Product Description:

The MSK040B-0450-NN-S1-UG1-NNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. As an IndraDyn S synchronous servomotor, it provides closed-loop position and velocity control for packaging stations, handling gantries, and similar motion axes in industrial automation. Its standard design and compact frame support direct mounting on machine elements where accurate torque delivery and low maintenance are important. The motor is suited to applications that require fast response during repeated start-stop movement and precise speed regulation under changing loads. It can also serve pick-and-place mechanisms, feed axes, and transfer units that depend on repeatable motion profiles.

Thermal management relies on natural convection, so heat dissipates through the housing without forced air or liquid circuits. Cable routing is aided by a connection plug that is rotatable through 240°, allowing the lead to be positioned for the available installation space. Position feedback is transmitted over the Hiperface interface, and the optical encoder resolves shaft rotation into 128 signal periods. The feedback system uses optical scanning, which helps maintain stable signal quality and low interpolation error at high servo gains. This arrangement supports accurate commutation and position tracking across normal operating speeds.

Absolute position is reported as a single-turn value, which fits axes that return to a reference position after shutdown. For power-off holding, the electrically released brake provides 4 Nm of static torque to resist drift on vertical or indexing loads. Mechanical output is delivered through a plain shaft, which works well with clamp-type hubs and avoids the stress concentration of a keyway. The shaft arrangement is useful where couplings are mounted directly on the motor output. The motor uses size code 040 with length B, giving a compact envelope while accommodating winding code 0450 for its torque and speed class.
