Product Description:

The MSK075C-0300-NN-S3-UG0-NNNN belongs to the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. Classified as an IndraDyn S synchronous servomotor, it converts drive-controller current into controlled rotary motion for positioning tables, pick-and-place modules, and other automated equipment that require repeatable torque and speed. Integrated feedback and a brushless rotor support high cycle counts with minimal wear, making the unit suitable for multi-axis production lines. The brushless design also helps the motor handle frequent acceleration and deceleration during repetitive motion tasks.

The motor is cooled by natural convection, eliminating external blowers and reducing service points in tightly enclosed panels. An IP65 enclosure blocks dust and low-pressure water jets from reaching internal components. The plain shaft provides a smooth coupling surface for backlash-free connections to gearboxes or pulleys. Motion data travels through a Hiperface link that combines incremental channels with absolute position from a capacitive transducer calibrated to 16 signal periods per revolution. This arrangement gives the drive both commutation data and absolute position information through the same feedback path. Because no external blower is required, surrounding components do not need clearance for a separate cooling unit. Wiring is simplified by the 240° rotatable encoder connector, which lets the harness exit in the preferred direction without twisting the cable.

The mechanical format follows motor size 075, length code C, and winding code 0300, giving the motor characteristics suited to mid-range servo axes in handling, packaging, and synchronized transfer applications without unnecessary inertia. The C length provides additional active motor length within the same frame size. Because this variant ships without a holding brake, the axis must rely on drive-based torque or an external clamp to hold position when power is removed. The single-turn feedback architecture reports position across one mechanical turn, which suits fast indexing applications that return to a known angular reference. Thermal headroom is supported by insulation class 155, and continuous duty is permitted within an ambient range of 0–40 °C.
