Product Description:

The MDD071C-N-040-N2T-095GL2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and included in the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies closed-loop rotary motion for positioning axes and general automation tasks on packaging lines, machine tools, and material-handling systems. Its permanent-magnet design allows the controller to regulate speed and torque precisely over repeated start-stop cycles, making it suitable for applications that require high cycle rates and repeatable accuracy.

The motor has a size code of 071 and a length code of C, which gives it an active stack height that supports a continuous stall torque of 6.6 Nm. Under rated excitation, the rotor reaches a nominal speed of 4000 rpm, giving mid-power axes a broad operating range. The centering collar measures 95 mm in diameter, and standard balancing helps limit residual vibration during direct coupling to precision loads. Power and feedback cabling exit on the left side through a keyed connector, which can simplify routing in multi-axis machines. The housing follows the standard chassis used across the series, and the plain shaft geometry supports hub-clamp couplings without keyway-induced stress.

A blocking brake rated at 6.5 Nm holds the shaft when the drive is disabled, helping prevent position drift on vertical or inertial loads. Position data is provided by an integrated multi-turn absolute encoder, and the drive reads this information through Digital Servo Feedback (DSF) so the position loop can close without external transducers. A factory-installed shaft seal helps maintain the motor's IP protection during washdown or oil-mist exposure. These features allow the motor to retain position information after power cycling while also supporting controlled stopping when the axis is not energized.
