The Bosch Rexroth Indramat MSK075E-0300-NN-S2-UP0-RNNN from the MSK IndraDyn S Synchronous Motors series features the IndraDyn S Synchronous Servomotor product type. This motor size 075 unit with a motor length E and rated speed code 0300 delivers a compact footprint with an increased concentricity design. Constructed without a holding brake, the shaft with keyway ensures reliable torque transmission. Cooling is achieved via natural convection for silent, maintenance-free operation. Engineered for integration with Rexroth drives, this servo motor offers plug-and-play commissioning.
The electrical architecture supports a continuous current at standstill of 15.6 A (100 K) and generates a continuous torque at standstill of 23.0 Nm (100 K), scaling to a maximum current of 63.9 A and a maximum torque of 88.0 Nm. A high winding inductivity of 4,460 mH smooths current ripple and enhances dynamic response. Encoder automation is enabled by an optical singleturn design with 2048 signal periods resolution, interfacing via EnDat2.1 over a rotatable, 240° encoder connector. The high inductivity and singleturn encoder ensure minimal overshoot and fast settling times, delivering precise motion control in dynamic applications.
Mechanical integration is streamlined by the standardized foot and flange dimensions of the MSK series and the robust concentric bearing arrangement. The combination of high torque density, passive cooling, and high-resolution encoder feedback makes the MSK075E-0300-NN-S2-UP0-RNNN ideal for demanding positioning and servo applications in packaging, machine tools, and robotics. With its robust design and low maintenance requirements, this motor reduces lifecycle costs and downtime.
