📐 Mechanical Characteristics
The 8LSA86 belongs to the larger-frame section of the B&R 8LSA motor family. B&R documentation identifies 8LSA85 and 8LSA86 motors with a 240 × 240 mm flange, approximately 230 mm centering diameter, and shaft sizes in the 42k6 / 55k6 range depending on the bearing configuration.
The motor is designed for flange mounting and uses a self-cooled construction. Before mechanical replacement, the mounting flange, shaft diameter, shaft length, coupling arrangement, and installation clearance should be compared with the original motor.
🔌 Electrical & Motion Integration
The B&R 8LSA family is intended for integration with B&R motion-control systems and servo drives. Proper drive-to-motor matching is essential because the motor’s feedback configuration, electrical characteristics, encoder information, and motor parameters must correspond with the controller configuration.
The motor’s embedded identification and feedback system should be considered during commissioning. When replacing an existing motor, record the original motor parameters before removal and verify the replacement motor’s identification and configuration in the motion-control system.
For a system retrofit, confirm:
- Motor model and complete order code
- Servo drive compatibility
- Feedback/encoder configuration
- Motor cable and connector type
- Rated current
- Motor parameter data
- Mechanical flange and shaft dimensions
- Rotation direction and machine reference position
🛠️ Installation & Maintenance
- Isolate the servo drive and machine power before installation.
- Verify the complete 8LSA86.DB015D700-3 identification.
- Inspect the motor housing, connectors, shaft, and mounting flange.
- Check the motor cable and connector for damage or contamination.
- Install the motor using the correct mounting hardware and alignment procedure.
- Verify shaft and coupling alignment before operation.
- Connect the motor and feedback cables according to the approved wiring configuration.
- Load or verify the correct motor parameters in the servo system.
- Perform a low-speed commissioning test.
- Check motor temperature, vibration, current, positioning accuracy, and abnormal noise during operation.
⚠️ Do not rotate or mechanically load the motor shaft during installation in a way that could damage the feedback system or coupling. Electrical installation and commissioning should be performed by qualified personnel.
🔍 Troubleshooting
Motor does not rotate:
Check servo-drive enable status, motor power connection, feedback connection, drive alarms, and motor parameter configuration.
Servo drive reports a feedback fault:
Inspect the encoder/feedback cable and connectors. Verify that the configured feedback type corresponds to the installed motor.
Excessive motor temperature:
Check operating load, acceleration/deceleration settings, duty cycle, cooling conditions, and motor current.
Abnormal vibration or noise:
Inspect mechanical alignment, coupling condition, bearings, mounting bolts, and machine load. Incorrect alignment can produce vibration even when the electrical system is operating normally.
Motor reaches overcurrent condition:
Verify the load torque, acceleration profile, motor parameters, cable connections, and servo-drive sizing.
IP65 protection is compromised:
Inspect seals, connectors, cable entries, and housing for damage. IP65 protection depends on proper installation and intact external components.
🧪 Inspection Checklist
For a used or surplus B&R 8LSA86.DB015D700-3, the following points should be checked before installation:
- Model number and complete order code
- E235396 marking
- Rev.C4 identification
- IP65 housing condition
- Motor connector condition
- Shaft and keyway condition
- Mounting flange condition
- Bearing noise or mechanical play
- Feedback operation
- Insulation condition
- Rotation test
- Servo-drive compatibility
The listed unit is identified as 1 piece. Actual cosmetic condition and operating condition should be verified against the physical motor before installation.
❓ Frequently Asked Questions

📦 Spare-Parts & Replacement Planning
The B&R 8LSA86 is a large-frame servo motor, so maintaining a compatible spare can significantly simplify maintenance for machines that depend on synchronized servo motion.
For critical production equipment, spare-parts planning should include the complete motor order code rather than relying only on the general 8LSA86 family designation. Feedback type, shaft configuration, connector arrangement, and revision can affect replacement compatibility.
For inventory management, record the motor’s complete nameplate information, machine position, associated servo drive, installation date, inspection history, and replacement status. This helps reduce downtime when a high-value motion-control component requires replacement.
