Product Description:

The MDD090B-N-020-N2M-130PR0 is a synchronous servo motor built by Bosch Rexroth Indramat and placed within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts controlled three-phase power from an Indramat drive into precise mechanical rotation for positioning, indexing, or speed-regulated axes on automated machinery and production lines. Its B-length housing and 090 frame size fit mid-range mechanical envelopes common to packaging, printing, and material-handling equipment. The motor is suited to applications that need repeatable motion, stable servo response, and compact installation space.

At standstill, the motor can deliver 7.2 Nm of continuous torque, allowing it to hold loads without motion while the control loop stays energized. During dynamic operation, it reaches a nominal speed of 2000 rpm, which is the reference velocity used when sizing gear ratios and drives. Accurate alignment to the machine is simplified by a centering pilot of 130 mm. The cable glands are oriented to the right, which supports common side-A cable routing in compact machine layouts. Power, feedback, and brake leads terminate on a single connector. Standard balancing limits residual vibration, and the housing dissipates heat through convection.

The integrated multi-turn absolute encoder supplies position data through power cycles, allowing homing-free recovery after power loss. That signal is sent as digital servo feedback (DSF), matching Indramat controllers that expect high-resolution status words. Torque is transmitted through a shaft with a keyway, and no side B extension is present, which keeps the motor shorter at the rear. The shaft end is fitted with a shaft seal, which helps keep coolant mist or dust away from the front bearing. Because the motor ships without a blocking brake, external holding must be used on vertical axes or whenever the load must remain fixed after power is removed.
