Product Description:

The MSK040C-0450-NN-S3-UG0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In industrial automation it converts drive controller commands into precisely metered torque for positioning tables, pick-and-place heads, and light-duty spindle axes. Its compact 040 frame and C-length stator allow dense machine layouts where motion components must fit beside sensors, pneumatics, or safety hardware without increasing envelope size.

For heat removal the motor relies on natural convection, so no external fan or liquid circuit is required during continuous operation. Feedback is handled through the Hiperface protocol; inside the encoder a capacitive scanning element produces 16 signal periods per revolution, giving the drive fine-grained position data after interpolation. Because the feedback plug can be rotated through 240°, installers can direct the cable upward, sideways, or downward without stressing conductors in tight panels. The single-turn encoder design supplies absolute angle information for one mechanical turn, which is sufficient for short-stroke rotary axes. Mechanical power is transmitted through a plain shaft, simplifying the use of clamping couplings and minimizing torsional backlash. The winding code 0450 matches this rotor to medium-voltage IndraDrive amplifiers, while the standard design build omits an internal brake so external holding devices must secure vertical loads.

An enclosure rating of IP65 seals the housing against dust and low-pressure water jets, permitting installation on conveyors or robotic wrists that receive periodic washdowns. Continuous duty is specified for ambient temperatures between 0–40 °C, aligning with climate-controlled factory floors and most electrical cabinets. The Class 155 insulation system withstands winding temperatures up to 155 °C, allowing temporary overloads without degrading varnish or magnet wire.
