Product Description:

The MDD071C-N-040-N2T-095PR1 is a permanent-magnet synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied for use with digital drive controllers, it converts commanded phase currents into precise rotary motion for indexing tables, feed drives, and other automated axes. Its compact frame allows direct machine mounting, which helps reduce cable length and supports responsive motion control in space-limited equipment. The motor is intended for applications that require repeatable positioning, stable speed regulation, and dependable closed-loop operation during continuous industrial use.

At standstill, the motor sustains 6.6 Nm of continuous torque, allowing loads to be supported without external gearing when thermal limits are observed. During operation, the rotor reaches a nominal speed of 4000 rpm, enabling fast point-to-point moves with consistent stiffness. Accurate position data come from an integrated multi-turn absolute encoder, which preserves rotational information through power cycles and removes the need for a homing routine after restart. Power and feedback conductors exit on the right side through a single industrial connector, which helps simplify cable routing in compact machine layouts. Feedback signals use digital servo feedback (DSF), giving the associated drive the data needed for precise current, speed, and position control. The motor also uses a standard housing and standard dynamic balancing to support smooth running during continuous duty.

A blocking brake rated at 3.0 Nm holds the shaft whenever the controller is disabled, which helps secure vertical or suspended loads. The centering pilot of 95 mm aligns the stator accurately on the machine face, and frame code 071 matches the mounting pattern used for this motor size. Torque is transmitted through a shaft with a keyway, and a shaft seal helps limit contaminant entry into the bearing and encoder areas. The shaft is finished only on side A, so the rear of the motor remains closed. Length code C provides additional active copper while keeping the motor within a compact installation envelope.
