Product Description:

The MDD071C-N-030-N5M-095PA0 is a synchronous servo unit manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it fits motor size 071 and has length code C. The device supplies rotational power to automated axes that require closed-loop speed and position control. It is delivered without a blocking brake, uses a standard housing, and relies on external drive functions for stopping and load holding when needed.

This model centers on a flange that measures 95 mm in diameter, allowing accurate alignment with gearboxes or machine frames. At stall, it can generate a continuous torque of 6.6 Nm, providing steady force for holding or slow-speed moves without overheating. Under rated electrical excitation, the rotor reaches a nominal speed of 3000 rpm, which suits applications that operate with common inverter outputs. Position and velocity data come from an integrated multiturn absolute encoder, and the multiturn function records revolutions so the controller retains shaft position after power loss. Feedback is transmitted as digital servo feedback (DSF), allowing high-resolution communication with compatible Indramat drive controllers.

Electrical terminations use a single connector that routes both power and signal lines, and all plugs face side A so cable routing remains consistent across the machine. The shaft has a keyway to help prevent slip between the motor and the attached coupling or pulley, and a shaft seal helps protect the internal bearings from coolant and dust. Dynamic imbalance is limited by standard balancing, which is suitable for the 071 frame and its operating speed range. The housing encloses the winding set, and the encoder signals support stable feedback processing during normal servo operation.
