Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the Rexroth 3842547991:
- Rexroth 3842547992 – Higher torque variant in the same MTR-UE4x family
- Rexroth 3842547993 – Alternative speed rating, same frame size
- Rexroth 3842503516 – Earlier generation positioner motor, compatible mounting
- Rexroth 3842503517 – Equivalent positioner with updated encoder option
- Generic UE41 Frame Motors – Third-party equivalents with matching flange (IEC B14), verify shaft diameter and winding before substitution
Note: Always verify electrical ratings, shaft dimensions, and positioner interface before substituting. Contact Konmask for a verified compatibility check.
Why Choose the Original Model
- Factory-matched torque curve for Rexroth VarioFlow and MPS conveyor systems
- Integrated manual positioner (32.063.1281) ensures precise stop positioning without additional sensors
- Plug-and-play replacement — no parameter re-tuning required
- Bosch Rexroth quality assurance: tested to IEC 60034 standards
- Long service life with minimal maintenance in continuous-duty environments
Typical Applications
- Rexroth VarioFlow chain conveyor systems
- MPS (Modular Production Systems) assembly lines
- Workpiece carrier positioning and indexing
- Lean manufacturing and flexible assembly cells
- Automotive, electronics, and consumer goods production
System Compatibility
- Conveyor Systems: Rexroth VarioFlow S, VarioFlow Plus, MPS
- Control Systems: Compatible with standard 3-phase motor starters, VFDs (verify frequency/voltage), and Rexroth IndraControl PLCs
- Mounting: IEC B14 flange, standard UE41 frame — fits existing Rexroth motor brackets
- Power Supply: 3-phase, confirm local voltage (230V/400V/460V variants — specify when ordering)
Selection Guide
Use the following criteria to confirm this is the correct model for your application:
- ✅ Power requirement: 0.10 kW (100 W) — suitable for light-duty conveyor drives
- ✅ Speed: 1680 RPM — standard for VarioFlow belt/chain speed ratios
- ✅ Positioner type: Manual (32.063.1281) — no encoder feedback; for encoder versions, see 923-601-G4 variant
- ✅ Frame: MTR-UE41PP — confirm against your existing motor nameplate
- ⚠️ Voltage: Confirm 3-phase supply voltage before ordering
- ⚠️ If higher torque is needed: Consider 3842547992 or 3842547993

Replacement & Compatibility FAQ
Q: Can I use a generic three-phase motor to replace the 3842547991?
A: Mechanically possible if the frame (UE41), shaft diameter, and flange match. However, the integrated manual positioner (32.063.1281) is a Rexroth-specific component — a generic motor will not include it. Contact us for a verified equivalent.
Q: What is the difference between 923-600-G7 and 923-601-G4?
A: These are Rexroth internal variant codes. 923-600-G7 typically refers to the motor-only assembly; 923-601-G4 includes the positioner. The 3842547991 covers the combined unit. Confirm with your system documentation.
Q: Is this motor compatible with a VFD (variable frequency drive)?
A: The motor is rated for direct-on-line (DOL) start. VFD use is possible but verify insulation class and dV/dt rating. Consult Konmask for VFD-compatible variants.
Q: What is the lead time for the 3842547991?
A: In-stock units ship within 1–3 business days. For out-of-stock items, typical lead time is 2–4 weeks. Contact us for real-time availability.
Q: Do you provide a certificate of conformity?
A: Yes, available upon request for orders requiring documentation.
