Description
ELAU SH140/30120/0/1/00/00/00/00/00 — PacDrive SH Servo Motor
Product Introduction
Large packaging and machine-tool axes can expose weaknesses in a motion system quickly: insufficient torque, incorrect encoder configuration, or a mechanically incompatible shaft can stop commissioning even when the motor itself is electrically sound. The ELAU SH140/30120/0/1/00/00/00/00/00 is a 140 mm-frame permanent-magnet synchronous servo motor from the PacDrive SH family, configured for a keyed shaft, singleturn absolute feedback, and no holding brake. The documented Schneider configuration reference is SH31401P11A2000.
This configuration provides approximately 11.1 Nm standstill torque, a documented 3,000 rpm rated operating point, and approximately 2.89 kW rated output. The complete option code matters: other SH140/30120 versions use multiturn feedback, holding brakes, different protection configurations, or different shaft arrangements. For a brownfield PacDrive replacement, match the complete code and motor nameplate rather than ordering by the SH140 frame designation alone.

Because option codes alter the protection and feedback configuration, the physical nameplate should take precedence where it differs from generic family data.
Major Features and Engineering Advantages
1. 140 mm PacDrive SH motor platform
The /30120 configuration belongs to the larger 140 mm-frame portion of the ELAU PacDrive SH motor family. Its torque level is suited to machine axes requiring substantially more mechanical output than smaller SH frame variants. The 11.1 Nm standstill torque and 3,000 rpm rated point make the motor appropriate for demanding cyclic motion applications.

2. Keyed shaft configuration
The /1/ configuration identifies the keyed-shaft version. This is an important mechanical interface detail. A smooth-shaft or differently configured motor may have essentially the same electrical envelope while still being unsuitable for the existing coupling or pulley arrangement.
3. Singleturn absolute feedback
This exact configuration uses SinCos SKS36 singleturn absolute feedback. That feedback selection must match the PacDrive drive/controller configuration. It should not be assumed that a visually identical fitted with multiturn feedback can be substituted without configuration changes. Schneider’s product records show separate variants for singleturn and multiturn feedback.
4. No holding brake
The exact configuration is specified without a holding brake. This is particularly important on vertical or gravity-loaded axes. A no-brake motor should not be substituted for a brake-equipped version simply because the torque and frame dimensions appear similar.
Schneider’s own product records demonstrate that otherwise similar /30120 configurations are available with and without brakes.
5. 4,000 rpm maximum mechanical speed
The motor is documented with a maximum mechanical speed of approximately 4,000 rpm. Actual permitted operating speed remains dependent on the drive, load, feedback system, machine mechanics, and application profile.
6. Class F insulation and PTC thermal monitoring
The motor uses Class F insulation and incorporates a three-core PTC thermistor for thermal monitoring. This gives the drive/control system a direct means of supervising motor temperature rather than relying solely on calculated load conditions.
Application Scenarios & Pain Points
Packaging machinery
PacDrive SH motors are associated with coordinated motion applications such as packaging machinery. The combination of absolute feedback and relatively high torque makes this configuration suitable for mechanically demanding synchronized axes.
Conveyor and feed mechanisms
The 11.1 Nm standstill torque provides useful capacity for feed rollers, transfer mechanisms, and other cyclic machine axes. Actual sizing still needs to account for acceleration torque, reflected inertia, gearbox ratio, duty cycle, and peak load.
Cutting and processing axes
Applications involving cutters, forming mechanisms, or material-handling axes can benefit from the motor’s 3,000 rpm rated operating point and absolute feedback.
Brownfield PacDrive replacement
This is where exact configuration matching becomes critical. The same /30120 family includes keyed and smooth shafts, singleturn and multiturn feedback, and brake/no-brake variants. Schneider’s product records show different replacement references for these configurations.

Engineer’s Guide — Field Pitfalls to Avoid
1. Do not order only by “.”
The family contains multiple shaft, encoder, brake, and environmental configurations. The complete code is required for a reliable replacement match.
2. Check the feedback type before connecting the motor.
This exact configuration uses SinCos SKS36 singleturn feedback. A multiturn or different encoder configuration may require a different drive setup and cannot be treated as an interchangeable motor.
3. Verify the brake requirement mechanically.
This motor is without a holding brake. For vertical axes or loads that can move when torque is removed, verify the machine’s external holding arrangement before installation.
4. Match the keyed shaft.
The shaft interface is part of the machine coupling. A smooth-shaft replacement can require mechanical changes even if its electrical ratings are similar.
5. Check the drive current and overload capability.
The motor’s approximately 6.8 A rated current and 20.8 A peak current should be evaluated against the actual PacDrive drive’s continuous and peak output capability. Motor sizing should include acceleration and duty-cycle calculations, not just nominal kW.
6. Verify the protection configuration.
Nearby codes can carry different IP ratings. Schneider’s records show, for example, singleturn/no-brake variants with different protection configurations and separate replacement references.
7. Do not assume a newer SH3 replacement is plug-and-play.
Schneider lists replacement SH3 references for legacy configurations, but a replacement can still require checking mounting, feedback, connector arrangement, drive configuration, and application software. Treat Schneider’s listed replacement as a starting point for engineering verification, not an automatic field substitution.
FAQ
What is ELAU /30120/0/1/00/00/00/00/00?

What is the torque rating?
The motor has a documented 11.1 Nm standstill torque and approximately 9.2 Nm rated torque, with approximately 27 Nm peak torque in the referenced configuration data.
What is the rated speed?
The documented rated operating point is 3,000 rpm, with a maximum mechanical speed of approximately 4,000 rpm.
Does this motor have a brake?
No. The exact /00/00/00/00/00 configuration is the no-brake version. This must not be confused with variants containing a brake, such as configurations mapped to SH31401P11F2000.
What encoder or feedback does it use?
The exact configuration is associated with SinCos SKS36 singleturn absolute feedback. Other /30120 variants use SKM36 multiturn feedback, so the complete ordering code matters.
What is the Schneider Electric replacement reference?
The exact configuration is mapped to SH31401P11A2000. Schneider also provides replacement references for several other /30120 configurations, but those should not be assumed interchangeable with this exact no-brake/singleturn configuration.
What should I verify before purchasing a replacement?
Verify the complete /30120/0/1/00/00/00/00/00 code, SH31401P11A2000 reference, keyed shaft, singleturn SKS36 feedback, absence of a holding brake, connector orientation, protection configuration, motor nameplate, and actual inventory condition. If replacing an installed motor, also verify the PacDrive drive model and configured motor/encoder data before commissioning.
