Product Description:

The MDD112C-N-030-N2M-130GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to pair with digital drive controllers, it turns commanded current into precise rotary motion, allowing positioning or velocity control on machine tools, packaging lines, and material-handling axes that demand fast dynamic response. The motor is intended for closed-loop applications in which fast starts, controlled deceleration, and repeatable motion are required. The motor has no second shaft end, which simplifies coupling to gearboxes or pulleys.

This model supplies a continuous stall torque of 28.0 Nm, so the axis can hold load without additional gearing or cooling while stationary. When energized to its rated winding frequency, it reaches a nominal speed of 3000 rpm. A blocking brake integrated at the non-drive end delivers 40.0 Nm of static holding torque to secure vertical or overhung loads during power loss. For accurate mechanical registration, the front flange has a centering diameter of 130 mm, and both power and feedback connectors exit on side B. The connection style is a keyed circular connector, and the housing and rotor are balanced to the standard grade. The motor uses size code 112 and length code C for its frame envelope.

Closed-loop control relies on digital servo feedback that transmits real-time position and speed data from the integrated multi-turn absolute encoder. This feedback allows the connected drive to monitor rotor position continuously and correct speed deviations during changing load conditions. The mechanical output is provided through a plain shaft, and a fitted shaft seal helps prevent coolant or lubricants from entering the bearing chamber. This arrangement supports stable motion in continuous industrial service and reduces the risk of contamination at the output end. The motor uses a standard housing.
