For the broader 8LSA86 family, B&R specifies nominal speeds of approximately 1,500–2,000 rpm and a 240 × 240 mm flange. Exact speed, brake, shaft, encoder, and winding configuration should be confirmed from the complete nameplate before installation.
🏭 Operating Function
The motor converts electrical energy from a compatible servo drive into controlled mechanical rotation. In a complete B&R motion-control system, the servo drive regulates current and torque while feedback from the motor allows the controller to manage speed and position.
The 97 Nm nominal torque rating makes this motor suitable for applications requiring considerably more mechanical torque than smaller 8LSA frame sizes. B&R’s published data for a closely corresponding 8LSA86 configuration lists 97 Nm nominal torque, 115 Nm stall torque, 15.237 kW nominal power, and up to 3,600 rpm maximum speed. Exact values for the DB015D700-3 variant should be confirmed from its nameplate or motor documentation rather than assumed from another suffix.
🔩 Installation & Configuration
- Verify the complete motor designation before installation.
- Match the motor with the correct B&R servo drive and feedback configuration.
- Check the motor connector, power cable, feedback cable, and grounding arrangement.
- Confirm the flange dimensions and shaft interface before mechanical mounting.
- Make sure the motor is properly aligned with the driven machine to prevent excessive radial or axial loading.
- Check whether the specific motor has a holding brake before connecting the brake circuit.
- Configure the correct motor parameters in the servo-drive software.
- Confirm current, torque, speed, and feedback parameters before enabling the axis.
- Perform a low-speed test first and check rotation direction.
- During commissioning, monitor motor temperature, vibration, current, and drive alarms.
🛠️ Maintenance Tips
Keep the motor housing and connector area clean, particularly in environments with oil mist, dust, or metal particles.
The IP65 rating provides protection against dust ingress and water jets under the specified conditions, but it does not eliminate the need for correct cable and connector installation.
For a used motor, inspection should include the shaft, bearings, connectors, feedback system, insulation condition, and brake if fitted. Unusual bearing noise, excessive shaft play, abnormal temperature rise, or unstable feedback should be investigated before putting the motor into production.
When storing the motor, protect the connectors and shaft from moisture and mechanical impact. Avoid rotating or loading the shaft unnecessarily during transportation.
❓ Common Questions
Q: What type of motor is the 8LSA86.DB015D700-3?
It is a B&R 8LSA-series synchronous servo motor.
Q: What is the nominal torque?
The matching product data specifies 97 Nm nominal torque.
Q: What are the listed current values?
The product information specifies 29.8 A nominal input current and 35.3 A stall/output current.
Q: What is the protection rating?
The listed motor is IP65.
Q: What is the motor’s weight?
The referenced listing gives approximately 87.5 kg.
Q: Is this motor new?
No. The referenced listing identifies the unit as used.
Q: Can it be connected to any B&R servo drive?
No. The drive must support the motor’s electrical, feedback, current, torque, and configuration requirements. The exact motor data should be entered into the drive configuration.
Q: Does the motor include a brake?
The exact brake configuration should be verified from the motor nameplate. Do not assume a brake is installed simply because another 8LSA86 configuration has one.
Q: What is the flange size?
B&R lists the 8LSA86 family with a 240 × 240 mm flange.
Q: What should I verify before purchasing a replacement?
Match the complete model number, revision, torque rating, current rating, feedback type, connector arrangement, shaft dimensions, brake configuration, and mounting dimensions.

These belong to related B&R 8LS synchronous-motor families, but they should not be treated as direct substitutes without checking the complete electrical and mechanical specifications. B&R differentiates the 8LSA, 8LSC, 8LSO, and 8LSP families by cooling and connection arrangements.
📌 Application Summary
The B&R 8LSA86.DB015D700-3 is a large-frame synchronous servo motor intended for high-performance industrial motion systems. Its 97 Nm nominal torque, IP65 construction, and 240 × 240 mm mounting format make it suitable for machinery where high torque and controlled motion are important.
Typical applications can include machine tools, large automated production equipment, material-handling machinery, packaging systems, industrial positioning equipment, and other high-load servo axes.
For replacement projects, the safest approach is to match the complete motor identification rather than selecting a replacement based only on torque or frame size. The feedback device, shaft configuration, brake, connector arrangement, and compatible servo drive all need to match the existing machine.
