Description
Product Introduction
The B&R 8LSA35.R0030D200-0 is a compact, high-dynamic three-phase synchronous servo motor built for demanding industrial automation applications. Designed for direct integration with B&R ACOPOS servo drive families, this motor delivers precision velocity control and positioning across automated packaging machinery, CNC auxiliary axes, and robotic automation.
Unlike single-turn optical encoder models that struggle in heavy vibration environments, the 8LSA35.R0030D200-0 utilizes a rugged resolver feedback unit. Combined with an integrated 24VDC mechanical holding brake, it provides reliable holding power and absolute feedback stability on vertical Z-axes and high-duty positioning systems.

Application Scenarios & The “Trench” Experience
It was 3:45 AM during a graveyard shift when a vertical Cartesian pick-and-place gantry crashed on a primary packaging line. The old servo motor’s internal holding brake wore down and failed to engage during an emergency stop, sending a 15,000 end-effector plunging directly into the conveyor bed. The plant was losing 2,000 every ten minutes in unfulfilled shipments. We swapped in a fresh 8LSA35.R0030D200-0, hooked up the power and resolver leads, verified the 24V brake control line via the ACOPOS drive, and had the line running at 100% capacity by 4:30 AM.
- Vertical Axis Lifters & Z-Gantries – Elevator and vertical pick-and-place drives – Integrated spring-applied mechanical brake prevents payload drop during power loss.
- High-Vibration Material Handling – Stamping feeds and sorting systems – Analog resolver feedback handles heavy vibration where optical glass encoders break down.
- Packaging & Filling Machines – High-speed starwheels and capping heads – Compact Size 35 frame delivers high torque-to-inertia performance for rapid stop-and-go indexing.
Transparency SOP: Quality Assurance & Testing
We don’t just ship boxes; we test them on actual B&R ACOPOS test benches.
- Inbound Inspection: Physical check for housing damage, anti-counterfeit label validation, shaft runout verification, and connector pin integrity.
- Brake & Winding Diagnostics: Resistance testing across all phase windings (U, V, W), Megger insulation testing to ground, and 24VDC brake pull-in/release torque validation.
- Live Rig Testing: Mounted to a live ACOPOS drive rig to execute full-speed dynamic ramps up to 3,000 RPM.
- Resolver Alignment Verification: Feedback signal verification via Automation Studio to ensure perfect rotor-to-resolver phase angle alignment before locking motor parameters.
- Final QC & Anti-static Packaging: Degreasing, protective shaft cover installation, ESD bag wrapping, and custom foam packaging for drop-safe shipping.

The Veteran’s Tech Trap Guide (Crucial Value-Add)
- ⚠️ Measure the 24V Brake Supply Voltage: The integrated brake requires clean 24VDC (±10%) to fully disengage. If your drive cabinet power supply drops below 21.6V under load, the brake pads will drag while turning, burning out the motor within minutes.
- ❗ Resolver vs. EnDat Parameter Mismatches: This unit uses a Resolver (
R00code) rather than an EnDat digital encoder. You must select the resolver motor template inside B&R Automation Studio. If your drive was previously paired with anEAorEBseries motor, it will throw a feedback comm fault immediately upon power-up. - ⚠️ Smooth Shaft Clamping: The smooth shaft design relies entirely on friction couplings. Clean all rust inhibitors and oil off the motor shaft with solvent before torquing down your clamping hub, or the shaft will slip inside the coupling under peak load.
- ❗ Swivel Connector Orientation: Rotate the angled swivel connectors carefully by hand. Never force them with channel locks or pipe wrenches, or you will snap the internal resolver wiring harnesses inside the motor end-cap.
Frequently Asked Questions (FAQ for Conversion)
Q: Does the 8LSA35.R0030D200-0 support hot-swapping?
A: No. Disconnecting the motor cabling while the ACOPOS intermediate DC bus is energized will cause a massive arc flash across the pins, destroying the connectors and potentially blowing the drive’s output power modules. Always isolate power first.
Q: How does the drive know this motor has a brake attached?
A: Unlike EnDat models with automatic electronic nameplates, resolver motors require selecting the precise model number (8LSA35.R0030D200-0) in your Automation Studio hardware configuration so the drive correctly manages the 24V brake timing logic.
Q: Can I replace an 8LSA35 model that does NOT have a brake with this model?
A: Mechanically, yes—the mounting flange and shaft dimensions match. However, you will need to wire a 24VDC supply line to the brake connector pins; otherwise, the internal spring brake will remain locked and prevent the motor from turning.
Q: What warranty coverage do you provide on this surplus unit?
A: All New Surplus and Refurbished B&R motors include our comprehensive 12-month operational warranty starting from the date of delivery.
Q: Why buy surplus B&R motors instead of ordering straight from the factory?
A: Factory lead times for specialized B&R servo motors can stretch out to 12-20 weeks. Our surplus stock is available for immediate dispatch, letting you recover from catastrophic downtime in days rather than months, at a fraction of factory list price.
