Product Description:

The MSK050C-0450-NN-S1-UP1-NSNN is a servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed for industrial automation, it converts drive-controller current into rotational motion for feed axes, pick-and-place gantries, and other coordinated tasks where accurate speed and torque regulation are required. Its synchronous design supports repeatable acceleration and stable torque during frequent start-stop cycles in automated equipment. The motor uses frame size 050 with length code C, giving more continuous torque than the shorter A and B stacks while keeping the housing compact.

Heat generated by the stator is removed through natural convection, so no auxiliary fan or liquid circuit is necessary. The die-cast enclosure has an IP65 rating, which blocks dust entry and withstands low-pressure water jets during cleaning. Reliable service is maintained at ambient temperatures from 0 to 40 °C. Insulation class 155 allows the windings to operate at elevated temperatures without losing dielectric strength, and winding code 0450 matches the electrical characteristics used by the connected drive. Because cooling is passive, installation does not require fan maintenance or coolant plumbing around the motor body. A keyway machined into the solid shaft provides positive coupling for timing pulleys or gear wheels.

Axis homing and velocity loops are closed by an optical feedback system that uses a Hiperface interface. The encoder generates 128 signal periods per mechanical revolution and is factory-configured as a single-turn device, providing absolute position within one rotation. This feedback arrangement lets the drive detect rotor position immediately after startup and maintain accurate low-speed control. Its connector is rotatable through 240°, allowing cables to exit in several directions inside tight cabinets. For gravity-loaded axes, the electrically released holding brake supplies 6 Nm of static torque to lock the rotor during power-off or emergency stop events.
