Description
B&R 8LS46.R0045D000-0 – High‑precision Servo Motor for Fast, Repeatable Motion on OEM Machinery
The 8LS46.R0045D000-0 is a B&R 8LS series synchronous servo motor, typically paired with ACOPOS servo drives for tight position and speed control. From my experience, the “8LS46” frame fits nicely into compact machines—pick‑and‑place axes, format adjustments, small indexing tables—where smooth torque delivery and clean cabling matter. You might notice the “R” build code often indicates resolver feedback, which many maintenance teams prefer for robustness in electrically noisy cabinets.

Key Features
- Synchronous servo design – Low cogging and high dynamics for accurate positioning and smooth speed control.
- Resolver feedback build (R‑code) – Typically chosen for rugged duty and reliable startup homing in noisy environments.
- Compact “46” frame – A good fit for tight machine spaces with short axial length options.
- ACOPOS drive compatibility – Plug‑and‑run with B&R ACOPOS drives; commissioning is usually quick when replacing like‑for‑like.
- Industrial protection – When mated with the correct connectors and gaskets, the motor housing is well suited for dusty plant floors.
- Clean installation – Separate power and feedback connectors simplify routing and service checks.
Technical Specifications
| Brand / Model | B&R – 8LS46.R0045D000-0 (8LS series synchronous servo motor) |
| HS Code | 850152 (AC multi‑phase motors > 750 W; common classification for servo motors) |
| Power/Drive Interface | Powered by ACOPOS servo drive 3‑phase PWM output; not connected directly to mains |
| Feedback System | Resolver feedback (R build), compatible with B&R drives that support resolver inputs |
| Operating Temperature | Typically 0…40 °C ambient for rated data (derating may apply above this range) |
| Signal/Power Connections | Separate power (3‑phase + PE) and feedback connectors; optional brake leads depending on sub‑variant |
| Installation Method | Flange mounting (IEC style) with keyed shaft; horizontal or vertical orientation as per application |
Application Fields
Typical duties where this motor performs well:
- Packaging and labeling: high‑speed infeed, rotary knives, registration rolls
- Electronics assembly: pick‑and‑place axes and small gantries
- Food & beverage: format change mechanisms, feeders, augers
- Textile/printing: tension control and precise web handling
Advantages & Value
- Reliability: Resolver builds typically tolerate electrical noise and temperature swings better in many cases.
- Compatibility: Drop‑in with existing ACOPOS axis hardware—no rewiring headaches when replacing like‑for‑like.
- Lifecycle cost: Stable spares strategy; keeping motor and drive from the same vendor simplifies diagnostics and tuning.
- Support: We can perform spin‑test and insulation checks and share results before shipment.
Installation & Maintenance
- Mounting & alignment: Use the flange pilot for centering; check shaft/runout and coupling alignment to avoid bearing load.
- Wiring: Route power and feedback separately; maintain minimum bend radius; bond PE to the motor body.
- Noise practices: Keep motor and drive cables away from sensitive analog lines; use shielded motor cable with 360° grounding where possible.
- Brake (if fitted): Supply 24 VDC per the nameplate and release sequence recommended by the drive.
- Routine care: Quarterly visual inspection for connector integrity, gasket condition, and dust; check bearings for abnormal noise during PMs.
- Safety: Lockout the drive DC bus; wait for DC link discharge before disconnecting cables; follow ESD precautions on feedback connectors.
Quality & Certifications
- Certifications: CE; UL/cUL for industrial machinery (typical for B&R 8LS series); RoHS compliant by series.
- Manufacturing quality: Built under ISO 9001 quality systems.
- Warranty: 365‑day warranty from shipment date.
Share your drive type (ACOPOS model), required feedback option, and brake preference, and we’ll verify that 8LS46.R0045D000-0 matches your axis data and provide a quick spin‑test/insulation report before dispatch.
