8MSA3L.E2-73 B&R

Product Dimensions：

The B&R 8MSA3L.E2-73 is a high-performance three-phase synchronous servo motor from the 8MS series manufactured by B&R Industrial Automation. This motor is specifically engineered for high-dynamic applications that require precision, high torque density, and compact dimensions. It belongs to a generation of motors designed to integrate seamlessly with B&R ACOPOS drive systems, providing a complete and optimized motion control solution.

Product Specifications

• Motor Series: 8MS (Synchronous motors)

• Size: 3 (Frame size designation)

• Length: L (Long version, indicating higher torque output compared to standard lengths)

• Winding Type: E (Specific winding design optimized for certain speed and voltage characteristics)

• Encoder System: 2 (Equipped with a high-resolution EnDat 2.2 multi-turn inductive encoder for absolute position feedback)

• Holding Brake: Integrated mechanical holding brake for securing the load when the motor is de-energized

• Nominal Speed: Typically ranges around 3000 to 6000 RPM depending on the drive configuration

• Stall Torque: High continuous torque capability due to the "L" frame length

• Cooling: Self-cooling (Natural convection)

• Protection Class: IP64 standard (protected against dust and splashing water)

• Connection Type: Right-angle swiveling double-plug connectors for power and encoder signals

Product Advantages

• High Torque Density: The use of high-quality permanent magnets and an optimized stator design allows for a very high torque-to-volume ratio, making it ideal for machines with limited installation space.

• Exceptional Dynamics: The low rotor inertia ensures rapid acceleration and deceleration, which is critical for reducing cycle times in automated machinery.

• Precision Feedback: The integrated EnDat 2.2 absolute encoder provides extremely high resolution and accuracy, eliminating the need for homing procedures and ensuring stable control loops.

• Robust Construction: Designed for industrial environments, the motor features high-quality bearings and a rugged housing to ensure a long service life even under demanding operational cycles.

• Seamless Integration: When paired with B&R ACOPOS drives, the motor's electronic "embedded parameter chip" allows the drive to automatically identify the motor and configure the control parameters, significantly reducing commissioning time.

Important Considerations

• Thermal Management: While self-cooling, the motor must be mounted on a heat-conductive surface (typically the machine frame) to ensure heat dissipation. Overloading the motor without adequate cooling can lead to permanent magnet damage.

• Brake Usage: The integrated holding brake is designed as a parking brake, not a dynamic braking system. It should not be used to stop a moving load except in emergency situations, as this will lead to premature wear.

• Cable Handling: Ensure that the power and encoder cables are shielded and routed away from high-noise electrical lines to prevent signal interference. Use the specified B&R mating connectors for reliable connectivity.

• Shaft Loading: Do not exceed the maximum permissible radial and axial forces on the motor shaft, as this can lead to bearing failure.

• End of Life: As with many specialized industrial components, verify current availability and lead times, as B&R periodically updates their motor lines with newer efficiency-standard models.

Product Applications

The 8MSA3L.E2-73 is versatile and finds use in any application where dynamic movement and high-precision positioning are mandatory.

• Packaging Machinery: Used in "pick and place" systems, filling machines, and labeling applications where high-speed synchronization is required.

• Printing and Paper: Controlling tension and positioning in high-speed printing presses or converting equipment.

• Metal Processing: Powering feed axes in CNC machines or specialized metal-forming equipment.

• Robotics: Acting as the drive motor for articulated robot arms or Cartesian coordinate robots.

• Textile Industry: Precision control for weaving or spinning machinery where synchronized motion is critical for product quality.
