Product Description:

The MDD071C-N-040-N2S-095GR2 synchronous servo motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it provides rapid acceleration, repeatable positioning, and continuous-duty motion in automated equipment such as pick-and-place stations or light machining spindles. The housing follows the series standard cooling and mounting format, and internal dynamic balancing at the standard grade limits vibration transmitted to the machine frame. When paired with a suitable drive, the motor maintains commanded velocity during changing load conditions and supports stable axis response in repetitive motion tasks.

Its nominal shaft speed reaches 4000 rpm, indicating the maximum continuous rotational velocity available at rated operating conditions. At standstill, the motor can deliver a continuous torque of 6.6 Nm, allowing low-speed moves and holding duty without excessive heating. The centering pilot on the flange measures 95 mm, which provides a precise reference surface for concentric mounting to the machine interface. Power and feedback leads exit on the right, and a detachable connector provides a compact electrical interface while simplifying cable removal. A shaft seal protects the internal bearings from contamination, and the standard housing relies on ambient airflow for heat dissipation rather than an integrated blower.

Position retention during power loss is handled by a blocking brake that supplies 6.5 Nm of static torque, allowing suspended loads to remain stationary when the inverter is de-energized. Motion feedback is produced by a DSF encoder, which sends digital position data to the controller for commutation and closed-loop operation. The frame designation 071 and the length code C set the motor envelope for moderate inertia applications where compact installation space is still important. Drive torque reaches the load through a plain shaft that omits keyways and side-B extensions, which helps reduce runout sources and simplifies coupling alignment.
