1MR310F-A094

The Bosch Rexroth Indramat 1MR310F-A094 rotor from the 1MB High-Speed Asynchronous Motors series is engineered to the highest precision and integrates seamlessly with frameless spindle motors. Featuring a Motor Size 310 rating, a robust Motor Length F, and an Inside Diameter of Rotor 94 mm, this rotor delivers optimal performance in high-speed applications. Its Fit Type step interference fit ensures zero backlash and reliable torque transmission, while a processed outer diameter grants tight tolerances for accurate alignment. Designed in compliance with DIN ISO 2768, Part 1, the rotor’s manufacturing tolerances guarantee consistent operation under demanding conditions.

Constructed with a Moment of Inertia 0.723 kgm2, the 1MR310F-A094 balances dynamic response with rotational stability and mounts on spindles up to 408 m in length. The unit is assigned a Protection Class IP00 per IEC 60529:1989, protecting critical surfaces without compromising heat dissipation. A Max Temperature Resistance 200 °C rating ensures safe operation during high-speed runs, while a dedicated cooling fluid absorbs the majority of power losses. Threaded securing pins prevent loosening under centrifugal loads, and the stepped interference fit maximizes concentricity. Storage is flexible: the rotor may be oriented horizontally or vertically and must be lifted only with approved plastic sling belts.

Each rotor includes a clearly visible type plate listing type designation, certification, maximum speed, and mass, simplifying identification and maintenance. The 1MR310F-A094 is backed by a Warranty Period 1 year, safeguarding against manufacturing defects and ensuring reliable lifecycle support. With its precision-fit housing, processed outer diameter, and dynamic balance certification, this rotor is ready for global shipment and deployment in cutting-edge machining and high-speed automation systems.
