Product Description:

The MSK075D-0300-NN-M2-UG0-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. As an electrically commutated torque source, the unit couples directly to driven axes in packaging machines, pick-and-place gantries, and other automated equipment that require tightly controlled position and velocity loops. The combination of permanent-magnet excitation and integrated position feedback allows this motor to generate precise, repeatable motion while minimizing the need for additional mechanical transmission components in the drive train.

Its thermal management depends on natural convection, so enclosure mounting must allow unobstructed airflow around the stator housing. Position data are delivered through an optical measuring system that combines multi-turn absolute feedback with 2048 signal periods of incremental tracks, and this data stream is transferred to the controller through the EnDat2.1 digital interface. The feedback plug is rotatable through 240°, which eases cable routing in tight panels by allowing the connector to swing through an arc without twisting wires. Optical scanning provides strong immunity to magnetically induced jitter, and the multi-turn design preserves shaft position across power cycles without battery backup.

The motor uses a plain shaft interface that couples to standard clamp or keyless hubs without axial locating features. Frame code 075 corresponds to the stator diameter, while the D length extends the active core for the torque constant associated with winding code 0300. Increased concentricity machining keeps radial runout low, which helps reduce vibration when the motor is paired with high-resolution feedback. Because the unit is supplied without a holding brake, installations that must lock the load at standstill require an external clamping device or drive-based torque hold. The housing is drilled for panel mounting, and the encoder connector can still be swiveled after installation to relieve cable strain.
