Product Description:

The MSK076C-0300-NN-M2-CG1-RNNK is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Intended for precise motion control in automated machinery, the unit converts drive currents into repeatable torque and position profiles while maintaining compact dimensions. It acts as the mechanical output stage for IndraDrive power modules, allowing tight closed-loop regulation of conveyor axes, tool heads, or packaging pick-and-place stations. Designed for cabinet or open-machine mounting, the motor’s low rotor inertia supports rapid acceleration and smooth reversal during high-cycle tasks.

Thermal management is handled through natural convection, so the housing dissipates its losses without fans or liquid circuits, reducing maintenance and ambient noise. Position feedback comes from an encoder that communicates via EnDat2.1 and delivers 2048 signal periods per mechanical turn; the optical scanning principle limits drift and ensures clean incremental and absolute signals for the controller. The motor follows size 076 and length code C, and winding code 0300 matches the electrical constants expected by standard IndraDrive amplifiers. A plain shaft transmits torque directly to the load, and an electrically released holding brake secures the axis when supply power is removed.

The encoder also stores total revolutions; this multiturn absolute feature eliminates homing cycles after an emergency stop or maintenance event. The brake produces 11 Nm of static torque, permitting secure load holding on vertical or rotary positioning stages. The motor has IP65 protection, providing full dust protection and resistance to low-pressure water jets when the shaft seal is fitted. All operating points are specified for ambient conditions from 0 to 40 °C, and the stator uses insulation class 155, allowing continuous winding temperatures up to 155 °C without thermal degradation of the varnish or winding wire.
