8MSA4M.R0-32 B&R

8MSA4M.R0-32 B&R Input module

Product  Description：

The 8MSA4M.R0-32 is part of the 8MS series, which is characterized by its high power density and low inertia. The "4M" designation typically refers to the motor size and length, while the "R0" indicates a specific resolver or encoder feedback configuration. This motor is designed to work seamlessly with B&R ACOPOS servo drives, allowing for plug-and-play integration via embedded parameter chips that automatically identify the motor to the drive. It features a robust housing and high-quality bearings to ensure a long service life even under continuous operation.

Product Parameters

• Motor Type: Synchronous 3-phase AC servo motor

• Nominal Speed: Typically $3000 \text{ rpm}$ (depending on the specific drive configuration)

• Stall Torque: Approximately $3.4 \text{ Nm}$ to $4.0 \text{ Nm}$ (subject to cooling and drive settings)

• Maximum Speed: Up to $6000 \text{ rpm}$

• Feedback System: Integrated Resolver for precise position and speed feedback

• Enclosure Rating: IP64 as standard, providing protection against dust and splashed water

• Insulation Class: Class F ($155\text{°C}$)

• Shaft Design: Plain shaft (no keyway) for high-precision coupling, though variants may exist

• Connection: Angled double-connector system for power and encoder signals

Product Advantages

One of the standout advantages of the 8MSA4M.R0-32 is its High Power Density. The motor delivers significant torque relative to its small frame size, allowing machine builders to reduce the overall footprint of their equipment. The Low Rotor Inertia enables extremely fast acceleration and deceleration cycles, which is critical for high-speed pick-and-place or packaging tasks. Furthermore, the Embedded Parameter Chip simplifies commissioning significantly; the ACOPOS drive reads all motor limits and parameters automatically, preventing configuration errors. The high-quality construction also results in Low Cogging Torque, ensuring smooth rotation even at very low speeds.

Important Considerations and Precautions

When installing or maintaining the 8MSA4M.R0-32, certain precautions are vital for safety and longevity. First, Handle with Care: The internal feedback resolver is a precision optical or magnetic component; dropping the motor or striking the shaft with a hammer during mounting can permanently damage the feedback system. Second, Thermal Management: While the motor is rated for high temperatures, ensuring adequate ventilation and heat dissipation from the mounting flange will extend the life of the windings and bearings.

Third, Wiring Integrity: Always use pre-assembled B&R cables to ensure electromagnetic compatibility (EMC) and to prevent signal noise from affecting the resolver feedback. Fourth, Shaft Loading: Do not exceed the specified radial and axial force limits on the motor shaft, as excessive loads will lead to premature bearing failure. Finally, ensure the Grounding is properly executed through the motor housing and cable shields to prevent stray currents from damaging internal components.

Product Applications

The B&R 8MSA4M.R0-32 is used in various sectors where motion control must be both fast and accurate.

• Packaging Machinery: Used in labeling, bagging, and capping machines where quick, repetitive motions are required to maintain high throughput.

• Plastic Processing: Integrated into injection molding robots and handling systems for precise part extraction.

• Printing and Paper: Employed in tension control and high-speed feeding mechanisms where synchronization between multiple axes is mandatory.

• Electronics Assembly: Ideal for SMT (Surface Mount Technology) machines and semiconductor handling due to its high dynamic response and precision.

• Metalworking: Used in small CNC units or specialized drilling and milling attachments where space is limited but torque requirements are high.
