1MR312C-A060

1MR312C-A060, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors opens a new benchmark in high-speed spindle solutions with its frameless rotor design and precision engineering. This unit offers a Motor Length of C and a robust Motor Size of 312, ensuring compatibility with a wide range of stator assemblies. Engineered with a Windings Code of Unspecified to accommodate custom winding configurations, the motor emphasizes flexibility in application. Built in accordance with stringent UL Compliance standards, the 1MR312C-A060 underscores Bosch Rexroth Indramat’s commitment to safety and industrial reliability.

Featuring a 60 mm Internal Diameter, the stator–rotor assembly delivers high power density at elevated rotational speeds while maintaining structural integrity. The rotor incorporates Class-F Insulation for enhanced thermal endurance, and the motor operates reliably within an Operating Temperature window of 0 to +40 °C. Designed for use in contaminant-free environments, it requires an installation location exempt from liquids and dust penetration, reflective of its basic Protection Certification level. Precision alignment within the stator bore is critical for vibration-free performance, and the unit’s frameless construction streamlines integration into custom spindle housings.

Integration of the 1MR312C-A060 into bespoke machinery offers designers a compact, modular solution that minimizes footprint while maximizing mechanical efficiency. The motor’s UL-certified design and specified environmental requirements simplify compliance with global safety codes and reduce certification overhead. Backed by Bosch Rexroth Indramat’s replacement warranty and comprehensive factory testing, this high-speed asynchronous rotor delivers consistent, long-term service life in advanced machining and dynamic spindle applications.
