Product Description:

The MDD112B-N-030-N2L-130PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit converts commanded current into precise mechanical rotation for positioning, feed, or spindle axes in automated machinery. By integrating rotor-mounted permanent magnets with stator windings optimized for rapid vector control, the motor supplies repeatable motion profiles that match the fast update rates used in modern industrial automation. The housing and mechanical interface follow IEC mounting patterns, which support installation in a wide range of multiaxis systems.

Laid out for medium-frame machines, the motor develops a continuous standstill torque of 17.5 Nm, so static holding force is available without exceeding thermal limits. Under rated excitation it reaches a nominal speed of 3000 rpm, enabling direct coupling to high-speed ball screws or gearless conveyor drums. A centering pilot of 130 mm aligns the flange accurately on the machine interface, while frame size 112 and length code B indicate the motor’s mechanical envelope and stack length. Standard dynamic balancing helps reduce vibration during operation, and the unventilated housing relies on surface conduction for heat removal. Power and feedback are supplied through a keyed circular connector that simplifies cable routing and connection security.

Signal integrity is maintained by the integrated digital servo feedback, which sends rotor position data to the controller for tight velocity and position control. Cabling exits on Side A, keeping the connection point clear of adjacent axes in compact machine layouts. The motor has a shaft seal that helps keep coolant or cutting fluid away from the bearings, and the drive end is machined with a keyway for secure hub engagement. The motor is supplied without a blocking brake, so external holding force is required when the axis must remain fixed with power removed. A standard single-ended shaft is used, with no extension on side B, which keeps the output arrangement simple for common coupling methods.
