Product Description:

The MDD071B-N-030-N2S-095PL0 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. In automated machinery, this unit serves as a torque source for digital drive controllers, providing closed-loop motion in pick-and-place axes, packaging stations, and other cyclic equipment. Its 071 frame size and B length code place it in the medium power range of the series, while the standard housing and internal balancing allow mounting without additional vibration treatment. The synchronous design supports accurate response to commanded current, which is useful where axes must start, stop, and reverse repeatedly without losing position stability. The motor is suited to applications that require repeatable motion over frequent start-stop cycles.

At the mechanical interface, the centering pilot measures 95 mm, ensuring concentric alignment with gearbox or machine plates. Electrical and feedback conductors exit on the left side through a sealed connector, which can simplify cable routing in tight cabinets. Because power and feedback leave from the same side, surrounding machine members can be kept clear of moving cable loops and rear overhang. The motor develops 4.4 Nm of continuous standstill torque, so it can sustain load while held in position by the drive. Under rated excitation, the rotor reaches 3000 rpm, giving a broad operating range for indexing and transfer tasks. Position data are returned by the integrated digital servo feedback (DSF) encoder, permitting high-resolution commutation and diagnostic tracking through the controller.

The shaft has a keyway and a fitted shaft seal to keep lubricant inside the bearing chamber. A keyed shaft allows torque transfer through standard hub connections used on pulleys, pinions, or couplings. The motor uses a single-ended shaft without a side B extension, which reduces overall length and leaves rear space for the connector block. Because the motor is supplied without a blocking brake, any hold torque during power loss must be provided by an external device or the drive itself. Standard dynamic balancing and frame code 071 support installation with compatible digital drive controllers.
