MDD112B-N-020-N2M-180PB2

The Bosch Rexroth Indramat MDD112B-N-020-N2M-180PB2 servo motor represents a high-performance solution within the MDD Synchronous Motors series, engineered for precision and reliability in demanding industrial environments. This compact digital AC servo motor features digital servo feedback with an integrated multiturn absolute encoder for absolute position evaluation, ensuring accurate control even after power interruptions. It delivers smooth electronic commutation and supports a nominal speed of 2000 min⁻¹, making it suitable for a wide range of motion control tasks. Equipped with a robust blocking brake offering a holding torque of 40.0 Nm, the unit provides safe, fail‐secure positioning under load. The motor’s sealed housing meets IP65 ratings on DIN 40 050–compliant power and feedback cables, ensuring resistance to dust and water ingress.

Manufactured by Bosch Rexroth Indramat, the MDD112B-N-020-N2M-180PB2 is defined by precise mechanical dimensions and balanced dynamics. It features a motor size 112 with a motor length code B and a centering diameter of 180 mm to facilitate direct mounting of pinions or belt pulleys. Standard balancing ensures low vibration during high-speed operation, while the standard housing is protected by a black prime coating resistant to yellowing, weathering, and chalking. The motor’s continuous torque at standstill is rated at 17.5 Nm, and its standard inertial design supports high radial loads for versatile installation. A shaft end without side B extension simplifies integration into existing machinery footprints.

Operational reliability is further enhanced by an optical multiturn absolute encoder and high-resolution feedback, delivering precise position and velocity data via motor feedback (DSF). The output shaft with keyway and integrated shaft seal prevent fluid ingress, maintaining long-term performance in adverse conditions. Natural convection or surface cooling dissipates heat efficiently, with an embedded thermal sensor providing overload protection within the winding. The choice of a side-mounted connection direction (Side B) and a robust connector interface streamlines cable management and reduces installation time. These features combine to ensure continuous, maintenance-minimized operation across varied duty cycles.

Seamless system integration is supported by the motor’s compatibility with digital drive controllers and standard industry interfaces, classifying it as a versatile product type: Motor for digital drive controllers. Its form-fitting torque transmission, absolute encoder retention, and fail-safe brake make it ideal for applications in textile machinery, automated handling systems, printing presses, and packaging lines. The MDD112B-N-020-N2M-180PB2’s balance of compact size, high torque density, and advanced feedback positions it as a go-to solution for OEMs seeking precision motion control in dynamic production environments.
