Product Description:

The MSK043C-0600-NN-S1-AG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical power into controlled rotary motion for positioning axes and feed drives in industrial automation. A C-length frame and 043 size stator give the motor a compact profile suited to tight machinery layouts, and the plain shaft simplifies coupling with gearboxes or direct-drive mechanisms while helping maintain low torsional backlash. This arrangement makes the unit suitable for compact axis assemblies where installation space is limited but accurate motion control is still required.

Heat dissipation relies on natural convection, meaning the housing transfers thermal energy to the surrounding air without fans or external coolers. Position feedback is supplied through the Hiperface interface, allowing digital communication between the motor encoder and compatible Rexroth drive controllers. The optical encoder produces 128 signal periods per revolution, and the drive can interpolate that signal for finer motion control. Because the scanning principle is optical, the feedback system uses a light-based reading method, and the single-turn design provides absolute position information within one mechanical revolution. This supports stable startup behavior and reliable position tracking on short-stroke and indexing applications.

The rotor is supplied without a holding brake, so any load that must remain fixed during power-off requires an external holding device. The housing has an IP65 rating, which helps protect internal components from dust and water jets commonly found on production floors. Continuous service is permitted at ambient temperatures of 0–40 °C, and the windings use insulation class 155 for thermal durability. An A-side power connector, winding code 0600, and a standard housing design create a straightforward motor package for compact machine layouts. These features make the motor easy to integrate where sealed construction, direct feedback, and fanless cooling are preferred.
