1MR160D-A055

1MR160D-A055, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors The 1MR160D-A055 rotor from Bosch Rexroth Indramat is engineered for high-speed applications within the 1MB motor family, delivering precision and robustness in one compact unit. This component features a Motor Length of D, Motor Size 160, and a stepped interference fit that ensures a friction-locked yet removable mounting interface. It is finished to exacting tolerances to guarantee repeatable performance when integrated with compatible stators and shafts. Designed for frameless motor assemblies, the 1MR160D-A055 offers simplified machine integration without compromising on dynamic efficiency.

In operation, the rotor exhibits a Moment of Inertia of 0.0121 kgm² and weighs 7.3 kg, optimizing response time and load handling in high-acceleration scenarios. The internal diameter measures 55 mm, matching standard 1MB motor housings, while an insulation rating of Class F allows continuous operation across a Functional Ambient Temperature range of 5 – 45 °C. It carries a Rated Current of 48 A in coordination with the 1MB motor drive to deliver consistent torque. The laminated core and integrated sleeve with balancing ring—complete with tapped holes for on-site fine balancing—enhance stability and minimize vibration at speeds approaching maximum RPM.

Bosch Rexroth Indramat’s stepped interference fit ensures the rotor fits precisely onto the spindle after pre-heating to approximately 200 °C, locking in optimal dimensions upon cooling for reliable operation. The robust construction and high-precision finish facilitate seamless integration into existing automation lines, reducing commissioning time. Backed by a one-year global warranty, the 1MR160D-A055 rotor delivers dependable performance in demanding industrial environments.
