MDD112D-N-015-N2L-130PB1

The Bosch Rexroth Indramat MDD112D-N-015-N2L-130PB1 servo motor is a high-performance member of the MDD Synchronous Motors series, engineered for precision motion control in demanding industrial environments. This motor delivers robust torque through a continuous torque at standstill of 38.0 Nm and features a nominal speed of 1500 min⁻¹, making it suitable for applications requiring stable low-speed operation. Equipped with digital servo feedback (DSF), the unit provides precise position and velocity monitoring, while the integrated blocking brake with 14.0 Nm holding brake torque ensures immediate and reliable load arrestment. With a keyway output shaft and 130 mm centering diameter, the MDD112D-N-015-N2L-130PB1 offers robust mechanical coupling and straightforward installation. The combination of compact dimensions and a durable IP65-rated housing underscores its suitability for harsh industrial environments.

Detailed technical specifications define the MDD112D-N-015-N2L-130PB1’s capabilities. The motor size of 112 and motor length code D identify its form factor, while the housing: standard and shaft seal: with shaft seal ensure environmental protection. Electrical parameters include a winding resistance of 0.39 Ω and winding inductance of 5.9 mH, optimizing the motor’s electrical time constant. The moment of inertia of 230×10⁻⁴ kg·m² reflects the rotor’s dynamic characteristics, and the use of rare-earth permanent magnets guarantees high power density. Connection is achieved via a side-mounted connector (connection direction: Side B), and the shaft end is standard (without side B shaft end). The motor balancing class is Standard, reducing vibration without special balancing procedures.

Operational features emphasize reliability and dynamic performance. The MDD112D-N-015-N2L-130PB1 produces a theoretical torque of 132.4 Nm under peak conditions, with a peak current draw of 110.5 A managed by advanced thermal design and a 120-minute thermal time constant. Natural and surface cooling channels are integrated within the case to dissipate heat efficiently, maintaining the insulation class F rating under continuous operation. A built-in radio interference suppression method minimizes electromagnetic emissions, ensuring compliance with industrial EMC standards. The motor feedback system combined with the blocking brake—which operates at 24 VDC with clamping and release delays of 30 ms and 70 ms respectively—provides precise stopping capability and safe holding in vertical or dynamic loads.

System integration is simplified through its compatibility as a motor for digital drive controllers, enabling plug-and-play operation with Bosch Rexroth Indramat drive converters and servo controllers. The connector interface and standard mounting configuration support rapid installation and replacement. Its robust design and precise feedback make it ideal for packaging machinery, CNC tools, and automated assembly lines where accuracy and uptime are critical. The MDD112D-N-015-N2L-130PB1 delivers a reliable, high-performance solution for modern automation systems.
