B&R 8LSA45.R0030D000-0 Servo Motor 3000 RPM 1.9kW

Description

Product Introduction & Engineering Value

The B&R 8LSA45.R0030D000-0 is a 8LS series synchronous servo motor designed for medium-duty precision motion applications. It provides a 3000 rpm rated speed, approximately 6.16 Nm rated torque, and resolver feedback for closed-loop operation with compatible B&R ACOPOS motion controllers.

In production equipment, servo motor replacement is rarely just a mechanical swap. Engineers must confirm torque requirements, feedback compatibility, drive parameters, and shaft configuration. A correct 8LSA45.R0030D000-0 replacement helps preserve existing machine tuning and avoids unnecessary axis redesign.

Technical Specifications

Field Application & The “Trench” Experience

A high-speed converting machine used multiple servo axes for synchronized roller positioning. After several years of operation, one axis began producing intermittent position deviation alarms during acceleration.

The first troubleshooting step focused on mechanical alignment. The coupling, gearbox, and driven roller were inspected, but no excessive wear was found.

Drive diagnostics showed unstable resolver feedback from the motor side. The maintenance team replaced the failed unit with a tested B&R 8LSA45.R0030D000-0, restored the axis parameters, and verified motor identification through the ACOPOS system.

The machine returned to production without changing the mechanical assembly.

The field lesson: when a servo axis loses repeatability, feedback integrity should be checked alongside mechanical components.

Typical application scenarios:

• Printing and web-handling tension control systems
• Packaging machine indexing axes
• Material feeding and positioning equipment
• Precision assembly automation
• Machine tool auxiliary axes

The Veteran’s Tech Trap Guide

⚠️ Trap #1: Replacing Resolver Feedback With Encoder Feedback

The 8LSA45.R0030D000-0 uses resolver feedback.

Before replacement, verify:

• Feedback interface
• ACOPOS drive compatibility
• Motor parameter set

A motor may fit mechanically but fail commissioning if feedback hardware differs.

⚠️ Trap #2: Ignoring Motor Tuning Data

Servo systems depend on stored axis parameters.

Back up:

• Motor identification values
• Velocity loop settings
• Position loop parameters
• Travel limits

PRO TIP: Save the original axis configuration before removing the failed motor.

⚠️ Trap #3: Overlooking Shaft and Mounting Details

Always compare:

• Flange dimensions
• Shaft diameter
• Connector orientation
• Mounting position

Emergency replacements often fail because mechanical details were not checked before shipment.
