Product Description:

The MDD090C-N-020-N2M-110GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where the controller closes the current, speed, and position loops for accurate axis motion. In machining centers, transfer systems, and material-handling equipment, the motor supplies controlled rotary power for repeatable movement under changing load conditions. Its size 090 geometry, standard housing, and standard balancing support installation in existing machine layouts, and the built-in centering pilot helps align the motor during mounting.

During operation, the motor delivers a continuous standstill torque of 10.4 Nm, which supports static holding and low-speed positioning at rated current. The centering pilot measures 110 mm, providing a consistent reference surface for machine mounting. A nominal speed of 2000 rpm supports moderate-speed applications that do not require additional gearing. Electrical terminations exit on the left side through a sealed connector, which helps route cables away from moving machine parts. Motion feedback is supplied through digital servo feedback (DSF), allowing the drive to monitor rotor position with high resolution. The shaft is present only on side A, leaving side B clear for internal components and the motor layout used by this series.

An integrated multiturn absolute encoder tracks full revolutions even when power is removed, so the control system can retain position information for a controlled restart. The motor is supplied without a blocking brake, so holding force at standstill must come from the drive system or the mechanical axis. The shaft exit includes a shaft seal, which helps protect internal parts from lubricant ingress and external contamination. Motor length code C increases the active stack length, which supports smoother running behavior and stable response during speed changes.
