ELAU SM140/30/120/P1/45/S1/B0 – High-Torque Synchronous AC Servo Motor | MaxxB4 Platform
Engineering Background
ELAU (now integrated into Schneider Electric’s Lexium motion portfolio) pioneered the MaxxB4 servo platform for demanding packaging, printing, and converting machinery. The SM140 frame-size series delivers high continuous torque in a compact footprint, purpose-built for multi-axis coordinated motion where cycle time and positional repeatability are non-negotiable.
Product Positioning
The SM140/30/120/P1/45/S1/B0 is a 140 mm flange, 30 Nm continuous-torque synchronous servo motor rated at 3000 RPM with a 120 V DC bus interface. It is the preferred drop-in replacement and upgrade path for OEM machine builders and MRO engineers maintaining ELAU-based production lines across food & beverage, pharmaceutical, and flexible packaging sectors.

Engineering Advantages
- High Torque Density: 30 Nm continuous in a 140 mm frame minimises machine footprint without sacrificing dynamic response.
- Absolute Multi-Turn Encoder (P1): Eliminates homing cycles after power-down, reducing machine restart time and improving OEE.
- IP65 Sealing: Withstands washdown, coolant mist, and airborne particulates common in food and pharmaceutical environments.
- Plug-and-Play MaxxB4 Compatibility: Direct electrical and mechanical compatibility with existing ELAU drive cabinets — no re-engineering required.
- Class F Insulation: Sustained operation in elevated ambient temperatures up to 40 °C without derating.
System Architecture & Signal Flow
The SM140/30/120/P1/45/S1/B0 interfaces with the ELAU MaxxB4 servo drive via a combined power and feedback cable. The P1 absolute encoder transmits position data over the Hiperface® protocol, providing the drive with real-time multi-turn absolute position without a separate battery backup unit. The 120 V DC bus feeds the motor power stage directly from the drive’s internal DC link, enabling fast regenerative braking and energy recovery during deceleration phases. Motion coordination is managed by the ELAU PacDrive controller (C400/C600) over SERCOS II or CANopen fieldbus, enabling deterministic multi-axis synchronisation at sub-millisecond cycle times.

Technical FAQ
Q: Is this motor compatible with the Schneider Electric Lexium 32 drive?
A: Yes. The SM140 series is electrically and mechanically compatible with Lexium 32 drives configured for ELAU motor parameters. Parameter file import may be required.
Q: Can I add a holding brake to this variant (B0)?
A: The B0 suffix indicates no integrated brake. If a holding brake is required for vertical axes, please enquire about the B1 variant (SM140/30/120/P1/45/S1/B1).
Q: What is the lead time for out-of-stock units?
A: Typical lead time for sourced units is 2–4 weeks. Contact us for urgent requirements — expedited sourcing is available.
Q: Do you provide a test report?
A: Yes. A pre-shipment test report covering winding resistance, insulation resistance, and encoder signal integrity is available upon request at no additional charge.
Q: What fieldbus protocols does this motor support?
A: The motor itself is protocol-agnostic. Fieldbus protocol (SERCOS II, CANopen, Profibus) is determined by the MaxxB4 / PacDrive controller configuration.
