Product Description:

The MSK076C-0300-NN-S1-UP1-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within automated machinery, it converts electrical power from an IndraDrive amplifier into precisely regulated torque and speed, allowing accurate positioning of pick-and-place heads, indexing tables, or conveyor axes across a full production cycle. It is intended for synchronized servo operation where quick response and consistent positioning are required throughout repeated machine cycles. The motor can be used on standalone rotary axes or on mechanically coupled drive trains that depend on steady closed-loop behavior.

Its cooling relies on natural convection, so thermal energy leaves the housing through surface fins without auxiliary blowers. Feedback accuracy is provided by an optical encoder that produces 128 signal periods per mechanical revolution. The feedback cable connects through a rotatable plug with 240° adjustment, giving a broad range for cable routing. Position and parameter data travel over the Hiperface protocol, while the single-turn scanning method supplies an absolute position within one motor turn, which helps avoid indexing errors during startup. The absolute interface also supports drive-based safety functions such as safe stop or safe limited speed. No battery is needed because the coded reference track stores its own position information.

The motor uses a C-length stator that balances thermal mass and installation depth within a standard mechanical design. An electrically released holding brake delivers 11 Nm of static torque, keeping vertical loads secure when power is removed. Output torque reaches the machine through a shaft with keyway, which eases direct coupling to pulleys or gearboxes. The motor has frame size 076 for its mounting pattern and flange geometry, and it uses winding code 0300 for the resistance and inductance expected by matched current loops. This brake and shaft arrangement suits axes that must remain in place at standstill while connecting to common keyed transmission components.
