Product Description:

The MDD071C-N-030-N2S-095PR0 is a synchronous servo motor built by Bosch Rexroth Indramat for use with digital drive controllers in the MDD Synchronous Motors series. As a rotary actuator, it converts electrical energy from the drive into controlled torque and speed for positioning axes, indexing tables, or transport modules within automated lines. It is intended for closed-loop motion systems that require repeatable positioning, smooth acceleration, and stable speed regulation during continuous machine operation. The motor suits applications that depend on accurate rotary response across frequent start-stop cycles.

At a nominal speed of 3000 rpm, the rotor can maintain rated velocity when supplied by a matched inverter without losing synchronization. During standstill, it can hold or start loads with 6.6 Nm of continuous torque, which helps with drive sizing and thermal evaluation. The motor has a centering flange of 95 mm, allowing direct seating into gearboxes or mounting fixtures with minimal radial runout. Position feedback is provided through digital servo feedback (DSF), enabling drive-controlled commutation and high-resolution motion loops. This feedback method allows the drive to monitor rotor position continuously during acceleration, deceleration, and steady-state operation. For applications that rely on external mechanical locks, the motor is supplied without a blocking brake, so no internal holding brake torque is available when power is removed.

Field connections exit on the right side through a single connector, which simplifies cable routing in compact cabinets. The C-coded body length pairs with the 071 frame size for inertia suited to mid-range point-to-point axes, and the shaft end is provided only on side A, which keeps the rear closed. A sealed shaft fitted with a keyway transmits torque, while the integrated shaft seal helps prevent lubricant migration and reduces the entry of contaminants at the output end. This layout works well in enclosed machine assemblies where protected shaft hardware and accessible cable routing are important.
