MDD112B-N-015-N2M-130GB0

The Bosch Rexroth Indramat MDD112B-N-015-N2M-130GB0 servo motor from the MDD Synchronous Motors series represents a high-precision, digital AC drive solution engineered for demanding synchronization tasks. This motor integrates a robust sealed housing with an IP65 protection rating for both power and feedback cable connections, ensuring reliable operation in harsh environments. Its brushless design and maintenance-free operation extend service intervals, while the plain output shaft accommodates flexible coupling arrangements. The unit’s digital servo feedback with integrated multiturn encoder enables precise position control and direct integration with digital drive controllers. Intended for use in grinding machines and other precision equipment, this motor operates effectively up to an installation altitude of 5000 m above sea level.

Technical specifications underscore its performance and integration readiness. The motor delivers a continuous torque at standstill of 17.5 Nm and achieves a theoretical maximum torque of 60.5 Nm under peak conditions. Its nominal speed of 1500 min⁻¹ corresponds to a torque constant of 1.25 Nm/A (20 °C) and a winding resistance of 0.85 Ω (20 °C). The drive supports a peak current of 55.3 A and features a rotor moment of inertia of 120 × 10⁻⁴ kg·m² for stable dynamic response. The center diameter of 130 mm and motor size 112 allow direct flange mounting, while the plain shaft and standard shaft end facilitate straightforward mechanical coupling. The motor employs digital servo feedback (DSF) and is classified as a motor for digital drive controllers, with connection direction on Side B and standard housing balance.

Operational features include a factory-balanced rotor for minimal vibration and radial shaft cooling to maintain thermal stability under continuous operation. Bearings are lubricated for lifetime service, with a floating bearing on Side A and a fixed bearing on Side B ensuring reliable load support. The absence of a blocking brake reduces mechanical complexity and maintenance requirements. This unit’s sealed enclosure and robust construction allow operation in accordance with IEC 721-3-3 weatherproof stationary conditions, even under poor environmental scenarios. Rigorous design controls ensure consistent performance across long duty cycles, making it suitable for 24/7 production environments.

System integration is simplified via direct compatibility with Bosch Rexroth digital drive controllers, leveraging built-in multiturn encoder feedback and plug-and-play motor feedback connectors. The MDD112B-N-015-N2M-130GB0 is optimized for synchronization in precision grinding, machine tools, and automated assembly systems. Its high torque density, advanced feedback, and sealed design support applications in aerospace manufacturing, automotive component grinding, and packaging machinery. With straightforward mounting and robust electrical interfaces, this motor streamlines machine design and enhances overall system reliability.
