B&R 8MSA3L.E2-73 Servo Motor

Product Dimensions：

The B&R 8MSA3L.E2-73 is a high-performance synchronous servo motor from the 8MSA series, designed by B&R Industrial Automation (part of the ABB Group). These motors are engineered for high-dynamic applications where precision and reliability are paramount.

Detailed Product Description

The 8MSA series is characterized by its low-inertia design, which allows for extremely high acceleration and deceleration rates. The “L” in the model name typically indicates a specific stack length, providing a balance between compact size and high torque output. This motor is brushless, meaning it requires minimal maintenance and offers a long service life.

Key Product Parameters

While specific electrical ratings can vary slightly based on the drive pairing, the standard specifications for the 8MSA3L series are as follows:

Product Advantages

• High Dynamics: The low-inertia rotor allows the motor to respond to command changes almost instantaneously, making it ideal for high-speed cycling.

• Precision Feedback: Equipped with an EnDat 2.2 absolute encoder, providing high-resolution positioning and simplified commissioning through an “electronic terminal strip.”

• Compact Footprint: High power density means you get more torque out of a smaller physical motor, saving valuable machine space.

• Seamless Integration: Fully compatible with B&R’s ACOPOS drive family, allowing for “plug-and-play” configuration.

Important Considerations (Precautions)

• Thermal Management: Ensure adequate ventilation. If the motor is buried deep inside a machine without airflow, it may derate or overheat.

• Cable Handling: Always use shielded B&R motor cables to prevent EMI (electromagnetic interference) which can corrupt encoder signals.

• Shaft Loading: Do not exceed the maximum radial and axial force limits specified in the technical manual, as this will lead to premature bearing failure.

• Brake Usage: If equipped with a holding brake, remember it is for holding only, not for stopping a moving load (emergency use only).

Product Applications

The 8MSA3L.E2-73 is a “workhorse” for precision-heavy industries:

• Packaging Machinery: High-speed pick-and-place, labeling, and capping.

• Printing Industry: Precise tension control and register alignment.

• CNC Machining: Tool changers and auxiliary axes.

• Textile Industry: High-speed yarn guiding and weaving controls.
