Product Description:
The MSK070C-0450-NN-S1-UG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a rotary actuator for industrial automation, it converts drive current into controlled speed and torque so packaging, printing, and material-handling axes can follow precise motion profiles. A thermally isolated stator core helps manage internal heat during continuous operation, while an integral absolute encoder returns position data to compatible IndraDrive controllers. The electrically released brake holds the load when the machine is idle or powered down. This combination supports accurate motion control in applications that require repeatable starts, stops, and positioning.
Heat is removed by natural convection, eliminating the need for external fans when enough surrounding airflow is available. Because cooling is passive, the motor does not require separate fan power connections or forced-air hardware. The feedback connector is rotatable through 240°, giving several cable exit positions that help reduce bending stress during installation. Feedback signals are transmitted over Hiperface, which combines position data and electronic communication in one interface. Inside the standard-design frame, the 0450 winding code matches the motor’s electrical characteristics to typical 400 V DC-link applications, and the 70 mm frame diameter with the C-length package keeps the motor compact for continuous-duty use.
Position feedback uses an optical scanning method with 128 signal periods per mechanical revolution, allowing fine interpolation inside the drive. The encoder is single-turn, so it reports absolute position within one revolution and is well suited to axes that do not require multi-turn tracking. This feedback arrangement supports precise indexing and short-stroke positioning tasks without additional multi-turn electronics. When motion stops, the integrated brake provides 23 Nm of holding torque to prevent drift on vertical or suspended loads. Mechanical power is transmitted through a plain shaft, allowing the motor to be coupled with friction-clamp or keyed hub arrangements as required by the machine design.
