Product Description:

The MSK076C-0450-NN-M2-UG0-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. This motor serves as a compact rotary actuator that couples to an IndraDrive controller and delivers closed-loop position and velocity control in automated packaging machines, gantry axes, and material-handling stations. Its mechanical design emphasizes low cogging torque and increased concentricity so that repetitive motion profiles remain consistent even under varying load conditions. That operating profile makes it well suited for axes that need smooth indexing, accurate speed changes, and repeatable motion over frequent start-stop cycles.

Passive cooling by natural convection dissipates the heat generated by copper losses, allowing the motor to work continuously without external fans or liquid circuits. Feedback is handled through an optical encoder that communicates via the EnDat2.1 interface, and this digital link supplies absolute position data to the drive. The encoder offers 2048 signal periods per revolution, giving the controller fine angular resolution for smooth speed regulation and precise command tracking. The motor is supplied without a holding brake, so any static load retention must come from the drive or external mechanisms. A housing rated at IP65 shields the stator, bearings, and connector hardware from dust ingress and low-pressure water jets in typical factory environments.

The optical transducer records turns in a multiturn absolute format, allowing the axis to report its position across power cycles without a separate homing routine. Operation is permitted from 0 to 40 °C, which suits standard indoor production areas and enclosed machine spaces. A plain shaft eases coupling to precision gearheads or timing pulleys by eliminating keyway stress concentrations and supporting clamp-style hubs. Class 155 insulation helps the winding tolerate elevated thermal stress during sustained operation. The motor uses the M2 winding in frame size 076 with length C geometry, and its rotatable 240° connector supports flexible cable routing while the increased concentricity design helps limit radial runout in high-speed applications.
