Product Description:
The MDD112B-N-030-N2M-130PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts precisely modulated inverter current into controlled rotary motion. This operating role suits positioning axes and speed-regulated spindles in automated machining cells, packaging lines, and other industrial equipment. Its synchronous design allows the drive to coordinate torque production and rotor position precisely across low-speed indexing and higher-speed travel segments.
At standstill, the motor can deliver a continuous torque of 17.5 Nm, allowing it to hold loads without external gearing or overheating. Once in motion, it reaches a nominal speed of 3000 rpm, matching drives that operate on common inverter outputs. Mechanical centering is simplified by a 130 mm centering diameter, while standard dynamic balancing helps reduce vibration during operation. Power and feedback leads exit on side B through a sealed connector, which helps keep cable routing compact. The housing is the standard unvented version, and a shaft seal is fitted to block airborne coolant or dust. Size code 112 and length code B indicate the active stack height, and the shaft end uses the standard configuration without a second shaft on side B.
Position retention during power loss is provided by an integral holding brake with 14.0 Nm of locking torque. High-resolution motion feedback is obtained through digital servo feedback with an integrated multi-turn absolute encoder, giving the drive controller immediate knowledge of shaft angle after startup. The output shaft is machined with a keyway, enabling direct coupling to pulleys or rigid couplings without additional machining. This arrangement is useful on vertical or indexing axes that need controlled stopping, secure holding during power loss, and accurate position reporting after restart. It also allows the motor to remain part of a closed-loop system during both motion and standstill.
