Product Description:

The MSK076C-0450-NN-S2-UP1-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is used in industrial automation to drive axes that require accurate position and velocity control under servo feedback, including indexing and synchronized motion tasks. The encoder connector can be rotated 240°, which helps with cable routing in tight machines. The motor uses size 076 with length C, and its rotor design is intended for increased concentricity to reduce runout during high-speed cycles.

Heat is removed by natural convection, so no external blower or liquid loop is needed during normal operation. The housing has a protection rating of IP65, allowing operation in dusty environments and during washdown with low-pressure water jets. A holding brake rated at 11 Nm is integrated and releases electrically, providing secure load retention when power is removed. Position data come from an optical encoder that provides 2048 signal periods per revolution and communicates through the EnDat2.1 digital interface, giving the drive controller high-resolution feedback for interpolation and stable closed-loop motion.

The encoder uses an optical scanning principle and a single-turn topology to provide precise absolute position within one revolution, which suits many indexing and tool-changing tasks while reducing memory demand in the drive. Continuous operation is intended within an ambient range of 0 to 40 °C, and this window aligns with insulation class 155 so thermal margins remain intact without forced cooling. Winding code 0450 identifies the electrical winding used with standard IndraDrive power modules, supporting predictable current response. Output torque is transferred through a shaft with a keyway, giving straightforward coupling to gears, pulleys, or rigid flanges without relying on friction-lock hubs.
