B&R 8LSA44.EB030D1000: Synchronous Servo Motor

This part number specifies a particular configuration within B&R’s 8LS synchronous motor series. These motors are renowned for their compact design, high power density, and excellent dynamic performance.

Key Specifications and Features:

• Type: Synchronous Servo Motor
• Manufacturer: B&R Automation (now part of ABB)
• Series: 8LS
• Frame Size/Design: The “44” in “8LSA44” indicates a specific frame size or motor design within the 8LS series. This frame has a centering diameter of 95 mm for mounting.
• Rated Speed: 3000 RPM (revolutions per minute).
• Stall Torque: Approximately 6.000 Nm (Newton-meters).
• Nominal Torque: Around 4.6 Nm.
• Nominal Current: Typically in the range of 2.8 to 3.7 Amps.
• Voltage: Operates at 400 V.
• Shaft: Smooth shaft, meaning it does not have a keyway or spline.
• Connectors: Features angled swivel connectors, providing flexibility for cable routing.
• Brake: The “EB” in the part number indicates it does not include a holding brake.
• Protection Class: IP64, indicating it is protected against dust ingress and splashing water from any direction.
• Cooling: Self-cooling (construction type A), meaning it relies on natural convection or its own rotating parts for cooling, without an external fan.
• Pole Pairs: Typically 5 pole pairs.
• Feedback System: The “D1000” (or similar Dxxx code) usually refers to the encoder or feedback system. While the exact resolution for D1000 isn’t explicitly stated in the provided snippets, 8LS motors often come with high-resolution incremental or absolute encoders (e.g., 19-bit or 25-bit encoders for precise positioning).
• Embedded Parameter Chip: B&R 8LS motors typically feature an embedded parameter chip that stores all relevant mechanical and electrical information. This allows the servo drive to automatically identify the motor and configure itself for optimal control without manual settings.

Decoding the Part Number (General 8LS Structure):

• 8LS: Denotes the 8LS Synchronous Motor series.
• A44: Refers to the motor type and specific mechanical dimensions/characteristics (e.g., self-cooled, flange-mounted, frame size).
• EB: Indicates the connection type and absence of a brake (angled swivel connectors, no brake).
• 030: Relates to the nominal speed (e.g., 3000 rpm).
• D1000: Specifies the integrated feedback system (encoder type and resolution).
• The final digit (e.g., “-3” if it were 8LSA44.EB030D1000-3) often indicates a version or specific variant, but in the provided part number “D1000” is the end.

Typical Applications:

B&R 8LS synchronous servo motors are widely used in various industrial automation applications requiring precise, dynamic, and reliable motion control. These include:

• Packaging Machinery: For precise positioning, cutting, sealing, and handling.
• Machine Tools: In applications where accurate linear or rotary movements are critical, such as CNC machines, for axes control.
• Robotics: For articulated arms and end-effectors where high torque density and dynamic response are needed.
• Printing Presses: For precise registration and web handling.
• Textile Machinery: In various processes requiring accurate material feeding and positioning.
• Material Handling Systems: In conveyors, pick-and-place units, and automated storage and retrieval systems.
• Food and Beverage Processing: Where hygiene, speed, and precise movements are essential.
