2AD101D-B05OA1-BD03-A2N1
The 2AD101D-B05OA1-BD03-A2N1 spindle motor by Bosch Rexroth Indramat is a high-precision AC induction machine in the renowned 2AD 3-Phase Induction Motors series, specifically optimized for size 101 applications. This Product Type combines a compact Motor Length Code D housing with a robust Motor Size Code 101 frame, delivering an optimal power-to-size ratio. The unit weighs 80 Kg, ensuring structural integrity while maintaining manageable mass for installation. It features a Rotor moment of inertia of 0.028 Kgm2 and a built-in NTC thermistor winding protection system to monitor thermal conditions in real time. With an integrated axial motor blower operating at 230V and providing an air volume of 460 m3/h, the motor achieves efficient cooling and continuous duty capability.
The performance profile of the 2AD101D-B05OA1-BD03-A2N1 spindle motor emphasizes precision and dynamic response. Its High-resolution motor feedback device supports a resolution of 1/2000000th revolution, enabling sub-micron positional accuracy. The motor’s squirrel-cage induction design operates asynchronously to minimize slip and optimize torque delivery across varying load conditions. Encapsulated in a surface-ventilated configuration with a fixed blower unit, this assembly maintains thermal equilibrium under sustained operation. Bearing life expectancy is enhanced by standard Bearings lubrication protocols, ensuring consistent radial and axial load handling at a Vibration Grade R rating. The Winding Code BD further denotes a robust winding insulation class suited for industrial environments.
Reliability and system integration are central to the 2AD series philosophy. The motor supports Flange mounting and features a Smooth shaft without seal on Side A, with Side B delivered without shaft end to accommodate specialized coupling solutions. Power terminals are oriented To Side A at the Top of the frame, facilitating streamlined cable management in machine tool enclosures. Offered without holding brake, the design reduces complexity where fail-safe braking is managed externally. When combined with Rexroth’s digital drives—INDRADRIVE, DIAX, or ECODRIVE—the 2AD101D-B05OA1-BD03-A2N1 delivers an intelligent drive ecosystem. Its versatile interface and high power density make it ideal for CNC machining spindles, precision grinding systems, and semiconductor wafer handling, where reliability and repeatability are paramount.
