Product Description:

The MDD090B-N-030-N2L-130GR0 is a servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As an electronically commutated AC unit, it converts drive controller commands into precise rotary motion for positioning, indexing, and continuous-duty tasks on automated axes. Used together with digital drive controllers, the motor supplies repeatable torque, speed, and feedback so that machine tools, packaging lines, and material-handling equipment can keep cycle times consistent. This arrangement lets the paired controller regulate axis motion accurately during starting, running, and stopping.

The motor has a nominal speed of 3000 rpm. A continuous standstill torque of 7.2 Nm shows how much load the shaft can hold indefinitely without overheating while locked. The motor centers on a 130 mm pilot, which helps align it concentrically with gearboxes or mounting plates. Power and encoder leads exit on the right side, which can shorten cable routing when the drive cabinet is placed on that side of the machine. A single connector carries the power phases and protective earth. Integrated digital servo feedback (DSF) provides high-resolution position information so the controller can correct position error within each electrical cycle. The motor is supplied without a blocking brake, so vertical axes require an external holding method.

Standard balancing helps keep residual vibration low during high-speed operation. Frame size 090 sets the outside diameter and bolt circle for this motor class. The plain shaft is supplied with a shaft seal, which helps prevent lubricant or coolant from entering the stator cavity during oil-splash or washdown service. A standard housing and the absence of a secondary shaft end reduce the overall envelope while maintaining torsional stiffness in compact machine layouts.
