Product Description:

The MSK075E-0450-FN-M2-UG1-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into rotary motion for precise axis control in CNC machines, packaging lines, and other automated equipment where repeatable positioning and stable speed control are required. The 075 frame size with the E length variant places the motor in the medium-power range of the platform, giving a useful balance of torque density and compact dimensions for tightly packaged machine axes. This format suits systems that need a responsive servo motor without moving to a larger frame.

Thermal stability is maintained through liquid cooling, allowing higher continuous load without thermal derating. The motor has increased concentricity, which reduces shaft runout when a plain shaft is coupled directly to precision gear stages or other accurate drive elements. A rotatable 240° encoder connector helps simplify cable routing in tight enclosures. Position data are transferred through the EnDat 2.1 interface, and the optical sensor provides 2048 signal periods per revolution. Its multiturn absolute feedback preserves rotor position after power loss, so the axis can return to operation without a reference move. The selected winding code 0450 and insulation class 155 align the electrical design with standard IndraDrive inverters, and an electrically released holding brake is integrated.

The holding brake provides 23 Nm of static torque to secure vertical or suspended loads during shutdown. A housing rated at IP65 blocks dust ingress and low-pressure water jets, allowing installation outside sealed cabinets when the surrounding machine layout permits it. Reliable operation is supported across an ambient range of 0 to 40 °C, so the motor can maintain its intended performance in typical industrial spaces. The sealed housing also helps protect internal components from contamination during routine machine operation.
