8MSA4M.R0-32 B&R 8MSA Servo Motor
Product Dimensions：
Product Description (Detailed Explanation)
The 8MSA4M.R0-32 is a brushless three-phase AC synchronous motor. The “8MSA” series is characterized by its compact design and high efficiency. This specific model utilizes high-quality permanent magnets to achieve a high torque-to-weight ratio.
It is designed to work seamlessly with B&R ACOPOS and ACOPOSmulti drive systems. The motor features an integrated encoder system (typically EnDat or Resolver, depending on the specific sub-configuration) that provides high-resolution feedback for closed-loop control. Its robust construction ensures reliable operation even in demanding industrial environments.

Product Advantages (Key Benefits)
-
High Dynamic Performance: Low rotor inertia allows for extremely fast acceleration and deceleration cycles, reducing overall machine cycle times.
-
Compact Design: Delivers high torque output in a small physical footprint, making it ideal for machines with limited mounting space.
-
Embedded Parameter Chip: Contains an electronic motor tag (EnDat) that automatically identifies the motor to the ACOPOS drive, simplifying commissioning and preventing incorrect parameter settings.
-
High Reliability: Features high-quality bearings and robust winding insulation to ensure a long service life under continuous operation.
-
Precision Accuracy: The high-resolution integrated feedback system enables sub-micron positioning accuracy when paired with high-performance B&R controllers.
Precautions (Important Notes)
-
Shaft Alignment: Ensure precise mechanical alignment with the load. Misalignment can lead to premature bearing failure and increased vibration.
-
Thermal Management: While designed for industrial use, ensure the motor is not obstructed. High ambient temperatures or heavy duty cycles without adequate cooling will trigger thermal protection.
-
Cable Handling: Always use B&R pre-assembled shielded cables. Using unshielded or poorly terminated cables can result in encoder signal interference and “Noise” faults.
-
Magnetic Safety: Use caution when the motor is disassembled; the internal permanent magnets are extremely strong and can attract metal objects or affect sensitive electronic devices.
Product Applications (Typical Use Cases)
-
Packaging Machinery: Controlling high-speed “flying cut-offs,” labeling heads, and pick-and-place grippers.
-
Textile Industry: Managing precise tension control and high-speed needle movement in weaving or knitting machines.
-
Electronics Assembly: Powering XY tables and component placement heads in SMT (Surface Mount Technology) lines.
-
Printing Presses: Synchronizing feed rollers and color registration units where zero-backlash and high speed are required.
-
Woodworking: Driving high-speed routing spindles and feed axes in CNC machining centers.
