Product Description:

The MSK071E-0303-NN-S1-UG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Intended for tight position and speed regulation, it serves as a direct-drive element in automated packaging lines, material-handling stations, and coordinated multi-axis systems where precise rotary motion is required. The combination of size code 071 and motor length E gives the motor its frame and active stack length. When paired with a compatible drive, it supports controlled acceleration, deceleration, and accurate speed holding during repeated motion cycles. This makes it suitable for indexing axes, conveyors, and synchronized handling units that rely on repeatable rotary positioning under changing loads.

Heat generated in operation is removed by natural convection, allowing installation without fans or liquid circuits. The housing carries an IP65 protection rating that helps keep dust and water jets away from internal components, and the mechanical execution is standard with no special mounting deviations. Power is transmitted through a plain shaft, and no integrated brake is fitted, so external holding devices are required when static load support is needed. Position data is transmitted over the Hiperface interface, and the optical measuring element reports absolute position within a single mechanical revolution. That single-revolution capability is identified by the encoder's single-turn designation, which allows position availability after power restoration.

The feedback connector can be oriented through a rotatable, 240° arc, giving more flexibility when routing cables in tight enclosures. Inside the encoder, an optical scale generates 128 signal periods per turn, and the drive controller interpolates these periods for fine incremental control during motion. The motor operates within an ambient range of 0-40 °C, and its winding insulation is rated to class 155 for continuous service at elevated internal temperatures. The adjustable connector position can also reduce cable twist where the motor is mounted close to panels or guards. This insulation class supports steady operation when internal motor temperatures rise during long production runs.
