Product Details:

The B&R 8MSA4S.R0-31 belongs to B&R 8MS series frame size 4 compact permanent magnet synchronous servo motor, built for high dynamic precision motion control. It adopts 131mm flange structure, fitted with R0 resolver position feedback and keyed shaft design. This servo motor delivers stable torque output at rated 3000rpm, max speed up to 4500rpm, featuring low cogging torque and fast dynamic response for accurate position, speed and torque control when paired with ACOPOSmulti servo drives. It uses self-cooled natural convection design, IP65 protection grade against dust and splash water. Dual rotatable connectors for power and encoder signals provide flexible wiring layout during machine integration. Built-in winding temperature sensor continuously monitors motor temperature to prevent overheating damage. Its robust aluminum housing has excellent shock and vibration resistance, suitable for long-term continuous operation inside industrial automation cabinets. It is perfectly matched with ACOPOSmulti servo drive modules to build high-precision multi-axis motion platforms. It is widely used in packaging machinery, textile production equipment, printing machines and special-purpose machinery automation, delivering reliable 8MSA4S servo motor 131mm flange resolver feedback key shaft performance and minimizing unexpected downtime of process production equipment.
