Product Description:

The MDD090B-N-030-N2M-130GR2 synchronous servo motor is produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled current into accurate rotary motion for industrial positioning, feed, and indexing axes. The unit uses the 090 frame size and B length designation, giving it a familiar mounting format in machinery that already accepts this motor size. Because it is intended for closed-loop servo operation, it is suited to applications that require repeatable motion and stable speed response during frequent starts and stops.

At standstill, the motor supplies 7.2 Nm of continuous torque, which helps support loaded axes without overheating. Under commanded operation, it reaches 3000 rpm, making it suitable for direct coupling to ball-screw or timing-belt transmissions. A built-in blocking brake delivers 11.0 Nm of holding torque, maintaining axis position when power is removed. The centering flange has a diameter of 130 mm for accurate alignment to a gearbox or machine plate. Position feedback is generated by an integrated multi-turn absolute encoder, so the axis does not require a homing routine after each power cycle. This allows the controller to retain shaft position information across multiple revolutions after a stop or restart.

Rotor mass is stabilized by standard balancing, which helps reduce vibration during rotation. All power and feedback leads terminate in a single connector that exits to the right, which can simplify cable routing in narrow enclosures or along machine sidewalls. Feedback signals are delivered as Digital servo feedback (DSF), providing high-resolution velocity and position data to the drive during closed-loop operation. The motor also uses a plain shaft with a shaft seal, a standard housing, and no side-B shaft extension.
