Product Description:

The MDD090C-N-030-N2M-110PA0 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for digital drive controllers, it converts controlled current from an inverter into precise rotary motion required by positioning axes and feed drives in automated machinery. Its mechanical outline and electrical interfaces match the series standard, supporting consistent installation and predictable operation across different machine platforms.

The motor delivers a continuous standstill torque of 10.4 Nm, allowing it to hold loads without overheating during static phases. During motion, it reaches a nominal speed of 3000 rpm, which corresponds to the electrical output of the companion converter and supports short axis cycle times. Accurate mounting is aided by the 110 mm centering diameter that seats the flange concentrically in the machine frame. All power and feedback cabling exits on side A, keeping service space clear on the remaining faces, and a sealed industrial connector supports rapid cable changes. Standard dynamic balancing limits residual vibration, and the standard housing provides a smooth surface that eases cleaning in production areas. A shaft seal is installed to protect the front bearing from contaminants and coolant splash.

Position data is transmitted through digital servo feedback (DSF), permitting the drive to close control loops using information from the integrated multi-turn absolute encoder. The rotor corresponds to length code C, producing the required stack height in the 090 frame without increasing diameter. Torque is delivered through a shaft machined with a keyway, enabling direct coupling to pulleys or rigid hubs. Because the unit is supplied without a blocking brake, holding at rest must be provided by external locking or active current when the axis is de-energized. A standard shaft end on side A only, with no secondary shaft, further reduces overall depth.
