Product Description:

The MSK040C-0450-NN-S1-UG0-NSNN servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is a permanent-magnet drive element intended for highly dynamic positioning and speed loops in automated assembly cells, packaging lines, and material-handling gantries. By combining a compact 040 frame with a C-length stator, the unit provides high torque density where installation space is limited and short cycle times are required. Integration with IndraDrive controllers supports sinusoidal current regulation and fully digital feedback, helping the motor deliver smooth motion and accurate axis response. This arrangement suits servo axes that require frequent reversing, precise indexing, and stable speed control under changing loads.

It relies on passive cooling through natural convection, so no external fan or liquid circuit is necessary and heat is dissipated through the housing. A molded radial seal and cable glands provide an IP65 rating, which helps protect the motor when it is mounted near airborne dust or fluid splash. Position data are transmitted through the Hiperface interface, and the integrated encoder provides 128 signal periods per mechanical revolution for interpolation inside the drive. Because the feedback uses an optical scanning principle, it maintains accurate position information without the magnetic drift associated with some other sensing methods. The encoder data allows the connected drive to monitor rotor movement closely during both speed changes and fine positioning tasks.

The feedback unit delivers absolute information in a single-turn format, so the drive can identify shaft position within one revolution after power-up. Electrical insulation conforms to class 155, allowing the winding system to operate within an ambient range of 0 to 40 °C. Winding code 0450 indicates the electrical characteristics used with compact IndraDrive amplifiers. A rotatable 240° connector allows the feedback cable to exit in a suitable direction for the machine layout, and the plain shaft supports direct coupling to gearheads or timing-belt pulleys. The motor is supplied without a holding brake, so any required holding force at standstill must be provided by the drive or by an external mechanical device.
