Product Description:

The MSK071E-0300-FN-S3-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. As a torque-dense, brushless unit, it is intended for positioning tables, pick-and-place gantries, and packaging axes that need rapid acceleration and repeatable accuracy. The motor integrates a liquid-cooled stator, a rotatable feedback connector, and high-resolution absolute sensing so that it can be coupled directly to the driven load without mechanical gear reduction, reducing backlash in closed-loop motion systems.

Heat generated in the windings is extracted through liquid cooling, allowing continuous torque output even at the current density set by winding code 0300. The 240° rotatable encoder connector lets the cable exit to the left, right, or rear, easing cable routing. Position data are transmitted over the Hiperface protocol, and the built-in measuring disk produces 16 signal periods per mechanical turn. Because the sensing element is capacitive, it withstands oil mist and conductive dust that can interfere with optical tracks. The feedback system is single-turn, so the absolute position is valid within one revolution and any multi-turn counting must be handled by the drive controller. These characteristics support tight position loops with minimal interpolation error.

The motor has an IP65 enclosure that resists dust ingress and low-pressure water jets. A plain shaft without a keyway lets users apply shrink-fit or clamp couplings matched to the load inertia. Operation is specified for ambient conditions of 0 to 40 °C, and the stator windings have insulation class 155, permitting high thermal headroom before degradation. Because the motor is supplied without a holding brake, stationary loads must be secured by external clamping or drive torque. Frame size 071 and length code E identify the motor's physical format within the MSK range.
