Product Description:

The MDD090B-N-030-N2L-110GA2 is an AC synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded stator current into precise mechanical rotation for industrial positioning tasks. Its permanent-magnet rotor and electronic commutation support fast response and repeatable accuracy in pick-and-place gantries, packaging stations, and machine-tool feed axes. This type of motor is commonly used where smooth acceleration and accurate stopping are required over short cycle times. Its closed-loop operation helps the connected drive maintain stable motion even when the load changes during a run.

It supplies a continuous standstill torque of 7.2 Nm, so the axis can hold load without overheating while stationary. When accelerating, the rotor can reach 3000 rpm, a nominal speed that suits many Indramat drive combinations used for positioning duty. An integrated blocking brake produces 11.0 Nm of holding force once power is removed, which helps secure vertical or suspended mechanisms. Position data is returned through Digital servo feedback (DSF), providing high-resolution signals for closed-loop speed and position control. A plain shaft extends from the frame and mates with clamping hubs or couplings for direct power transmission.

A centering pilot of 110 mm matches standard Rexroth flange patterns and helps maintain concentric alignment with gearboxes or machine interfaces. Power and feedback leads exit on Side A, and the single plug-in connector keeps cable routing compact around the motor. The motor includes a shaft seal, which helps keep lubricant or cutting fluid out of the bearing cavity during operation. Frame code 090 identifies the motor size, and length code B is used with standard balancing, a standard housing, and a connector interface. The motor uses a single-ended shaft layout.
