Product Description:

The MSK070C-0450-NN-S1-UG0-NSNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts drive power into precise rotary motion for positioning tables, packaging axes, and similar automation tasks that require closed-loop speed and torque control. When paired with a suitable servo drive, it supports responsive acceleration, accurate position control, and repeatable motion in automated machinery. It is intended for installations that may include both standard areas and zones requiring explosion protection, allowing one motor type to be used across mixed plant areas.

The motor has a frame size of 070 and a length class of C, which indicate its mechanical envelope for compatible gearboxes or mounting flanges. The housing dimensions also affect available mounting space and coupling selection in the machine layout. Electrical characteristics are matched to compatible drive inverters through winding code 0450, which indicates the phase resistance and inductance values used for stable current regulation. Heat is removed by natural convection, so the motor relies on its surface area and surrounding airflow without auxiliary fans. A sealing system rated at IP65 blocks dust and low-pressure water jets, allowing installation near machining coolant or wash-down areas. The thermal insulation class 155 supports winding temperatures suited to Class F materials, and the design without an integral brake reduces inertia when fast acceleration is required.

The feedback system uses a Hiperface interface that communicates absolute position data from an optical sensor with 128 signal periods per mechanical turn. This feedback arrangement lets the connected controller track rotor position for commutation and closed-loop motion control. The encoder connection can be rotated 240°, which simplifies cable routing in tight enclosures, and operation is specified between 0–40 °C. Torque is transmitted through a plain shaft, which is suited to direct connection with external couplings or pulleys selected for the application. The absence of a holding brake allows free coasting when power is removed while minimizing residual drag on high-speed axes.
