Product Description:
The MSK070C-0300-NN-S1-UG0-NNNN is an AC servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This motor is intended for integration in industrial automation lines where quick acceleration, controlled speed, and exact positioning are required. When paired with a compatible drive controller, it converts commanded current into repeatable shaft torque for packaging, printing, and material-handling stations. Its synchronous design also supports rapid starts and stops on servo axes that must maintain stable motion during frequent indexing cycles.
Heat removal relies on natural convection, allowing the housing fins to dissipate losses without forced airflow. This keeps the cooling arrangement simple and avoids added fan hardware in compact machine layouts. Feedback is routed through a 240° rotatable connector, so the cable outlet can be aligned with surrounding machine constraints. The integrated encoder uses the Hiperface protocol, delivers 128 signal periods, and uses optical scanning to provide fine position data for high-resolution motion control. Because the measuring system is single-turn, the absolute position is reported for one mechanical revolution, and any multi-turn tracking must be handled in the controller. The motor is shipped without a holding brake, so external clamping or drive-torque retention is required when power is removed.
The motor uses frame code 070 and length class C, giving a moderate envelope that fits in compact axis modules without requiring an oversized mounting area. Winding code 0300 corresponds to the voltage constant and current rating expected by the drive, which helps the motor match the intended electrical operating range. Motion is transferred through a plain shaft, enabling backlash-free coupling with external gears or clamp hubs and supporting precise rotary transmission. The standard housing design, combined with passive heat dissipation, keeps installation straightforward in applications where active cooling is not preferred.
