Product Description:

The MDD071B-N-030-N2T-095PL2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers where rapid positioning and regulated velocity are required in automated machinery, material-handling axes, and packaging equipment. Its synchronous design supports precise speed regulation and repeatable motion during frequent starts, stops, and direction changes. In this role, the motor converts controlled current into rotary motion for indexing, feed, and transfer tasks where response accuracy matters throughout the cycle. Connections exit on the left side through a circular power and feedback connector, simplifying cable runs in cabinets laid out with right-hand busbars.

This model supplies a continuous standstill torque of 4.4 Nm, allowing it to hold loads without motion while current remains within the drive limits. During operation it can reach a nominal mechanical speed of 3000 rpm, supporting direct coupling to gearless loads and other common servo axis duties. That speed range suits many packaging and handling applications that rely on direct motor coupling or compact gear stages. For emergency or power-off retention, the integrated blocking brake delivers 6.5 Nm of static torque. The brake supports load retention when supply power is removed, which is useful on axes that must remain in place at standstill. Mechanical alignment in mounting fixtures is guided by a centering diameter of 95 mm, and the overall frame designation is motor size 071. The motor length code B, standard housing, and standard dynamic balancing keep rotor mass moderate while limiting vibration at rated speed.

The feedback channel uses Digital servo feedback (DSF) generated by an integrated multiturn absolute encoder, so the controller can recover rotor position after power cycling without a homing move. A keyway shaft end supports positive coupling to pulleys or hubs, and a shaft seal is fitted to help keep lubricants or coolants from tracking along the journal into the stator cavity. This arrangement supports reliable torque transmission while helping protect the front bearing area during normal machine operation. The motor uses a single-ended shaft, which reduces overhung mass on the bearings. The connector interface supports the standard pin assignments used by Indramat drives, which helps keep electrical integration straightforward in multi-axis servo assemblies.
