Product Description:

The MSK071E-0300-NN-S2-UP1-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit converts drive current into accurately controlled torque and speed for positioning tables, pick-and-place arms, and packaging spindles. Integrated feedback hardware supplies real-time shaft data to IndraDrive controllers, so the motor supports high-precision motion loops in industrial automation cells. Its compact layout combines the motor body and feedback system in one assembly, which helps reduce external components around the axis.

This motor relies on natural convection for thermal management, so heat leaves the housing through its aluminum surface without fans or liquid circuits. To supply the drive with position data, the unit uses an encoder that communicates via EnDat2.1, a digital interface that supports automatic parameter transfer together with incremental and absolute signals. The optical reader generates 2048 signal periods per mechanical turn, allowing fine interpolation inside the controller for smooth speed regulation and precise position tracking. A field-wiring benefit is the encoder plug, which is rotatable through 240° and allows the cable to exit in several directions after installation. Because the sensing principle is optical, nearby magnetic fields do not disturb the position signal, which helps maintain stable feedback quality in compact machine layouts. The increased-concentricity option also reduces radial runout at the shaft, which is useful in applications that depend on repeatable rotation.

The encoder is a single-turn device, so it reports the absolute shaft angle within one revolution and relies on the drive for multi-turn counting. An electrically released holding brake provides 23 Nm of static torque, allowing the axis to remain in place during shutdown or while power is removed. Torque is transmitted through a shaft with a keyway, a common coupling arrangement for pulleys, pinions, and gears. The 071 frame size sets the motor envelope, while length grade E provides the stack depth used with the 0300 winding. This layout suits machines that need accurate motion control without forced cooling or a separate external feedback package.
