1MR313F-A112

1MR313F-A112, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors The 1MR313F-A112 rotor is engineered specifically for integration with Bosch Rexroth Indramat’s high-speed asynchronous 1MB motor series, delivering precision spindle performance. It features a frame size of 313 and a frame length designation of F, matching the 1MB motor housing. This robust assembly ensures consistent alignment and dynamic balance during high-speed operation. Maintenance considerations, such as handling precautions and type plate visibility, are built into the design to simplify service and inspection.

Precision specifications define the capabilities of the 1MR313F-A112: an Inside Diameter of Rotor of 112 mm, a Motor Length of F, and a Motor Size of 313. The rotor employs a Fit Type of step interference fit for secure shrink-fitting onto the stator, while the Mounting Method follows a controlled sequence of preparation, thermal fitting, final dressing, and dynamic balancing. Heat generated by rotor losses is dissipated via a Cooling Method using liquid coolant, with transfer to a refrigeration subsystem. For safe transport, the Transport Method mandates plastic sling hoisting belts or a sheathed hook. A one-year Warranty covers material and workmanship from Wake Industrial upon global shipment.

By adhering to qualified installation protocols and precise shrink-fitting procedures, the 1MR313F-A112 delivers reliable, repeatable spindle performance in demanding machining and automation applications. Its standardized fit and comprehensive type plate markings—including type code, serial number, and manufacturing date—ensure traceability and simplify commissioning. This rotor’s combination of robust cooling management and interference-fit security makes it an ideal choice for high-speed, high-precision rotor assemblies.
