Product Description:

The MDD071A-N-040-N2T-095PL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated three-phase current into controlled torque and speed for closed-loop positioning tasks. It is used in industrial automation equipment such as packaging machines and electronics assembly systems where repeatable motion, compact installation space, and continuous operation are required. The motor uses frame size 071 with length code A, which helps it fit tightly spaced axis layouts without moving into a larger housing class.

The motor delivers a continuous standstill torque of 2.2 Nm, giving the axis holding capability during low-speed operation. Under rated excitation, it reaches a nominal speed of 4000 rpm, which supports short cycle times when the driven load has moderate or low inertia. Accurate mechanical alignment is supported by a centering diameter of 95 mm, and standard dynamic balancing helps reduce vibration during rotation. Power and feedback cables leave through the left-side cable exit, and connection is made through an industrial connector that keeps wiring secure in compact machine spaces. The motor also uses a standard housing and includes a shaft seal to help keep lubricant inside the assembly during high-speed operation.

Position data are returned through digital servo feedback (DSF), which works directly with the drive control loop for precise speed and position regulation. A built-in integrated multi-turn absolute encoder retains absolute shaft position after power is removed, so the control system can recover position information without a new reference cycle. For vertical axes, a blocking brake rated at 3.0 Nm holds the rotor when commanded torque is absent. The brake is spring applied and releases electrically, so no external actuator is needed for normal holding operation. Torque is transmitted through a single-ended keyway shaft, and there is no second shaft extension on side B, leaving only one output end for the mechanical connection.
