Product Description:

The MDD090C-N-040-N2M-130GL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit converts electrical energy into precise rotary motion. This supports positioning tables, filling lines, and packaging axes inside automated machinery. The design is suited to applications that require accurate speed and position control over repeated operating cycles.

The motor reaches a nominal speed of 4000 rpm, allowing fast indexing cycles while maintaining closed-loop regulation. At standstill it can hold a load with 10.4 Nm of continuous torque when the axis must resist static process forces. A spring-applied blocking brake supplements this by delivering 6.5 Nm of mechanical holding torque whenever power is removed. Rotor balance follows a standard grade to minimize vibration, and the centering pilot is machined to 130 mm so the frame aligns accurately on machine mounting surfaces. Position feedback is supplied through digital servo feedback (DSF), enabling the drive to detect motor angle without additional sensors. The cast-aluminum housing is the standard enclosure variant and is fitted with a shaft seal that restricts oil or coolant ingress at the output end.

Power and encoder conductors exit on the left side through a keyed connector, simplifying cable routing in multi-axis cabinets. Motion is transmitted by a plain shaft in the standard single-ended configuration, without a secondary shaft on side B, which reduces overall length. The integrated multi-turn absolute encoder counts several revolutions, so absolute position is retained after shutdown. This arrangement helps preserve machine position after a restart without a reference move. Size code 090 and length code C indicate the stator dimensions used for inertia matching or gearbox selection. The motor uses a standard balancing class and standard housing finish, and it includes a shaft seal for general-purpose industrial environments.
