EU Machinery Regulation 2023/1230: Planetary Gear Motor Compliance Guide

The European Union is overhauling its machinery safety framework. If you are an OEM importing Autonomous Mobile Robots (AMRs), smart access gates, or heavy-duty industrial automation into the EU, the clock is ticking.

On January 20, 2027, the long-standing Machinery Directive 2006/42/EC will be completely repealed and replaced by the Machinery Regulation (EU) 2023/1230. Unlike a "Directive," which requires individual EU member states to pass their own national laws, a "Regulation" is a binding legislative act. It applies immediately and uniformly across all 27 EU member states.

For procurement managers and engineers sourcing planetary gear motors, this is not just a paperwork update. The new regulation fundamentally changes how we handle integrated sensors, digital documentation, cybersecurity, and the classification of assemblies. If your gear motor supplier is still relying on outdated CE declarations from 2018, your 2027 AGV product launch could face a hard stop at EU customs.

Here is the gritty, no-nonsense breakdown of what changes under (EU) 2023/1230, how it impacts your planetary gear motor sourcing, and the exact steps you need to take to protect your supply chain.

Published: June 24, 2026. Applicability: OEM teams placing machinery or partly completed machinery on the EU market from January 20, 2027. Limit: This is an engineering and procurement guide, not legal advice; confirm final CE strategy with your notified body, EU importer, or compliance counsel.

1. Scope: Is Your Gear Motor "Machinery"?

The most common point of confusion between mechanical engineers and compliance officers is whether a gear motor assembly is considered a standalone machine, a component, or something in between.

The Machinery Regulation distinguishes between "Machinery," "Partly Completed Machinery" (PCM), and excluded components. Understanding this boundary is critical because it dictates exactly what documentation your motor supplier must provide.

The Low Voltage Directive (LVD) Exclusion

Under Article 1(2)(p)(vi) of the new Regulation, ordinary electric motors are explicitly excluded from the scope of the Machinery Regulation if they fall under the Low Voltage Directive (LVD) 2014/35/EU.

If you are buying a bare, standard BLDC or brushed DC motor without a gearbox, no complex control electronics, and no specific application interface, it generally falls under the LVD. The supplier provides an EU Declaration of Conformity to the LVD, affixes a CE mark, and you are done.

The "Partly Completed Machinery" (PCM) Reality

However, an OEM rarely buys a bare motor. You are buying a Planetary Gear Motor—an assembly consisting of a motor, a multi-stage planetary gearbox, an output shaft engineered for a specific radial load, and often an integrated magnetic encoder or holding brake.

When this assembly cannot perform its specific application independently (because it needs to be bolted to an AGV chassis and connected to a motor controller) but is intended to be incorporated into another machine, it is classified as Partly Completed Machinery (PCM). If the same project also needs ratio, wheel-speed, and torque-reserve decisions, start with our AGV planetary gear ratio selection method before freezing the compliance file.

This triggers a completely different compliance track under (EU) 2023/1230.

A Partly Completed Machine (PCM) does not get a CE mark to show compliance with the Machinery Regulation. Instead, your gear motor supplier must provide an EU Declaration of Incorporation alongside detailed assembly instructions showing you how to safely integrate the motor without violating the Essential Health and Safety Requirements (EHSRs).

2. Comparing the Old Directive vs. the New Regulation

The shift from 2006/42/EC to 2023/1230 isn't just about updating a document title. The European Commission has modernized the rules to account for robotics, Artificial Intelligence, IoT connectivity, and sustainability.

If you are an OEM, here are the critical procurement differences you need to monitor:

3. The Cybersecurity Mandate for Smart Motors

Historically, mechanical gear motors were dumb chunks of metal, copper, and magnets. The safety risks were purely physical: crushing, shearing, or electrical shock.

Today, many premium OEM planetary gear motors come with integrated smart controllers, dual-channel absolute encoders, and CANopen/EtherCAT interfaces. They report temperature, vibration, and torque data back to the central AGV PLC.

Under the new Regulation, software and cybersecurity are safety features.

If a hacker can access the AGV network and override the planetary gear motor's braking torque limits, causing the vehicle to crash, the machinery is deemed unsafe. Suppliers of smart motor assemblies (treated as safety components or PCMs) must now demonstrate that the control systems are designed to withstand both accidental interference and intentional cyberattacks.

What you need to do: If your gear motor has integrated logic or communication protocols, demand to see the supplier's cybersecurity risk assessment. Ask how firmware updates are authenticated and secured.

For the commercial file, add these cybersecurity and firmware-update questions directly to your planetary gear motor RFQ template so they are evaluated before sampling, not after tooling has started.

4. The "Substantial Modification" Trap for Maintenance Teams

Article 18 of the new Regulation introduces a strict legal definition for "Substantial Modification". This is crucial for OEMs who offer aftermarket upgrades, or operators who retrofit existing fleets.

If you replace a failing 30Nm gear motor with an identical 30Nm gear motor, this is a repair. It does not trigger new compliance requirements.

However, if you upgrade a warehouse AGV by swapping its old brushed DC motors for higher-speed, high-torque BLDC planetary gear motors to increase throughput, you have structurally changed the machine's performance and kinetic energy. Under 2023/1230, the person carrying out this modification is now considered the manufacturer of a new machine. You must conduct a new risk assessment, draw up new technical documentation, and affix a new CE mark.

5. OEM Engineering & Procurement Audit Checklist

To ensure a smooth transition before the January 2027 deadline, your procurement and engineering teams should run this exact checklist against your current and prospective gear motor suppliers:

• [ ] PCM Classification Check: Has the supplier accurately classified the geared motor assembly as "Partly Completed Machinery" rather than improperly blanketing it under the LVD?
• [ ] Annex V Preparation: Can the supplier provide a draft "EU Declaration of Incorporation" formatted to Annex V, Part B of the new Regulation (instead of the old Annex II)?
• [ ] Digital Assembly Instructions: Has the supplier established a secure, accessible web portal to host the mandatory digital assembly instructions? Are the links permanent?
• [ ] EHSR Mapping: Has the supplier explicitly mapped out which Essential Health and Safety Requirements (from the new Annex III) their gear motor fulfills, and which ones are left to you (the integrator) to resolve?
• [ ] Cybersecurity Assessment (For Smart Motors): If the gear motor includes embedded software or network interfaces, has the supplier provided a cyber-risk mitigation report?
• [ ] Technical File Availability: Does the supplier have a clear policy for how they will provide the Annex IV technical documentation to EU market surveillance authorities upon a reasoned request?

Use this audit together with your incoming and pre-shipment QC checklist so documentation review, label review, functional testing, and shipment release are controlled in one supplier file.

7. Frequently Asked Questions (FAQ)

When does the new EU Machinery Regulation 2023/1230 take effect?

The regulation was published in June 2023, but it fully replaces the old Machinery Directive 2006/42/EC on January 20, 2027. After this date, you cannot place machinery on the EU market using the old directive's declarations.

Why doesn't my planetary gear motor have a CE Mark?

If your gear motor is classified as Partly Completed Machinery (PCM) under the Machinery Regulation, it is legally prohibited from bearing a CE mark for the Machinery Regulation. The CE mark is applied to the final completed machine (e.g., the fully assembled AGV). The motor will instead come with an EU Declaration of Incorporation.

Can assembly instructions be entirely digital now?

Yes. Under the new regulation, digital documentation is the default. However, if an end-user specifically requests a paper copy at the time of purchase, the manufacturer must provide it free of charge within one month.

What if I buy a motor from outside the EU (e.g., from China)?

The regulation applies to any machinery or partly completed machinery placed on the EU market, regardless of where it was manufactured. Your non-EU supplier must still draft the EU Declaration of Incorporation, compile the technical file, and you (or the EU importer) assume the responsibility for ensuring the documentation is compliant.
