1MS310B-6B-A2/S011

The Bosch Rexroth Indramat 1MS310B-6B-A2/S011 from the 1MB High-Speed Asynchronous Motors series offers a robust motor size 310 frame with a motor length B and interchangeable windings code 6B, 6D, and 6E configurations. Engineered as a direct-drive asynchronous spindle motor stator, this unit is purpose-built for demanding industrial applications including high-precision turning, grinding, milling, transfer lines, and robotic systems. With an IP00 protection category, the stator core is designed for installation within an external housing rated at a minimum of IP54. Shadowing the stator’s enclosure requirements is its integrated liquid cooling system, which delivers superior thermal management and high power density without relying on ambient airflow. This combination of features ensures stable operation and consistent torque delivery in confined cabinet spaces.

In operational scenarios, the stator achieves up to 90 percent efficiency under nominal load, reflecting its optimized electromagnetic design and high-grade materials. Installation versatility is enhanced by compatibility with Rexroth Indramat drive controllers, which facilitate precise power and torque regulation as outlined in the official documentation. Safety mechanisms embedded in the design prevent hazardous runaways when configured and accessorized correctly; however, adherence to specified mounting and electrical parameters is essential to avoid unintended motion. The compact footprint and liquid-cooled topology allow for integration in modern machine tools where space constraints and thermal performance are critical factors.

Electrically, the 1MS310B-6B-A2/S011 requires an input rated current of 75 amperes to deliver an output torque of 260 newton-meters at a shaft speed of 700 revolutions per minute. This performance envelope makes it ideal for medium-speed spindle applications demanding sustained torque and speed stability. Additionally, the stator is covered by a global one-year warranty, ensuring factory support and peace of mind for OEMs and end users alike.
