Product Description:

The MDD090C-N-020-N2M-110GA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts commanded electrical power into precise mechanical rotation for closed-loop motion axes in industrial automation. The unit suits applications that need moderate inertia and accurate positioning in packaging, material handling, and gantry modules. Its synchronous design supports stable response during repeated start-stop cycles and controlled speed changes.

Mechanical interfaces follow a standard balancing grade to reduce residual vibration, and the mounting pilot has a 110 mm centering diameter that aligns the motor flange with the driven machine. A plain shaft exits the housing, and power and feedback cables are routed through the Side A connection face by means of a connector plug system, simplifying cabinet harnessing. Rated continuous torque at standstill reaches 10.4 Nm, allowing the axis to sustain load without overheating when locked. Under rated excitation, the rotor reaches a nominal speed of 2000 rpm, which suits medium-speed indexing drives and general positioning duties.

Position information is provided by an integrated multi-turn absolute encoder, which feeds digital servo feedback signals to the drive for real-time correction of velocity and angle. The C length designation pairs the 090 frame size with a stator stack long enough to deliver the listed torque while maintaining a standard housing outline. Because the motor is supplied without a blocking brake, motion retention during power-off must be provided by external means. The output uses a plain shaft that mates directly with couplings, and a shaft seal is fitted to help keep dust and coolant away from the shaft bore. The sealed shaft passage helps protect the bearing area in installations where splash or airborne debris is present.
