1MR160E-A060

1MR160E-A060, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors rotor delivers a maintenance-free frameless spindle solution within the future-proof Rexroth IndraDrive drive system. This model features a frame size of 160 and a frame length of E, engineered for high-speed asynchronous operation. It combines high power density with high rigidity to withstand dynamic loads and maintain precision at elevated rotational speeds. Ideal for advanced C-axis machining, thread cutting, turning, grinding, milling, and spindle positioning applications in demanding production environments.

Built with an Inside Diameter of Rotor of 60 mm, the 1MR160E-A060 achieves a Moment of Inertia of 0.015 kgm², balancing rapid acceleration with rotational stability. The rotor weighs 10.2 kg and incorporates Balancing Rings with tapped holes that allow fine vibration tuning to meet DIN VDE 0530 severity grades. A Laminate Core Sleeve optimizes magnetic flux efficiency, while a Multiple Die Press Group frictionally engages the rotor to the spindle via precision Graduated Fitting Surfaces. Rated to protection category IP00, this unit requires Protective Seals for safe operation in foggy or damp atmospheres, preserving internal components.

Seamless integration with the IndraDrive control platform simplifies installation and commissioning through standardized mounting interfaces and plug-and-play compatibility. The precisely balanced construction and robust magnetic design ensure reliable spindle positioning with minimal vibration, extending service intervals and reducing maintenance costs. With its compact, frameless form and global one-year warranty, the 1MR160E-A060 is an ideal choice for high-speed machining centers, grinding spindles, and automated manufacturing cells demanding long-term reliability and performance.
