Product Description:

The MDD071C-N-040-N2T-095GA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers in material handling stations, packaging machinery, and other automated assemblies where compact size and accurate torque delivery are important. By combining an internal position sensor with electronic commutation, the unit converts drive current into controlled mechanical motion that follows high-speed command profiles. This arrangement supports stable closed-loop operation during positioning, indexing, and repeated speed changes.

At standstill, the rotor can deliver 6.6 Nm of continuous torque, providing static load capacity and closed-loop stiffness. During operation, the winding set supports a nominal speed of 4000 rpm. A centering pilot of 95 mm aligns the flange accurately with gearbox or machine brackets, and standard dynamic balancing helps reduce residual vibration at rated speed. Position information is produced by an integrated multiturn absolute encoder and routed through Digital servo feedback (DSF) channels. Power and signal conductors pass through a single connector, which simplifies cabinet wiring. The motor includes a shaft seal to limit the ingress of coolant or process dust, but it is supplied without a blocking brake, so any holding function must be provided by the drive or an external clamp.

Electrical terminations exit on side A, which helps route cables away from adjacent axes when the motor is installed in its standard orientation. The length designation C pairs with the frame size 071 and corresponds to the housing length and thermal mass used for this torque class. The output uses a plain shaft on the drive side only, so torque is transferred through an external coupling. This arrangement suits clamped or keyed hub components selected for the machine. The shaft seal also helps protect the bearing area from contamination during normal industrial use.
