Context and evolution of the PxG range
Since its inception, SEW‑EURODRIVE has positioned its planetary servo motors as a benchmark for precision and reliability. The PxG family, already renowned for its P5.G to P7.G performance levels, has progressively adapted to the growing demands of Industry 4.0.
The decision to introduce the PxG Economy series responds to clear demand: provide sufficient performance while mastering costs without compromising the quality that defines the group’s reputation.
Technical characteristics of the new P1.G, P2.G and P3.G models
- P1.G: light applications – maximum torque 10 Nm, speed up to 12 000 rpm.
- P2.G: intermediate loads – torque up to 25 Nm, speed up to 8 000 rpm.
- P3.G: demanding needs – torque up to 45 Nm, speed up to 6 000 rpm.
Each unit is equipped with a robust enclosure, IP65 protection and an advanced thermal management system, guaranteeing a lifespan exceeding 100 000 cycles without additional maintenance. The compact design allows seamless integration into existing drives and control systems.
Economic benefits and productivity gains
Reduced acquisition costs
The simplified architecture reduces material cost by 15% compared to the P5.G models. This savings translates directly into a lower final price for the end‑user.
- Lower purchase price.
- Reduced shipping weight.
- Simplified assembly.
Maintenance fees are also lowered thanks to component modularity, enabling quick replacements without prolonged line downtime.
Energy optimisation
The PxG Economy series incorporates an “economy” mode that automatically adjusts consumption based on load. Internal tests show an average 12% reduction in electrical consumption per cycle.
- Lower energy bills.
- Improved carbon footprint.
- Enhanced compliance with green‑energy regulations.
This results in substantial energy savings, especially relevant for large industrial plants subject to high utility bills.
Targeted industrial applications
Standard production line automation
- P1.G and P2.G: collaborative robotics, automated conveyance or pick‑and‑place systems. Their sufficient precision ensures flawless repeatability in demanding environments.
- P3.G: lightweight hydraulic presses and medium‑power CNC cutting machines where higher torque is required.
Integration into IoT systems
Thanks to their standardised interface, these servo motors can be integrated into OPC UA or Modbus TCP networks, facilitating data collection and predictive analytics for continuous optimisation.
- Real‑time performance visibility.
- Reduced unplanned downtime.
- Seamless integration with existing MES systems.
Comparison with the high‑precision PxG P5.G to P7.G range
While the P5.G to P7.G models offer a precision of 0.01 µm and torques up to 100 Nm, the economy series focuses on a cost‑performance compromise. Users who do not need extreme repeatability can opt for PxG Economy without sacrificing reliability.
The choice will therefore depend on load profile, precision requirements and available budget. SEW‑EURODRIVE offers an online tool to simulate total costs over a unit’s lifespan.
Future outlook and upcoming innovations
- Expansion of the PxG Economy line with advanced connectivity options, including native MQTT support for industrial IoT.
- Thermal efficiency improvements targeting an additional 5% reduction in energy consumption.
- Development of low acoustic signature variants to meet growing demands for quiet work environments.

“Since we replaced our old servo motors with PxG Economy models, our energy consumption has dropped by 10% and downtime has fallen from 3 h to under 30 min.” – Automation Engineer, Industry X
Installation guidelines and integration checklist
For a smooth deployment of the PxG Economy series, SEW‑EURODRIVE recommends following a structured installation procedure. Begin by verifying that your existing drive cabinet can accommodate the motor’s dimensions and weight. The compact design typically requires less than 10% additional space compared to the P5.G models.
- Confirm power supply compatibility (400 V, 50/60 Hz) and ensure proper grounding according to IEC‑60364.
- Check that the motor’s mounting flange aligns with your machine’s mechanical interface; use the supplied flange adapters if necessary.
- Install the supplied thermal sensor and connect it to the drive controller for real‑time temperature monitoring.
- Program the “economy” mode in the drive firmware, setting load thresholds that match your application profile.
Once installed, perform a quick calibration routine: run the motor at 50% load, record speed and torque data, then adjust the encoder resolution if needed. This ensures optimal performance across all operating conditions.
Case study: Energy savings in a packaging plant
A mid‑size packaging facility replaced its legacy servo motors with the PxG Economy P2.G model on 12 conveyor lines. Over six months, the plant recorded an average energy reduction of 11% and cut maintenance visits by 30%. The modular design allowed quick swaps during scheduled downtime, minimizing production loss.
These results underscore how the PxG Economy series not only meets performance demands but also delivers tangible ROI through lower operating costs and enhanced reliability.
