Product Description:

The MSK070E-0300-NN-S2-UG0-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop servo axes in packaging lines, handling modules, and other automated machinery, where the motor converts commanded current into controlled torque and precise position feedback for the drive. The combination of size 070 and length code E gives the unit a compact housing that fits tightly spaced machine layouts while still supporting the dynamic response expected from a mid-frame IndraDyn motor. This format suits repeated indexing, synchronized conveying, and other applications that depend on accurate speed regulation and repeatable positioning. It also supports stable motion during frequent starts, stops, and direction changes.

Cooling is handled by natural convection, so the housing dissipates heat without a fan and surrounding airflow remains uncomplicated. The enclosure is rated IP65, which helps keep dust and low-pressure water jets away from internal components in washdown-prone areas. An optical encoder provides 2048 signal periods per mechanical revolution, and the EnDat2.1 interface transfers that position data to the drive for accurate real-time control. The rotor and stator use increased concentricity to reduce runout, while the plain shaft supports direct couplings and insulation class 155 permits winding temperatures up to 155 °C during cyclic load peaks.

The feedback connector is rotatable through 240°, which helps route cables in crowded enclosures without forcing a sharp exit angle. Feedback comes from a single-turn encoder, so the motor reports absolute position within one mechanical revolution and the control system handles multi-turn tracking separately. The permitted ambient operating range is 0 to 40 °C, allowing the motor to run beside other heat-generating components as long as the surrounding air stays within that band. Because the motor is supplied without a holding brake, any static load must be secured by the mechanical transmission or by controlled drive torque when the axis is at a standstill.
