Product Description:

The MDD093C-N-020-N2M-130GR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers commanded torque and velocity directly to mechanical loads while its internal sensors return position data to the drive. This closed-loop arrangement allows the controller to correct motion deviations during operation. It can be used in machinery where repeated acceleration, stopping, and accurate positioning are required over continuous duty cycles.

The motor is rated for a nominal speed of 2000 rpm, allowing steady operation when the drive provides the corresponding synchronous frequency. A centering diameter of 130 mm aligns the housing with mounting adapters and helps keep radial runout within normal limits for this model. An integrated blocking brake can apply up to 22 Nm of static holding torque to secure vertical loads when power is removed. Power, brake, and feedback conductors exit on the right side through a sealed connector. Rotor position is measured by an integrated multiturn absolute encoder, so the drive can read the shaft angle immediately after startup. This feedback arrangement supports position retention across power cycles and reduces the need for homing after restart.

A plain shaft transfers torque directly to couplings without the added mass of keyways. Feedback to the controller uses Digital servo feedback (DSF), which carries position, speed, and diagnostic data through one high-resolution channel. The motor is supplied with a shaft seal, which helps limit contaminant ingress at the output end when the unit is correctly installed. The motor uses frame size 093 and length code C, giving it a predictable installation envelope. The housing uses the standard geometry for this frame, which helps the motor fit common mounting spaces in existing machine layouts. The shaft end remains standard without a side-B extension, and electrical terminations use the prescribed connector format for easy disconnection.
