1MR241D-A111, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors

The Bosch Rexroth Indramat 1MR241D-A111 rotor from the 1MB High-Speed Asynchronous Motors series delivers precision kinetic energy to high-speed spindle applications. It features a Motor Length of D, a robust Rotor Design of mit Stufenpressverband, and a Motor Size of 241 for optimal fit in compatible stators. Engineered under strict quality controls, the rotor achieves an operational efficiency of up to 95 percent under nominal conditions. Its high-metal-content construction also supports end-of-life recyclability, reducing environmental impact.

Detailed specifications underline its performance pedigree: the rotor’s moment of inertia is 0.135 kg·m², ensuring responsive acceleration and deceleration. It runs continuously at 2400 revolutions per minute with a Rated Current of 27 A and endures peak speeds up to 9000 revolutions per minute. The assembly weighs 18 kg, balancing mass for stability without sacrificing compactness. Thermal management is bolstered by integrated water cooling, while the grease-lubricated ball bearings minimize frictional heat and extend service life.

Integration into existing 1 MB asynchronous spindle motors is seamless thanks to its standard dimensions and mounting interfaces. The combination of high-speed capability, reliable cooling, and robust design makes the 1MR241D-A111 an ideal choice for CNC spindles, dynamic tooling spindles, and other precision machining applications. Bosch Rexroth Indramat’s proven track record ensures dependable operation and easy commissioning across global installations.
