Product Description:
The MSK076C-0450-NN-M2-UG1-RNNK is a synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. This IndraDyn S unit converts drive-controller commands into accurately regulated torque and speed for positioning, contouring, and feed axes in automated packaging lines, machining centers, and material-handling gantries. A permanent-magnet rotor and compact stator provide high power density while preserving installation space inside multi-axis assemblies, making the motor suitable for precise servo applications that require responsive acceleration, stable speed control, and compact machine layouts.
Mechanical dimensions are set by motor size 076 and length code C, providing a mid-frame package that pairs with winding code 0450 for compatible electrical characteristics in this housing size. Cooling is handled through natural convection, eliminating fans and permitting fully passive operation when the housing is bolted to a machine plate. Rotor position is captured by an optical encoder that transmits data over EnDat2.1 with a resolution of 2048 signal periods per revolution, supporting high-bandwidth velocity loops and accurate position control. An electrically released holding brake supplies 11 Nm of static torque to secure vertical loads during power-off states. The motor is sealed to IP65, protecting internal parts against dust and low-pressure water jets during routine washdown or coolant splash.
Cable management benefits from a rotatable encoder connector that turns 240°, allowing the feedback plug to align with cabinet entries or drag-chain routing and reducing cable strain in confined layouts. Absolute position retention is ensured by a multi-turn absolute feedback method that records shaft revolutions even when power is removed. Continuous duty is permitted from 0 to 40 °C, while insulation class 155 protects the windings from thermal stress during intensive cycle rates. A plain shaft supports clamp hubs or backlash-free couplings for direct integration with gearboxes and other drivetrain components where accurate alignment and low backlash are important.
