Product Description:

The Bosch Rexroth Indramat MSK040C-0600-NN-M2-UG1-NNNK is a servo motor in the MSK IndraDyn S Synchronous Motors series. Intended for precision automation, it transforms regulated three-phase drive power into controlled torque and velocity for gantry axes, indexing tables, robotic joints, and other synchronized motion systems. As a synchronous servo motor, it is intended for closed-loop applications where the drive regulates position, speed, and torque with high repeatability. The 040 frame size with C length keeps the overall package short, supporting installation where high-performance motion components must fit into limited space.

Heat produced by the windings is removed by natural convection, so no external cooling hardware is required. Rotor position is monitored by an optical encoder with a connector that is rotatable through 240°, allowing the cable to exit in a convenient direction. Positional data travel over EnDat 2.1, and the glass scale provides 2048 signal periods per mechanical turn for precise feedback. Because the measuring system is multi-turn absolute, it records up to 4096 revolutions without batteries after power cycles. That feedback lets the connected drive maintain accurate commutation and position control across low-speed and dynamic operating ranges. Optical sensing resists magnetic offset drift, and winding code 0600 corresponds to the current constants used during commutation.

An electrically released brake provides 4 Nm of static holding torque when the inverter is disabled. The die-cast housing meets IP65, helping keep dust and directional water jets away from the stator laminations and encoder compartment. A plain shaft allows direct clamping couplings without keyways, which helps keep torsional play low in high-precision assemblies. Rated operation spans 0 to 40 °C ambient, and insulation class 155 allows winding temperatures up to 155 °C during transient overloads. The brake helps hold the axis at standstill instead of serving as a dynamic stopping device. The sealing and shaft arrangement support use in machine sections exposed to dust, splash, or airborne contamination.
