Product Description:

Bosch Rexroth Indramat manufactures the MDD093C-N-040-N2M-130GB0 synchronous motor within the MDD Synchronous Motors series. The unit is specified as a motor for digital drive controllers, converting electrical command signals into controlled rotary motion for industrial indexing, feeding, and forming tasks. Its permanent-magnet design and closed-loop feedback support tight velocity regulation across varied loads in automated machinery. The feedback system helps the drive maintain stable speed and position control during frequent starts, stops, and load changes. When paired with compatible inverters, the motor supports repeatable accuracy in material-handling cells, packaging lines, machine tools, and other automated equipment where dynamic positioning is critical.

The rotor and stator are manufactured to a standard balancing quality to limit vibration at full operating speed and reduce mechanical stress on connected drive components. A centering diameter of 130 mm provides the locating surface for flange seating and preserves axial alignment with couplings. All power and feedback conductors exit on side B, keeping cable routing away from the driven machine frame. A keyed connector interface replaces fixed terminals, so the motor can be disconnected without removing hardwired leads. Position and revolution count are supplied by an integrated multiturn absolute encoder, and its data stream is relayed through digital servo feedback (DSF) to the control amplifier. The unit is delivered without a blocking brake, so static holding must be provided by external mechanisms, and its cast aluminum housing uses the standard finish for this frame.

During continuous duty, the rotor attains a nominal speed of 4000 rpm, giving short cycle times in pick-and-place or indexing equipment. Torque is transferred through a plain shaft, and the absence of a secondary shaft end on side B reduces overhung mass and simplifies sealing. A positive-lip shaft seal protects the front bearing against coolant spray and fine dust. The construction follows length code C, pairing that depth with the corresponding frame size to balance electromagnetic output and installation space in compact machine layouts.
