Product Description:

The MDD112B-N-030-N2L-130PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where closed-loop control is used to deliver accurate rotary motion on machine axes that must start, stop, and reverse under command. The housing uses the standard balancing arrangement for this product line, and the motor is supplied with a blocking brake to hold mechanical loads when drive power is removed. This layout suits positioning tasks in transfer units, handling systems, and similar automated equipment.

This motor delivers a continuous standstill torque of 17.5 Nm, giving the axis enough holding force for static process stages without exceeding thermal limits. Under rated excitation it reaches a nominal speed of 3000 rpm, allowing fast cycles while maintaining synchronous operation with the drive inverter. The blocking brake supplies 14.0 Nm of torque, which helps keep vertical or suspended loads from drifting after shutdown. A centering diameter of 130 mm aligns the motor on the mounting flange and supports accurate mechanical registration. Power and feedback conductors exit on Side B, and a single multi-pin plug keeps the electrical connection compact. The shaft is single-ended, so there is no unused rear shaft extension beyond the brake side.

Position data are returned through digital servo feedback (DSF), allowing high-resolution velocity and position control with the linked drive controller. A shaft seal is fitted to help retain lubricant and reduce contaminant entry when the motor is installed in enclosed machinery. The frame designation 112 identifies the housing size used for this motor body. Rotor torque is transferred through a keyway shaft, which supports positive-drive couplings used on many established machine designs. Standard balancing keeps running behavior predictable in normal horizontal mounting.
