Product Description:

The MDD071B-N-030-N2S-095PL2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts regulated current from a servo amplifier into precise rotary motion for packaging machines and similar positioning axes. Integrated closed-loop feedback allows accurate speed and position control during repeated motion cycles. Its compact frame suits machine layouts that need a short motor body while still supporting responsive servo operation.

The motor delivers a continuous standstill torque of 4.4 Nm, allowing the axis to hold static loads without exceeding normal thermal limits. During motion, it reaches a nominal speed of 3000 rpm, which supports fast indexing in compact production cells. A factory-installed blocking brake provides 6.5 Nm of holding torque so suspended loads can remain fixed when power is removed. Mechanical centering is provided by a 95 mm pilot on the front flange, and position data are returned through digital servo feedback (DSF) for closed-loop accuracy within the associated controller. The flange pilot helps seat the motor accurately against the machine face, and the rotor is balanced to a standard grade to reduce vibration during operation. The standard housing does not use auxiliary cooling fins.

All service interfaces are located on the left side, where a single connector carries power, brake, and feedback conductors to simplify cable routing. The output shaft uses a keyway for positive mechanical locking and is supplied with a shaft seal to help protect the internal bearings from dust and splash. A keyed shaft supports secure torque transfer to hubs, pulleys, or similar driven parts. The motor has a single shaft end on the drive side, leaving the rear face clear for close coupling to gearboxes or belt-driven components. This arrangement can reduce the space needed behind the motor in tightly packed axis groups.
