Product Description:

The MSK071D-0300-NN-M2-UG2-RNNN is a synchronous servo motor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S device, it converts electrical input from a servo drive into precise rotary motion for positioning tasks in industrial automation, including packaging axes and pick-and-place gantries. The motor supports highly repeatable motion sequences required by modern assembly lines. In typical use, it works with a matched servo controller to provide controlled acceleration, stable running speed, and accurate stopping at commanded positions.

This motor uses natural convection for cooling, so the housing dissipates heat directly to ambient air without forced airflow. The mechanical design features increased concentricity, which reduces runout and helps keep coupling loads low during rotation. An electrically released holding brake supplies 30 Nm of static torque to secure vertical loads when power is removed. For flexible cabinet wiring, the feedback plug is rotatable through 240°, and it carries position data through the EnDat 2.1 serial interface to the drive controller. That connector arrangement helps when the motor is installed in confined spaces or where cable routing must avoid nearby machine members.

High positioning fidelity is achieved with an optical encoder that produces 2048 signal periods per revolution. Its optical scanning method minimizes drift, and the encoder provides multi-turn absolute feedback so the shaft angle is retained across power cycles. This allows the control system to keep track of rotor position without relying only on incremental counting during operation. Power is transmitted through a plain shaft, which simplifies coupling to gearboxes, pulleys, and clamp-style hubs. The motor belongs to size 071 with length code D and uses the 0300 winding set for this frame.
