Product Description:

The MDD112C-N-040-N2M-130GB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precise shaft rotation for positioning, feed, and auxiliary axes in automated equipment. The internal multiturn absolute encoder provides immediate position feedback to the control loop, which removes the need for homing routines after startup and supports fast, repeatable motion in industrial automation.

Its continuous stall torque is rated at 28.0 Nm, allowing the axis to hold a load steadily without overheating while motion is paused. During operation, the rotor can reach a nominal speed of 4000 rpm, so the drive must supply the matching electrical frequency for synchronous operation. The motor case aligns to the machine frame through a centering pilot of 130 mm, which helps maintain concentric alignment between the stator and the coupled mechanics. Standard balancing keeps residual vibration low at peak speed, and the housing follows the usual form used in this motor frame. An integrated blocking brake delivers 40.0 Nm of holding torque, so vertical or suspended axes can remain stationary when power is removed. Position data returns to the controller through digital servo feedback, which carries absolute position information and diagnostic signals over a serial channel.

Power and feedback conductors exit on side B, which can simplify cable routing when the drive electronics are mounted behind the motor. There is no shaft end on that side, so the rear of the motor remains compact. A keyed circular connector provides a secure connection to the machine harness and supports orderly cable attachment. The motor uses a plain shaft with a shaft seal to help keep coolant and dust away from the front bearing area. Length code C indicates the mid-length version of the MDD112 frame, giving the motor a higher torque capacity without increasing its overall width.
