Description
The B&R 8LSA35.DA030S000-3 is a high-performance, self-cooling three-phase AC synchronous servo motor developed by B&R Industrial Automation (an ABB company). Engineered specifically for highly dynamic motion control applications with high clock rates—such as packaging machinery, plastics processing, and robotics—this motor features a low rotor moment of inertia combined with a high torque-to-volume ratio. The motor relies on conventional air cooling (self-cooling, construction type A) and features an integrated EnDat inductive feedback encoder to support closed-loop servo drive operation via the ACOPOS drive family.

Mechanical Interface & Electrical Deployment Notes
Feedback System Constraints
The embedded DA 2.2 encoder utilizes the Heidenhain EnDat 2.2 protocol over an inductive 32-line single-turn scanning track. Because it is a single-turn encoder, absolute position tracking is lost once the motor shaft rotates past 360^\circ following a system power cycle.
Field Programming Note: Applications requiring absolute positioning across machine power cycles must execute a homing routine upon CPU boot, or save axis coordinates to non-volatile target PLC registers before system power down.
Single-Cable Solution (SCS) Connection
This motor utilizes the B&R Single-Cable Solution (SCS), which routes both the three-phase stator power lines (U, V, W), the grounding conductor (PE), and the digital EnDat encoder data channels inside a unified composite cable jacket via a physical size 1 swivel connector.
- Minimum Cable Cross-Section: 0.75 mm^2 copper conductors are recommended for nominal current loads.
- Shield Grounding: The braided shield of the single-cable assembly must make a 360^\circ metallic contact clamped directly to the metal panel ground plate near the servo drive to prevent high-frequency PWM switching transients from distorting encoder packets.
Shaft Installation Limits
The 8LSA35.DA030S000-3 features a smooth k6 cylindrical shaft measuring 14 mm \times 30 mm without a mechanical keyway or structural oil seal. Power transmission should be completed using friction-locking clamping elements or high-precision zero-backlash couplings. Do not apply impact forces (such as hammer strikes) to the shaft during installation; axial shocks can rupture internal encoder glass scales or dent the precision deep-groove ball bearings.
Frequently Asked Questions
Can this motor be utilized in gearbox assemblies with oil baths?
No, not directly in a flooded environment. Because this specific configuration variant lacks an integrated front oil seal, fluid from a gearbox or wet environment can migrate through the front bearing and flood the stator windings or encoder housing. For closed-coupling gearbox assemblies, verify that the gearbox possesses an isolated inputs shaft seal, or select a motor model variant that includes a factory shaft seal ring (IP65 option).
Which specific B&R drive series match this motor profile?
The electrical winding and feedback profiles are fully mapped into the motor component database within B&R Automation Studio software. The manufacturer explicitly recommends driving this hardware via the following units:
- ACOPOS series modules (e.g., 8Vxxxx.xx)
- ACOPOSmulti drive frameworks (8BVIxxxx blocks)
- ACOPOS P3 high-density multi-axis servo drives (8EIxxxx modules)
What does the “-3” suffix at the end of the material number signify?
The trailing -3 denotes a specific manufacturing generation or internal revision group used by B&R to manage internal bill-of-materials adjustments or electronic component obsolescence. It remains functionally identical and retrofits into systems designed for standard base level models, provided the host servo drive firmware matches contemporary software platform definitions.
