What is Marsilli?
Marsilli is an Italian manufacturer of winding and assembly systems for electric motors and coils, with more than 80 years of history in the field. According to its website, it builds machines ranging from single-spindle units to 24-spindle systems, handling wire from 0.02 to 2.5 mm at speeds up to 25,000 RPM, and it covers both coil winding (spindle and flyer methods) and motor winding (including needle winding on open and closed stators). Its stated industries include automotive, appliances, electromechanical applications, RFID and consumer electronics.
Marsilli
What it offers beyond machines
The site lists services that matter for buyers planning production: co-engineering, refurbishment and retooling, training, and a customer platform (My.Marsilli), plus certified pre-owned equipment and stand-alone systems alongside full production lines. It also highlights e-traction and motor/coil solution areas, and publishes ISO 9001, 14001, 45001 and 27001 certifications.
Who it suits
- Motor and coil manufacturers needing customized winding equipment rather than off-the-shelf units, especially where precision and flexibility are priorities.
- Automotive and e-traction suppliers scaling from prototype to series production.
- Buyers of used or retooled equipment who want a certified pre-owned route.
A practical next step
Define your winding method (spindle, flyer or needle), wire diameter and target output per shift, then compare those against Marsilli's stated ranges. If your wire falls outside 0.02–2.5 mm or you need very high spindle counts, confirm feasibility directly; if you are earlier in development, the co-engineering service is the more relevant entry point than a production line quote.
Which winding method should I choose for my coil or motor project—spindle, flyer, or needle winding?
Choose based on the part geometry and how the wire must sit in the slot, not on a single "best" method. Marsilli frames its offer around three winding approaches: spindle winding and flyer winding for coils, and needle winding for open and closed stators in motor applications.
A practical way to decide
| Method | Best fit | Main trade-off |
|---|---|---|
| Spindle winding | Coils where the spindle carries the part and wire is laid precisely; suits a range of wire sizes and multi-spindle output | Part handling and spindle design constrain shape; less ideal for deep stator slots |
| Flyer winding | Coils needing fast, repeatable wire placement around a stationary or slowly moving core | Flyer mass and speed limits affect fine wire and delicate insulation |
| Needle winding | Motor stators, including open and closed slots, where wire must be placed into slots | Needle access and slot geometry limit fill factor and wire size; slower than flyer for simple coils |
Marsilli states its coil systems run from a single spindle up to 24 spindles, use wire from 0.02 to 2.5 mm, and reach up to 25,000 RPM. Those figures describe its product range, not a rule for every project; treat them as questions to raise with any supplier.
Concrete scenarios
- Small sensor or RFID coil, fine wire: spindle or flyer winding is the natural family; ask which handles your wire diameter without tension damage.
- Appliance motor stator with closed slots: needle winding is the usual starting point because the needle enters the slot directly.
- High-volume simple coil: multi-spindle spindle winding or flyer winding usually wins on cycle time; confirm changeover and tooling cost.
Next step
Write down wire diameter, coil or stator dimensions, slot type, annual volume and acceptable fill factor. Send that to two or three winding-system suppliers and ask each to recommend a method and explain the cycle-time and tooling implications. For broader context on motor manufacturing, IEEE publishes industry material, but your geometry and volume should drive the final choice.
Can Marsilli build a custom winding or assembly system tailored to my production requirements?
Yes. Marsilli presents itself as a builder of custom winding and assembly systems rather than only a catalogue supplier: the page emphasizes "precision, flexibility and customization" and lists a dedicated Co-Engineering Service, so the intended path for a non-standard requirement is a joint engineering project, not picking a stock machine.
What that means in practice
A tailored system is most relevant when your part or process falls outside standard envelopes—for example, a stator geometry, wire size, spindle count or output rate that off-the-shelf equipment does not cover. Marsilli's stated capability spans spindle and flyer winding for coils, needle winding on open and closed stators for motors, systems from a single spindle up to 24 spindles, wire from 0.02 to 2.5 mm, and speeds up to 25,000 RPM. These figures describe the range the company says it works within; whether your specific combination is feasible is exactly what a co-engineering discussion would establish.
The same page also points to adjacent services that matter for a custom build: refurbishment and retooling (useful if your requirements change after installation), training, and a customer platform. For a production engineer planning a new line, that combination—custom design plus later retooling—can reduce the risk of a system becoming obsolete when the product changes.
How to decide whether to pursue it
- Go custom if your winding method, wire range or assembly sequence is unusual, or if volumes justify a dedicated line.
- Start with co-engineering if you are unsure: bring drawings, wire specs, target cycle times and quality tolerances, and let the feasibility discussion define the scope.
- Check the industry fit: the page names automotive, appliances, electromechanical applications, RFID and consumer electronics, so a project in one of these areas aligns with existing experience.
A useful next step is to prepare a short requirement brief (part geometry, winding method, wire diameter, spindles needed, takt time, test/inspection needs) and request a co-engineering conversation through Marsilli. If you are still comparing suppliers, it also helps to look at other winding-equipment builders to benchmark which method each specializes in before committing to a design.
What does Marsilli's co-engineering service involve and when should I use it?
Marsilli's co-engineering service is a collaborative design offering for teams that need custom winding or assembly systems rather than a standard machine. Based on the site, it sits alongside refurbishment/retooling, training and the My.Marsilli platform as part of their service lineup, and it supports the company's stated emphasis on precision, flexibility and customization across motor and coil production. In practice, that means working with Marsilli's engineers to shape a system around your wire, coil or stator requirements—covering choices such as spindle versus flyer winding for coils, or needle winding on open and closed stators for motors—instead of adapting your process to an off-the-shelf unit.
When it makes sense to use it
- Your part is unusual. Very fine or heavy wire, tight tolerance demands, or a coil/stator geometry that standard machines handle poorly.
- You need a specific output target. The site describes systems from a single spindle up to 24 spindles at up to 25,000 RPM and wire sizes from 0.02 to 2.5 mm; co-engineering helps you land on the right point in that range.
- You're scaling from prototype to production. Co-engineering early can keep a pilot process compatible with the eventual production line.
- You operate in a demanding sector. Automotive, appliances, electromechanical, RFID and consumer electronics are the industries the site names, and each brings different volume and quality expectations.
When it may be overkill
If a catalog machine or certified pre-owned equipment already meets your specification, co-engineering adds time and cost without adding capability. Similarly, if your volumes are low and your part is conventional, a stand-alone standard system is usually the faster route.
How to decide
Start by documenting your wire size, target cycle time, spindle count and quality requirements, then ask Marsilli whether those fall inside an existing platform or need a co-engineered solution. For context on comparable custom-automation approaches, see Example—though for this specific service, the practical next step is to request a scoping discussion with Marsilli's team using your part drawings and volume forecast.
How do I get existing Marsilli equipment refurbished or retooled for a new product?
Use Marsilli's Refurbishment and ReTooling service, listed under Services on Marsilli. It is the direct route for adapting existing winding or assembly equipment to a new product, alongside their co-engineering and training offerings. The site also lists a My.Marsilli Platform and Certified pre-owned equipment, which suggests the company supports the lifecycle of installed machines, not only new builds.
What to prepare before contacting them
- Machine details: model, serial number, year of manufacture, and current configuration (for example, spindle count, winding method, and wire size range).
- Target product: coil or motor type, wire diameter, required turns, and output per shift. Their winding range spans 0.02–2.5 mm wire, 1–24 spindles, and up to 25,000 RPM, so these figures determine whether a retrofit is feasible or whether a different machine is needed.
- Gap analysis: what the current machine cannot do for the new part — tooling, motion axes, tension control, or handling.
- Constraints: floor space, utilities, acceptable downtime, and whether the line must stay in production during the work.
How to frame the request
State plainly that you have an installed Marsilli system and want it assessed for retooling to a new coil or motor. Ask for a technical review of the machine against the new part specification, a scope covering tooling changes and any control or software updates, and a plan for commissioning and operator training. Their training service is relevant here, since retooled machines often need new setup routines.
If the existing machine is a poor fit, ask in the same conversation about certified pre-owned equipment as an alternative to a full new system. That keeps the decision between retrofit, replacement, and a second machine in one discussion.
A useful first step: photograph the machine's nameplate and current tooling, and draft a one-page specification of the new part. Both make the initial assessment faster and reduce the risk of a scope that misses a constraint.
What training and support does the My.Marsilli platform provide for machine operators?
The page does not describe what training or operator support the My.Marsilli platform itself offers. My.Marsilli appears in the site navigation as a platform, and "Training" appears as a separate service item, but the supplied page content gives no detail on courses, formats, onboarding or in-platform help.
What can be inferred, and what cannot
- Platform support: Unspecified. Nothing on the page states whether My.Marsilli includes guided tutorials, remote diagnostics, documentation or operator dashboards.
- Training as a service: Listed alongside Co-Engineering, Refurbishment and ReTooling, and Certified pre-owned equipment, which suggests operator training is offered as a distinct service rather than only through the platform. Its content and delivery are not described.
- Remote support tools: The navigation lists TeamViewer QuickJoin and QuickSupport, which typically indicate remote assistance sessions. Their connection to My.Marsilli or to operator training is not stated.
Practical next step
If you are evaluating this for a production team, treat platform training as an open question rather than an assumed feature. When contacting Marsilli, ask specifically:
- Whether operator training is delivered in person, remotely, or inside My.Marsilli.
- What materials exist for new operators versus experienced staff during changeovers.
- How remote support is requested and whether it is tied to the platform.
- What happens to platform access and training records when a machine is refurbished or retooled.
