Product Description:

The MDD090B-N-030-N2L-130PA1 is a permanent-magnet synchronous servomotor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it receives regulated three-phase current from an Indramat drive and turns it into tightly governed shaft rotation. The device is installed on individual axes of assembly machines, packaging stations, and material-handling gantries where repeatable torque and quick speed changes are required for process synchronization. Its compact frame and keyed shaft let it couple to gearboxes or belt pulleys without adding intermediate couplings.

At standstill, the motor can deliver a continuous 7.2 Nm of torque without exceeding its thermal limits, while its nominal speed is 3000 rpm under balanced load. A centering diameter of 130 mm permits accurate location on mounting flanges and supports a standard balancing grade that minimizes residual vibration across the speed range. Frame code 090 and length code B indicate the physical envelope and winding arrangement, and the standard housing allows convection cooling inside closed cabinets. Command and feedback signals are exchanged through a connector interface, and position information is returned by the integrated digital servo feedback system, enabling high-resolution current loops in the associated drive. The shaft end is supplied in the standard single-ended form, ready for external couplings.

For load-holding duties, a blocking brake is fitted and supplies 6.5 Nm of static torque when the drive is de-energized. Power, brake, and sensor leads exit on side A, simplifying cabinet routing when the motor is mounted in tight spaces. Contaminant ingress at the shaft is limited by a fitted shaft seal, and the output journal is machined with a keyway to transmit torque without slip to gears or pulleys.
