Product Description:

The MDD090C-N-040-N2M-130PB2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical power into rotational motion for positioning tasks in automated machinery. Within a closed-loop drive, this unit supplies the commanded torque and speed needed to move mechanical loads with repeatable accuracy. This type of motor is commonly used on feed axes, transfer units, and other motion systems where stable response and accurate feedback are required during continuous operation.

The motor’s nominal speed reaches 4000 rpm, allowing rapid cycle times when paired with a compatible inverter. At standstill, it can hold a load with 10.4 Nm of continuous torque, while a blocking brake delivers an additional 11.0 Nm of static holding force when power is removed. A centering diameter of 130 mm provides the locating fit on the mounting surface and helps keep the motor aligned with the driven axis. Power and feedback conductors exit on Side B, which can simplify routing when space near the opposite face is limited. This arrangement supports compact machine layouts and keeps the cable connection clear of adjacent mechanical components.

Signal exchange relies on Digital servo feedback (DSF) combined with an integrated multi-turn absolute encoder, enabling the controller to read position without a homing move after power-up. Torque is transmitted through a keyway on the shaft, and contamination is restricted by a design with a shaft seal that helps limit lubricant migration into the housing. A molded connector provides the electrical interface, and standard balancing helps keep residual vibration within normal operating limits. The C length code matches the stack height used for this motor version, while the 090 frame size suits medium-power axes. The housing uses a single-ended shaft, which supports direct coupling to gears or belt pulleys without a second shaft output on side B.
