Product Description:

The MDD090C-N-020-N2M-110PR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Created for digital drive controllers in automated machinery, it translates commanded current into precise rotary motion for positioning tables, pick-and-place axes, and similar duty cycles. A size-090 frame with a C-length housing supports the stator, and the integrated blocking brake minimizes auxiliary hardware. All power, signal, and brake leads terminate through a single right-side connector, allowing the motor to be mounted close to adjacent actuators without excess cabling.

The motor can deliver a continuous standstill torque of 10.4 Nm without exceeding thermal limits, and it reaches a nominal operating speed of 2000 rpm when supplied with rated voltage and frequency from the inverter. A standard rotor balancing grade keeps vibration within limits for long bearing life, while the centering pilot measures 110 mm, giving a rigid locating surface on mounting flanges. During cycle interruptions, the integrated brake supplies 6.5 Nm of holding torque to secure vertical or load-bearing axes. The shaft end uses a keyway profile so drive elements can transmit torque without slip. A standard housing and the C-length code set the thermal mass and envelope size, making the unit compatible with cabinets that already accommodate other 90 mm family motors.

Cabling faces the operator side, and the plug-in digital servo feedback (DSF) channel returns high-resolution position data to the drive. An integrated multi-turn absolute encoder maintains position through power loss, eliminating homing sequences at startup. Environmental ingress is limited by a shaft seal, while the standard housing and shaft-end configuration without a side-B extension keep overall length short. Connector-style terminations keep wiring straightforward for motion systems that require moderate torque and closed-loop accuracy.
