1MR160B-A045

The 1MR160B-A045, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors represents a high-performance asynchronous rotor designed for precision and longevity. This model features an Inside Diameter of Rotor of 45 mm mated to a stator assembly, delivering a compact footprint with Motor Length rating of B and a Motor Size classification of 160. Engineered for integration into high-speed spindle applications, the rotor’s robust construction ensures smooth operation at elevated speeds. As part of Bosch Rexroth Indramat’s commitment to quality, each unit undergoes rigorous balancing and inspection before shipment.

In operation, the 1MR160B-A045 rotor achieves a Rated Torque of 16 Nm at a Rated Speed of 3000 RPM, while drawing a Nominal Voltage of 138 V. The stator winding presents a resistance of 0.264 Ω, paired with a rotor moment of inertia of 0.008 kg·m² that optimizes dynamic response. When assembled as a complete asynchronous motor, the system produces a Rated Power Output of 5 kW and sustains a Current Consumption of 36 A under continuous load. A Torque Constant of 0.52 Nm/A ensures predictable torque delivery, and the rotor weight of 6.8 kg balances inertia with rapid acceleration capabilities.

Designed for seamless integration, this rotor fits directly into the matching 4A winding stator, maintaining precise air-gap and alignment for turbulence-free rotation. Its operational temperature window from 0 … +40 °C and storage tolerance from -20 … +80 °C guarantee reliable performance across a variety of industrial environments. The 1MR160B-A045 rotor’s modular design simplifies installation and maintenance, making it an ideal choice for high-speed machining spindles, automated testing rigs, and precision assembly lines.
