Product Description:

The MDD112B-N-030-N2M-130PB0 is a synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it supplies rotary motion to axes that require repeatable positioning and stable speed regulation in industrial automation equipment. The motor uses a size 112 frame and a standard housing, giving it a consistent mounting envelope, while standard balancing keeps vibration at a level suitable for precision assemblies.

A centering diameter of 130 mm helps align the flange accurately with machine plates or gearbox interfaces. The motor can sustain a continuous standstill torque of 17.5 Nm, which allows it to support static loads without excessive temperature rise in the windings. During operation, the rotor reaches a nominal speed of 3000 rpm, making it suitable for motion systems that need a broad working speed range. Position data comes from an integrated multi-turn absolute encoder, and the signal is returned to the controller through digital servo feedback (DSF). This feedback arrangement allows the drive to monitor rotor position continuously and support closed-loop motion control without adding a separate encoder at the load.

The motor is supplied without a blocking brake, so holding during power-off conditions must be provided by the drive or by an external mechanical device. Power and feedback connections are oriented on side B, which can help keep cable routing away from the shaft area in many machine layouts. The output shaft uses a keyway for positive torque transmission, and it is fitted with a shaft seal to help limit dust or oil ingress near the bearing zone. The standard shaft end on the drive side and the B-length stator package support installation in medium-inertia axis arrangements where predictable mechanical fit and protected shaft output are required.
