MDD112D-N-020-N2M-180PB0

The MDD112D-N-020-N2M-180PB0 from Bosch Rexroth Indramat is a high-performance module in the MDD Synchronous Motors series designed for advanced digital drive controllers. This motor for digital drive controllers features a motor size 112 with motor length code D and a nominal speed of 2000 min⁻¹, delivering precise motion control across a broad operating envelope. It incorporates digital servo feedback (DSF) with an integrated multiturn absolute encoder to ensure accurate position tracking and repeatability. The unit is configured without blocking brake, offering flexibility for applications where external braking solutions are preferred. Built with a standard housing and balancing standard construction, the MDD112D ensures consistent dynamic behavior under varying load conditions.

The motor delivers a continuous torque at standstill of 38 Nm under a continuous current of 43.8 A, while peak performance reaches 134.8 Nm peak torque and 166.4 A peak current for short-duration high-demand cycles. The rotor moment of inertia of 0.023 kg·m² contributes to rapid acceleration and deceleration, making it ideal for dynamic positioning tasks. A centring diameter of 180 mm and a shaft type keyway ensure secure mechanical integration with driven equipment. Natural convection and surface cooling methods maintain optimal thermal conditions, supported by an ambient temperature range of 0 to 45 °C and reliable IP65 protection for dust and splash resistance. The motor’s shaft seal and standard shaft end protect internal components, while the overall mass of 59 kg reflects its robust build.

Engineered for seamless integration, the MDD112D uses a side B connector for power and feedback signals, allowing straightforward connection to drive controllers. The insulation class F rating and durable RAL 9005 prime black coat provide long-term reliability in industrial environments. Designed for mounting by qualified personnel, the motor supports natural convection cooling and optional surface cooling adaptations. Its combination of high torque density, precise encoder feedback, and rugged housing makes it well suited for robotics, packaging machines, semiconductor handling, and other applications demanding exacting performance and dependable operation.
