MDD112D-N-020-N2M-130GB2

The Bosch Rexroth Indramat MDD112D-N-020-N2M-130GB2 servo motor represents a high-performance solution in the MDD Synchronous Motors series, delivering precise motion control for demanding industrial applications. This unit provides continuous torque at standstill of 38.0 Nm and features a robust holding brake torque of 40.0 Nm for secure load retention. Equipped with an integrated multiturn absolute encoder, the motor offers digital servo feedback (DSF) to ensure accurate position measurement and advanced control. The plain output shaft and shaft seal protect internal components while facilitating direct coupling to driven loads. The motor’s nominal speed of 2000 min⁻¹ and flange-mounted design enable smooth integration with standard digital drive controllers.

The technical specifications of the MDD112D-N-020-N2M-130GB2 include a motor size 112 with a motor length code D and a centering diameter of 130 mm. The housing is a standard housing utilizing natural convection cooling, with an option for surface cooling on request. Connection to the drive controller is through a high-reliability connector on side B, and the shaft end is standard (without side B shaft end). The motor is statically balanced to standard specifications, reducing vibration and extending bearing life. Integrated components include a blocking brake rated at 24 V DC release voltage drawing 1.3 A, with a release delay of 150 ms and a clamping delay of 30 ms.

Operational performance is defined by the motor’s ability to maintain continuous torque of 38.0 Nm at standstill and manage dynamic loads with precision. The built-in blocking brake holds loads securely even when power is removed, preventing drift in vertical or inclined axes. With a total system mass of approximately 62.5 kg (motor 59 kg plus brake 3.5 kg), the assembly offers a compact footprint for high-force applications. The multiturn encoder ensures position tracking across multiple revolutions without battery backup, while the plain shaft simplifies mechanical interfacing. Operating temperature ranges from 0 to 45 °C ambient, enabling reliable performance in standard industrial environments.

System integration is streamlined for use with digital drive controllers within the Bosch Rexroth Indramat ecosystem. The MDD112D-N-020-N2M-130GB2 is optimized for precision applications such as robotic manipulators, CNC machine tools, and automated handling systems. Its flange-mount configuration and standardized 130 mm centering diameter facilitate quick replacement and interoperability across machine platforms. This servo motor is ideally suited for engineers seeking proven reliability, accurate feedback, and safe load holding in synchronized multi-axis installations.
