Product Description:

The MSK070D-0300-NN-S1-UG0-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. It converts electrical power from a compatible drive into controlled torque and speed for automated machine tools, packaging lines, and assembly stations. By integrating high-resolution feedback with a compact frame, the motor supports precise interpolation, smooth velocity control, and repeatable positioning cycles demanded in modern industrial automation. The unit follows IEC mounting interfaces used for this motor class, allowing straightforward installation in compatible machine designs.

Thermal regulation is handled through natural convection, so heat leaves the housing without fans or external coolers, and adequate clearance around the surface is required. The motor carries a standard design housing that matches the mounting footprint used across the series. A rotatable 240° encoder connector eases cable routing in confined spaces. Feedback travels over the Hiperface digital interface, and the sensor delivers 128 signal periods per mechanical turn for fine commutation and accurate velocity loops. Rotary output is provided by a plain shaft, allowing couplings or pulleys to be press-fitted without keyways. The motor uses winding code 0300, with phase resistance, inductance, and rated current matched to the associated drive.

The scanning principle is optical, giving stable position values across temperature changes, while the feedback range is limited to one revolution by the single-turn configuration. Because the motor ships without a holding brake, vertical or load-holding axes must rely on external mechanical locks or drive torque when power is removed. The D-length stator pairs with the 070 frame size, balancing inertia against continuous torque for mid-range motion tasks. It is an IndraDyn S synchronous servomotor for use with compatible Rexroth drive systems.
