Product Description:

The MSK040C-0450-NN-S1-UG1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a torque-generating element in closed-loop industrial axes, it converts drive current into controlled rotary motion for pick-and-place stations, packaging equipment, and similar machinery. It is intended for applications that require accurate positioning and stable speed control during repeated motion cycles.

This model relies on Natural convection, so enclosure fins dissipate heat without external fans or liquid circuits. Position data are issued through a rotatable 240° encoder connector that mates directly with drive cabling. Inside the housing, an encoder built on the Hiperface interface measures shaft angle with 128 signal periods per mechanical turn, and the Optical scanning method provides high incremental accuracy without magnetic drift. Because the measurement system is Singleturn, absolute position is retained for one revolution, which suits short-stroke motion. Length code C extends the active lamination stack so continuous torque capacity is higher than in shorter variants without increasing the frame width.

An electrically released holding brake is mounted at the non-drive end to secure vertical loads, and it applies 4 Nm of static torque when power is removed. Power is routed through a Plain shaft, which simplifies coupling to low-inertia hubs. Winding code 0450 identifies the copper cross-section and turns per phase so the motor matches MSK family drives with the required voltage constants. Frame size 040 keeps the flange dimensions compact, allowing installation in tight multi-axis clusters while maintaining compatibility with IEC mounting patterns. This layout supports secure standstill behavior and consistent integration into closed-loop servo systems.
