Product Description:
The MDD090B-N-030-N2L-110PA2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts precisely regulated electrical power into rotary motion for automation axes that require accurate speed and position control. The motor has length code B and uses the series' standard housing for mounting on machine structures or open frames. It is suited to packaging, transfer, and machining systems where repeatable motion and stable closed-loop response are required. Its operating role is to follow current commands from the drive while the feedback loop corrects load-related errors in real time.
This model reaches a nominal speed of 3000 rpm when paired with its designated inverter, providing a common operating range for positioning tasks. At standstill, the motor delivers 7.2 Nm of continuous torque, while the integrated blocking brake supplies 11.0 Nm of holding torque when power is removed. A centering diameter of 110 mm aligns the flange with adjoining machine plates and helps keep the shaft centered during installation. Position information is returned through digital servo feedback (DSF), which gives the controller high-resolution data for closed-loop regulation across the speed range. This arrangement supports both controlled motion during operation and secure holding at rest.
The output shaft uses a keyway so torque can be transferred through keyed couplings, and all conductors exit on side A to simplify cable routing. A molded connector combines motor power, brake, and feedback contacts in one plug, which reduces the number of separate cable terminations at the motor. A shaft seal is installed at the factory, and the shaft is present only on the drive side, so there is no rear shaft extension. The single-sided shaft layout also keeps the non-drive end compact, which helps when the motor is installed near guards or machine panels. Frame size 090 balances power density with installation space, and the housing finish resists oil mist and airborne dust common in machining cells.
