B&R 8LSA44.EB030D100-3: Synchronous Servo Motor

This part number specifies a particular configuration within B&R’s 8LS synchronous motor series. These motors are known 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.
• Rated Speed: Typically 3000 RPM (revolutions per minute).
• Nominal Torque: Around 4.6 Nm (Newton-meters).
• Stall Torque: Approximately 6 Nm.
• Nominal Current: Generally 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.
• Protection Class: IP64, indicating it is protected against dust ingress and splashing water from any direction.
• Pole Pairs: Typically 5 pole pairs.
• Centering Diameter: 95 mm (for mounting).
• Feedback System: While not explicitly stated in the brief snippets, B&R 8LS motors usually come with an integrated feedback system (e.g., encoder) for precise position and speed control when paired with a compatible servo drive.
• Brake: The “EB” in the part number indicates it typically does not include a brake. If it had a brake, the code would usually be different (e.g., “DB”).

Decoding the Part Number (General 8LS Structure):

While the exact meaning of every character can be complex and specific to B&R’s internal coding, here’s a general breakdown that applies to similar 8LS part numbers:

• 8LS: Denotes the 8LS Synchronous Motor series.
• A44: Likely refers to the motor size, design, or performance class.
• EB: Often indicates the connection type and whether a brake is present (e.g., “EA” for smooth shaft, angled connector, no brake; “EB” for similar configuration; “DB” for brake). In this case, “EB” suggests angled swivel connectors and no brake.
• 030: Could relate to the nominal speed (e.g., 3000 rpm).
• D100: Could denote specific encoder or feedback system details (e.g., 100 might refer to a specific encoder resolution).
• 3: Often indicates the version or a specific variant.

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.
• 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.
