Product Description:

The MDD071B-N-040-N2S-095PL2 is a servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it supplies controlled rotary motion for positioning, tracking, or speed-regulated tasks in automated machinery. The motor’s design supports compact multi-axis layouts in packaging lines, handling cells, and light machining where synchronized operation is required. Its synchronous construction also supports repeatable acceleration and accurate stopping in axes that must maintain consistent motion from cycle to cycle.

The rotor is balanced to a standard grade to minimize vibration, and the flange carries a centering diameter of 95 mm for precise seat location. Electrical and feedback terminations are routed on the left side through a single connector, simplifying cable runs inside a cabinet. At standstill, the motor can deliver 4.4 Nm of continuous torque, while its electromagnetic design allows rated operation up to 4000 rpm. A blocking brake is integrated; it clamps the shaft with 6.5 Nm of holding torque to secure vertical or intermittent-duty axes when power is removed. Motion data are returned through digital servo feedback, enabling the drive to close position and velocity loops without external encoders. A standard housing encloses the stator windings, and length code B gives the overall body depth for this motor version.

Frame size 071 places the motor in a compact stator class, and the output shaft is machined with a keyway for standard couplings and hubs. A fitted shaft seal limits lubricant escape and helps block airborne moisture and contaminants. The motor uses a single shaft end rather than a second stub on side B, which helps conserve installation space where rear clearance is limited. This arrangement suits machine layouts that place the motor close to covers, brackets, or neighboring axes.
