Product Description:

The MSK075C-0300-NN-S1-UP0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated equipment, it transforms drive current into controlled rotary motion, enabling precise axis positioning and repeatable velocity profiles. Mechanical and electrical interfaces are matched to IndraDrive power stages, so the motor can be integrated into packaging machinery, pick-and-place units, or general-purpose machine tools where compact, high-performance motion is required.

Heat is removed through natural convection, eliminating external fans and allowing the motor to retain an IP65 housing that resists dust and water jets. A keyed shaft couples torque directly to transmission elements, and the 075 frame with length C fits mid-range load requirements while keeping axial space minimal. Feedback is routed through a 240° rotatable connector that links to a Hiperface scanner. This encoder resolves rotor angle across 128 signal periods, and its optical pickup tracks a coded scale without physical contact, which helps reduce wear over time. Because the unit is supplied without a holding brake, external locking devices are needed when power-off position retention is critical. The motor uses a standard design and insulation class 155 to tolerate elevated winding temperatures during continuous duty.

The encoder is single-turn, so it delivers an absolute position within one mechanical revolution and suits axes that re-reference at startup. Operation is limited to an ambient temperature range of 0–40 °C, so surrounding airflow must keep the housing within that range during continuous use. Drive configuration relies on winding code 0300, which sets the resistance, inductance, and permissible current for use with a matching power module.
