Product Description:
The MSK070D-0300-NN-M2-UP0-RNNN is a servomotor produced by Bosch Rexroth Indramat and supplied as a member of the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and speed tasks in industrial automation lines. The compact synchronous motor can couple directly to precision gearboxes, actuators, or rotary tables.
Cooling is through natural convection, so no external fan or liquid circuit is required. This simplifies cabinet layout and limits maintenance points. The motor is supplied in length code D and uses winding code 0300. For position feedback, the unit uses an encoder with a rotatable 240° connector that simplifies cable routing inside tight enclosures. Electrical communication is provided over the EnDat2.1 interface, allowing single-cable transmission of position, temperature, and diagnostic data. Because the measuring principle is optical, magnetic stray fields from adjacent components do not degrade accuracy, and it delivers 2048 signal periods that the drive interpolates for finer resolution. A shaft with a keyway permits positive-fit torque transfer to pulleys or couplings. The motor is supplied without a holding brake, so external braking or drive torque must secure standstill loads.
The shaft and bearing seats are machined for increased concentricity, which keeps runout low and minimizes torque ripple during indexing routines. The absolute encoder maintains position information over multiple revolutions, and its operating mode is multiturn absolute, so homing cycles are unnecessary after power loss. Size code 070 balances compact external dimensions with enough stator volume to dissipate heat produced during continuous duty under convection cooling. These attributes support high-duty pick-and-place axes, light packaging spindles, and other applications that require consistent accuracy.
