor options are explained in our stepper motor guide for Delhi NCR, and the whole family is on the stepper servo drive page.

Where Closed Loop Fits Between Stepper and Servo

An open-loop stepper is the cheapest axis but has no way of knowing it missed a step. An AC servo offers the most speed, the best response to changing loads and strong overload capacity, but it needs tuning and costs more. A closed-loop stepper sits between them: position is verified, set-up stays simple and the cost stays close to a stepper. For indexing, feeding and short positioning moves it is often the sweet spot. Fast, continuous or high-inertia axes still belong to a servo, covered in our servo drive guide for Delhi NCR. The article stepper motor vs servo motor goes deeper.

Choosing a Stepper Servo Drive

Begin with the motor frame and current; the drive size follows from it.
Confirm the pulse output type and voltage level of your PLC or controller.
Check the DC supply available in the cabinet.
Plan to wire the alarm and in-position signals back to the PLC.
On vertical axes, select a brake motor and wire the brake output.

Closed-Loop Stepper Axes Across Delhi NCR

Pouch, label and carton machine builders in Okhla, Mayapuri and Wazirpur use closed-loop drives on film and web feeds where length accuracy decides product quality. SPM builders in Bawana and Narela fit them on transfer and clamping moves that meet changing loads. Converting lines at Noida and Faridabad, and assembly stations in the Gurugram and Manesar component belt, use them where a stepper is fast enough but a silent position error is not acceptable.

Closed-Loop Stepper Drives Side by Side

Drive	Family	Motor frame	Where it fits
T42	Pulse-control closed loop	Small	Light pushers and positioning axes
T60 Plus	Pulse-control closed loop	Mid	Film, label and carton feeds
T86	Pulse-control closed loop	Large	Heavier feeds and transfer axes
T60S / T86S	S series	Mid to large	General closed-loop builds and upgrades
DS86	Hybrid closed loop	Large	Heavier closed-loop axes

Exact current and voltage limits are listed on each product page; we confirm the drive-motor pair before you order.

Open Loop, Closed Loop and Servo Compared

Point	Open-loop stepper	Closed-loop stepper	AC servo
Position check	None	Encoder with alarm	Encoder with full servo loop
Set-up effort	Minimal	Minimal	Needs tuning
Speed range	Low to medium	Low to medium	High
Relative cost	Lowest	Moderate	Highest

A Typical Closed-Loop Upgrade in Delhi NCR

Take a typical label applicator on a bottling line in an NCR plant. The label web is advanced by an open-loop stepper, and when the roll is nearly empty or the web snags, a label lands slightly off position. Changing the motor to a closed-loop stepper and the drive to a T60 Plus keeps the PLC's pulse command unchanged, but the drive now corrects small errors and flags any it cannot recover. Wiring that alarm into the PLC stops the line at the first bad label instead of the hundredth.

Mistakes When Moving to Closed Loop

Leaving the alarm output unconnected, so the PLC never learns of a fault.
Mixing up encoder cables between two axes during installation.
Expecting a closed-loop stepper to match servo speed on a fast, high-inertia axis.
Forgetting brake wiring on a vertical axis.

Why Choose RB Automation for Stepper Servo Drives

We are Rtelligent's technical partner, so the drive, motor, encoder cable and controller come from one source. We do not run a service team in the NCR; instead our engineers help with selection and wiring questions by phone, WhatsApp and email, and orders are dispatched from Ahmedabad. All our product families are listed on the industrial automation supplier in Delhi NCR page.

Conclusion

When an axis must not lose position but does not need full servo performance, a closed-loop stepper servo drive is usually the most economical answer. Send RB Automation your motor, load and controller details for a matched Rtelligent recommendation supplied to Delhi NCR.

Frequently Asked Questions

What does a stepper servo drive add over an open-loop stepper driver?

It reads an encoder on the motor, corrects position errors as they happen and raises an alarm if the motor cannot follow. It also adjusts current to the load, so the motor runs cooler.

Which closed-loop stepper drives do you supply to Delhi NCR?

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

Can a closed-loop stepper fix feed-length errors on a pouch or label machine?

In many cases yes, if the error comes from the motor slipping under load. The drive corrects small errors and alarms on large ones. Share the machine details so we can check the axis.

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

Usually not. Most upgrades change only the motor and drive and keep the controller's pulse output. Send us the existing motor and controller details to confirm.

What is the price of a stepper servo drive in Delhi NCR?

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.
