Product Description:

The MDD090B-N-040-N2M-110GB2 servo motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts inverter output into precise mechanical motion for automated machinery such as packaging, transfer, and indexing equipment. Integrated position feedback supports repeatable startups after power interruption, so the connected drive can restore axis location without a long reference routine. A standard housing supports use in typical industrial environments where compact servo motors must deliver accurate speed and position control across repeated duty cycles.

At standstill, the rotor can deliver 7.2 Nm of continuous torque, which allows the motor to hold a static load of that magnitude without exceeding its thermal limit. Once energized, it reaches a nominal speed of 4000 rpm, which is the expected synchronous operating speed under rated conditions. A blocking brake on the non-drive side supplies 11.0 Nm of holding torque to secure vertical axes when power is removed. Mechanical centering is achieved with a 110 mm pilot diameter that aligns the flange with mating fixtures. Power and feedback cabling exit on side B through a keyed circular connector, which keeps cable routing consistent when the motor is mounted against a machine plate.

Standard rotor balancing helps limit vibration, and the primary output end uses a plain shaft with a shaft seal to protect the bearing area. Motion data is returned through digital servo feedback, so the connected controller can maintain closed-loop speed and position accuracy during dynamic moves. The motor has frame size 090 and a B length code, giving it the mounting envelope associated with this housing family. A molded connector completes the electrical interface and supports a compact overall layout.
