B&R 8LSA55.EB030D200-1 Synchronous Servo Motor 3000 RPM

Description

Product Introduction

The B&R 8LSA55.EB030D200-1 is a heavy-duty, high-torque three-phase AC synchronous servo motor designed for high-precision motion applications. Engineered to integrate natively with B&R ACOPOS servo drives, this Size 55 motor provides continuous, smooth torque output across heavy-duty automated packaging machinery, multi-axis metal forming equipment, high-speed gantries, and plastic blow-molding equipment.

Unlike basic optical or single-turn resolver units, the 8LSA55.EB030D200-1 comes equipped with an EnDat multi-turn absolute encoder (EB code) and an integrated 24VDC mechanical holding brake (D200 code). The multi-turn encoder retains absolute positional data across power cycles without requiring homing routines, while the factory brake ensures vertical payload safety during emergency stop events.

Key Technical Specifications

Application Scenarios & The “Trench” Experience

It’s 3:10 AM during a peak production run on a critical automotive stamping transfer system. A sudden utility power blink causes the plant to drop off the grid. When power restores, the main vertical lifter axis loses its position homing routine because the old single-turn motor’s battery backup failed. Worse yet, the mechanical brake slipped, causing a heavy die set to descend into a half-indexed transfer tray. The tool-and-die team is looking at 12 hours of downtime. We replace the damaged motor with an 8LSA55.EB030D200-1. Thanks to its multi-turn absolute EnDat encoder, the ACOPOS drive reads the exact physical position immediately upon boot-up—zero homing sequence required. The plant is back up and making parts within an hour.

• Heavy-Duty Vertical Gantries & Elevators – High-load Z-axes – Integrated 24V spring-applied brake holds heavy mechanical loads securely during power outages or E-stops.
• Automated Automotive Transfer Systems – High-speed stamping & assembly feeds – Absolute multi-turn EnDat feedback eliminates time-consuming machine homing cycles after grid dropouts.
• Plastic Blow Molding & Extrusion – Mold clamping & carriage movement – High stall torque (~11 Nm) handles heavy continuous clamping forces without thermal shutdown.

Transparency SOP: Quality Assurance & Testing

We don’t just ship boxes; we test them on actual B&R ACOPOS test benches before they ever reach your facility.

1. Inbound Inspection: Physical housing verification, anti-counterfeit tag check, shaft runout measurement, and connector header inspection.
2. Electrical & Brake Parameter Checks: Insulation resistance (Megger) checks across phase U, V, and W windings to earth ground; 24VDC brake pull-in/release torque validation.
3. Live Rig Testing: Mounted to an ACOPOS drive test bench to run automated dynamic velocity ramps up to the full 3,000 RPM rating.
4. EnDat Multi-Turn Diagnostics: Communication verification via B&R Automation Studio to confirm absolute position retention across power cycling and verify electronic nameplate data readout.
5. Final QC & Anti-static Packaging: Degreasing, protective shaft sleeve installation, heavy ESD bag sealing, and custom foam packaging for safe transit.

The Veteran’s Tech Trap Guide (Crucial Value-Add)

• ⚠️ Verify the 24V Brake Voltage Drop: The integrated spring-applied brake requires a full 24VDC (±10%) signal to disengage completely. If long cable runs cause a voltage drop down to 21V at the connector, the brake pads will partially drag against the rotor, overheating and cooking the motor windings within 30 minutes.
• ❗ EnDat Multi-Turn (EB) vs. Single-Turn (EA) Software Config: This motor contains an EnDat Multi-Turn encoder. While the ACOPOS drive reads the electronic nameplate automatically, ensure your Automation Studio project configuration matches the multi-turn parameter setup if you are swapping out an older single-turn (EA) or resolver (R00) motor.
• ⚠️ Smooth Shaft Clamping Hub Torque: The standard smooth shaft relies on friction-fit couplings. Thoroughly clean off all factory anti-corrosion grease with solvent prior to installation. Torque clamping screws evenly to spec—if the coupling slips, you will score the precision-ground shaft.
• ❗ Careful Connector Swiveling: The angled connectors swivel for easy cable routing, but they have built-in rotation stops. Never force them with channel locks or pipe wrenches, or you will snap the internal encoder ribbon cables inside the end-bell enclosure.

Frequently Asked Questions (FAQ for Conversion)

Q: Is the B&R 8LSA55.EB030D200-1 hot-swappable?

A: No. Unplugging or plugging in the motor power cabling while the ACOPOS intermediate DC bus is charged (560 VDC) will generate a severe arc flash across the connector pins. This destroys the connectors and will ruin the output power stage in the drive. Always isolate main power first.

Q: Does this motor require manual parameter entry in Automation Studio?

A: No. Because it utilizes an EnDat digital encoder (EB), the ACOPOS drive automatically reads the internal electronic nameplate parameters (current ratings, torque constants, pole count) as soon as the drive powers up.

Q: Can I use this brake-equipped motor to replace a model that didn’t have a brake (D000)?

A: Mechanically, yes—the mounting flange and shaft dimensions match. However, you must supply a dedicated 24VDC control line to the brake connector pins. If left unpowered, the spring brake will remain locked and prevent the motor from turning.

Q: What warranty coverage is included with this motor?

A: All New Surplus and Refurbished B&R motors come backed by our full 12-month operational replacement warranty from the date of delivery.

Q: Why buy New Surplus B&R components over direct factory ordering?

A: Factory lead times for B&R Size 55 servo motors can extend anywhere from 12 to 24 weeks. Surplus sourcing gives you authentic, bench-tested OEM hardware shipped immediately, cutting critical plant downtime from months to days.
