8LSA43.E1030C600-0 B&R

Product Dimensions：

The B&R 8LSA43.E1030C600-0 is a high-performance three-phase synchronous servo motor from the 8LSA series. It is designed for applications requiring high dynamic movement, precision, and a compact form factor. This self-cooling motor is a core component of the B&R motion control ecosystem, typically paired with ACOPOS servo drives to provide highly accurate position and speed control in industrial automation.

Product Parameters

The technical specifications of the 8LSA43 model highlight its power density and high-speed capabilities:

• Nominal Torque: 3.1 Nm

• Stall Torque (M0): 4.0 Nm

• Maximum Torque: Approximately 13 Nm to 15 Nm (dependent on drive configuration)

• Nominal Current: 1.9 A

• Stall Current (I0): 2.5 A

• Nominal Voltage: 400 V AC

• Number of Pole Pairs: 4 or 5 (standard for the 8LSA4 series)

• Flange Dimensions: 100 mm x 100 mm (Size 4)

• Centering Diameter: 95 mm (j6 fit)

• Degree of Protection: IP65 (protected against dust and water jets)

• Shaft End: Smooth shaft (standard for E-series configuration)

• Feedback System: Integrated EnDat or Resolver (specified by the "E1" code in the model number)

Product Advantages

The 8LSA series is engineered to provide several competitive benefits for machine builders:

• High Power Density: The compact design allows for significant torque output relative to its small physical size, making it ideal for machines with limited installation space.

• Dynamic Performance: Low rotor moment of inertia enables rapid acceleration and deceleration cycles, which is critical for high-throughput packaging and assembly lines.

• Embedded Parameter Chip: The motor contains an internal memory chip that stores all relevant motor parameters. When connected to a B&R ACOPOS drive, the system automatically identifies the motor, simplifying commissioning and preventing setup errors.

• Optimized Torque Ripple: The electromagnetic design is refined to minimize torque cogging, resulting in smooth rotation even at very low speeds.

• Robust Thermal Management: The self-cooling design utilizes the motor housing and mounting flange as a heat sink, maintaining stable operation in continuous S1 duty cycles.

Product Applications

This specific motor is widely used in sectors where speed and precision are paramount:

• Packaging Industry: Driving high-speed conveyor belts, wrapping machines, and pick-and-place units.

• Textile Machinery: Managing precise tension control and high-speed needle movements.

• Printing and Paper: Synchronizing rollers and cutters in printing presses to ensure accurate registration.

• Metalworking: Driving feed axes for CNC machinery and small-scale bending tools.

• Assembly Automation: Serving as the primary drive for rotary indexing tables and robotic handling arms.

Important Precautions

To ensure a long service life and safe operation, the following guidelines must be followed:

• Mechanical Stress: Under no circumstances should a hammer or blunt force be used when mounting couplings or pulleys to the shaft. Impact force can permanently damage the high-precision internal bearings and the encoder.

• Alignment Accuracy: Ensure that the motor shaft and the load are perfectly aligned. Radial or axial misalignment exceeding 0.03 mm can lead to vibration, premature bearing failure, and shaft breakage.

• Shaft Coating Removal: Before installation, remove the anti-rust coating from the shaft using alcohol or a suitable solvent. Do not use sandpaper or scrapers, as they will damage the precision surface finish.

• Thermal Environment: The motor is rated for an ambient temperature of -15°C to +40°C. If operated above 40°C, the nominal torque and current must be derated by 10% for every additional 10°C.

• Cable Handling: Use original B&R motor and encoder cables. Ensure the minimum bending radius is maintained to prevent internal wire fatigue and communication errors between the motor and drive.

• Grounding: The motor housing must be properly grounded to the machine frame to prevent electrical noise interference and ensure operator safety.
