1MR310F-A112/S022 from Bosch Rexroth Indramat is a high-performance spindle motor in the 1MB High-Speed Asynchronous Motors series. It delivers 30 kW of continuous power at a nominal 380 V and 47 A, optimized for demanding industrial automation. The unit’s robust construction weighs 145 kg yet maintains a compact 400 mm total length for versatile mounting. An integrated incremental encoder ensures precision feedback under dynamic loads.
The motor features liquid-cooled thermal management for consistent operation up to its 200 Hz electrical frequency and a max mechanical speed of 8000 RPM. Housed in a IP54 enclosure, it affords dust and splash protection in harsh environments. Its flange mounted design and axial runout after installation ≤ 0.04 mm support high-accuracy alignment. A rotational inertia of 0.723 kg·m² and a winding resistance of 0.363 ohm (20 °C) balance rapid acceleration with torque stability across the speed range.
Engineered for integration into turning, milling, and grinding spindles, the 1MR310F-A112/S022 seamlessly couples to CNC drives via its precise bore tolerances and incremental encoder feedback. Its liquid-cooling circuit reduces thermal drift, enhancing reliability in continuous-duty cycles. Combined with Bosch Rexroth Indramat control systems, this spindle motor delivers exceptional rigidity, dynamic response, and uptime for critical manufacturing applications.
