Product Description:

The MDD090A-N-040-N2M-110GB0 is a servo motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers in factory automation. It belongs to the MDD Synchronous Motors series and provides rotary motion that can be tightly coordinated by a drive, encoder, and PLC. By combining its integrated sensor system with electronic commutation, the unit supplies position-controlled torque for packaging lines, pick-and-place axes, and other cyclic machinery.

This model reaches a nominal speed of 4000 rpm, allowing rapid indexing when commanded by the drive. A continuous standstill torque of 3.7 Nm indicates the force available for holding or low-speed operation without overheating the windings. Power and feedback cables exit on side B, simplifying layouts where the controller is mounted behind the motor. The centering shoulder measures 110 mm, which provides a reference surface for flange alignment. Position data is returned through digital servo feedback (DSF), so the drive can execute high-resolution velocity and position loops. Standard dynamic balancing limits vibration at rated speed, the A-length housing keeps overall mass low, and the size 090 frame fits into machines that already use motors from the same diameter class. A keyed connector is supplied for quick electrical connection.

The motor is built without a blocking brake, so external measures are required when static holding under power-off conditions is necessary. A plain shaft is fitted with a shaft seal to reduce lubricant migration toward the bearing seat. The position transducer is an integrated multi-turn absolute encoder, enabling homing-free startups after power loss. Its standard shaft end on the drive side, together with a standard protective housing, supports direct coupling to gearheads or pulleys while leaving the non-drive side closed.
