The Bosch Rexroth Indramat MSK040C-0450-NN-S2-UP1-NNNN is part of the MSK IndraDyn S Synchronous Motors series and embodies the precision of a IndraDyn S Synchronous Servomotor with a compact Motor Size 040 frame and Motor Length C designation. This standard-design servomotor features a robust Shaft with keyway and is cooled by Natural convection to maintain optimal thermal performance without additional auxiliary systems. Its electrical architecture accommodates a Continuous Current at Standstill 100 K of 3.1 A and delivers a Continuous Torque at Standstill 100 K of 3.1 Nm, while supporting peak demands up to Maximum Current of 9.6 A and Maximum Torque of 8.1 Nm. The winding inductivity of 37,900 mH ensures smooth current flow and stable dynamic response across the speed range.
Advanced feedback control is provided by an integrated optical encoder with Singleturn capability and an Encoder Resolution of 2048 signal periods for precise position sensing. The encoder interface utilizes EnDat2.1 protocol over a Rotatable, 240° Encoder Connector, enabling flexible cable routing and simplified installation. An electrically released Holding Brake rated at 4 Nm secures the rotor in standstill conditions, making the unit ideal for vertical axis and safety-critical applications. The Rated Speed Code 0450 corresponds to a nominal speed optimized for servo loops requiring rapid acceleration and deceleration.
Designed for seamless integration into CNC machines, robotics, and high-precision automation, the MSK040C-0450-NN-S2-UP1-NNNN excels where compactness and torque density are paramount. Its standard footprint aligns with industry mounting conventions, and the keyway shaft ensures reliable torque transmission under cyclic loading. With natural convection cooling and high-resolution feedback, this servomotor streamlines both mechanical assembly and control-loop tuning in demanding industrial environments.
