Product Description:

Bosch Rexroth Indramat manufactures the MDD090A-N-040-N2M-110PA0 as part of the MDD Synchronous Motors series. The motor is intended for use with digital drive controllers where precise speed and position control are required in automated machinery. By translating commanded current into regulated rotary motion, it drives axes in packaging, material-handling, and light machining equipment.

The centering pilot on the flange measures 110 mm, providing repeatable alignment during installation. Power and feedback plugs are positioned on side A of the housing and connect through a single connector, which simplifies cable routing inside compact cabinets. At standstill, the electromagnetic system can produce 3.7 Nm of continuous torque, allowing the axis to hold loads or begin motion without overheating. Under rated conditions, the rotor reaches a nominal speed of 4000 rpm, matching applications that need moderate velocity together with fine positioning. The unit has standard dynamic balancing to limit vibration, and its 090 frame with the A length code helps keep overall mass low for gantry or pick-and-place designs. A standard single-ended shaft is supplied, and the housing uses the standard cooling layout for this motor series.

Position information is provided by an internal integrated multi-turn absolute encoder, while commutation and velocity loops rely on digital servo feedback (DSF) signals routed to the drive. A keyway machined into the shaft transmits torque to gears or couplings without slip, and a fitted shaft seal limits lubricant migration when the motor is mounted in lightly contaminated areas. Because the model is supplied without a blocking brake, any required static holding force must be provided by the drive or by external mechanical components. Connections are made through the designated connector type, and the absence of a side-B shaft end keeps the envelope short for inline mounting.
