When is a servo motor with an integrated controller a good choice?

The demands on mechanical engineering are increasing: shorter development times, rising cost pressures, and, at the same time, greater flexibility. This is exactly where servo motors with integrated controllers come into play—such as the esitron esiMot.
But when is this solution truly worthwhile?

First of all: What is a servo motor with an integrated controller?

An integrated servo drive combines the motor, power electronics, and control system into a single compact unit. Instead of installing the motor and servo controller separately in the control cabinet, the “intelligence” is located directly on the motor.

The result:

• fewer components
• less cabling
• less complexity

When the control cabinet becomes the bottleneck

Traditional drive solutions take up space in the control cabinet—and that space is becoming increasingly scarce.

With integrated drives such as the esitron esiMot:

• much of the control panel technology is eliminated
• cooling and energy requirements are reduced
• Installation and hardware costs are decreasing

-> Particularly relevant for modular machines and decentralized system designs

When commissioning time is critical

Time is a critical factor in mechanical engineering.

Integrated servo drives enable:

• preconfigured systems
• Quick plug-and-play integration
• fewer wiring errors

-> Result: significantly shorter time to market

When Cabling Becomes a Cost Factor

Especially on machines with many axes, the number of cables, terminals, and the amount of installation work can really add up.

A decentralized approach:

• significantly reduces cable runs
• simplifies installation
• improves clarity

-> Particularly advantageous in the material handling and packaging industries

When machines are built using a modular design

Modern machines are increasingly being designed with a modular structure.
With solutions such as the esitron ESY System:

• Drives can be easily scaled
• Modules can be operated independently of one another
• the reusability of machine modules is increased

-> Ideal for flexible production concepts

When hygiene and size are critical

In sectors such as the food industry, specific requirements apply:

• smooth surfaces
• minimal heating
• compact design

Integrated drives offer clear advantages in this regard:

• fewer external components = fewer edges where dirt can accumulate
• Optional hygienic design variants
• lower housing temperatures (e.g., through cooling solutions)

---

When complexity needs to be reduced

Many mechanical engineers are struggling with increasing system complexity.

• fewer interfaces
• less coordination effort
• clearly defined system architecture

-> In short: “Everything under one roof”

Conclusion: When is it really worth it?

A servo motor with a built-in controller is particularly worthwhile if you:

✔ Want to reduce control cabinet costs
✔ Need to speed up commissioning
✔ Want to implement modular machine designs
✔ Want to minimize cabling effort
✔ Need hygienic or compact solutions

Practical tip:
The earlier integrated drives are taken into account during machine design, the greater the economic benefit.
