Product Description:
The MSK040C-0450-NN-S1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In multi-axis packaging machines, pick-and-place gantries, and other precision assemblies, this motor converts drive current into regulated rotary motion. The associated controller can profile that motion for position, velocity, and torque loops in industrial automation. It is intended for coordinated servo applications in which the drive must respond quickly to commanded motion changes and load variation.
The motor relies on natural convection to move heat from the stator laminations to the ambient air, eliminating the need for external fans or liquid lines in many installations. A field-wiring-friendly encoder plug can be rotated through 240°, so the feedback cable can exit in the preferred direction without excessive bending. Because the connector can be repositioned, cable routing remains easier in compact machine frames with limited clearance around the motor. Digital position data are exchanged over the Hiperface interface, allowing transmission of absolute position values and stored motor data to compatible drive controllers. Inside the feedback unit, an interpolated scan of 128 signal periods supplies fine angular resolution for smooth servo loops, and the optical scanning principle helps avoid magnetic offset errors that can occur in Hall-based systems.
A single-turn measuring range is adequate for short-stroke axes where motion does not exceed one mechanical revolution, which keeps encoder complexity low. The output end carries a plain shaft that mates with zero-backlash couplings or pulley hubs without a keyway. This layout supports compact axis designs where low inertia and direct coupling are preferred over keyed shaft connections. The motor has size 040 and length code C, providing a balance between inertia and continuous torque for light to medium loads. The motor uses winding code 0450, which corresponds to the voltage constant and nominal current expected by the drive. Because the unit is supplied without a holding brake, vertical axes require an external clamp or a torque-holding drive mode during power-off conditions.
