The MSK075E-0450-FN-M2-UG2-RNNN servomotor by Bosch Rexroth Indramat is a robust member of the MSK IndraDyn S Synchronous Motors series. Featuring liquid cooling and an electrically released holding brake, this motor delivers reliable performance in high-demand automation tasks. With a motor size of 075 and a motor length of E, it is engineered to provide precise motion control in compact machine builds. Its primary function is to offer high-dynamic positioning and torque stabilization for CNC machines, robotics, and other precision-driven industrial applications.



Designed as an IndraDyn S Synchronous Servomotor, the MSK075E-0450-FN-M2-UG2-RNNN stands out with a continuous torque at standstill (100 K) of 23.0 Nm and a corresponding continuous current of 15.6 A, ensuring steady holding force during standstill. Under peak demand, it delivers a maximum torque of 88.0 Nm with a maximum current draw of 63.9 A, enabling rapid acceleration and high-load handling. The winding inductivity of 4,460 mH contributes to smooth current transitions and reduced torque ripple. Its 0450 rated speed code allows reliable operation at medium to high speeds without compromising thermal limits.



This motor requires the FN liquid cooling constraint for optimal heat dissipation and benefits from a design with increased concentricity, enhancing durability and shaft stability. The plain shaft interface simplifies coupling with machine components, while the integrated multiturn absolute encoder with optical technology and EnDat2.1 interface provides 2048 signal periods resolution and a rotatable, 240° encoder connector for flexible installation. Equipped with a 30 Nm holding brake, it secures loads during power loss or maintenance. In industrial environments, this servomotor’s efficient cooling, precise feedback, and robust brake system maximize uptime and accuracy, making it ideal for high-precision automation and demanding production settings.
