Product Description:

The MSK071E-0450-FN-M2-UP2-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. This 071-frame, E-length unit is intended for axes that require accurate position and speed control under changing loads. In packaging, handling, and forming equipment, it can couple directly to a gearbox or load shaft to provide closed-loop rotary motion. The integrated motor format helps keep the drive train compact while supporting repeatable movement in automated machinery.

For thermal management, the stator jacket uses liquid cooling, as indicated by the FN designation, so heat can be removed efficiently during continuous high-load operation. The housing is rated IP65, which helps protect internal components from dust and low-pressure water jets when the motor is mounted on the machine. An electrically released holding brake provides 30 Nm of static torque to hold a vertical or suspended axis when power is off. Position data is transmitted through the EnDat2.1 digital interface, and the integrated encoder delivers 2048 signal periods per revolution. This feedback arrangement gives the connected drive detailed position information for smooth speed regulation and accurate stopping.

The feedback device uses optical sensing with a multi-turn absolute track, so the drive can retain position information after shutdown without a homing cycle. Installation is easier because the encoder connector is rotatable through 240°, which allows more flexibility when routing cables in tight spaces. Winding code 0450 identifies the electrical characteristics matched to compatible Rexroth drive modules, and operation is specified for an ambient range of 0 to 40 °C. The motor also has increased concentricity to reduce runout in precision assemblies. Its keyed shaft provides positive torque transmission to the coupled mechanical load.
