Product Description:
The MSK076C-0300-NN-S1-UG1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is used as a drive element in automation cells where precise rotary positioning and rapid speed changes are required, such as pick-and-place modules or indexing conveyors. Integrated optical feedback and an electrically released brake allow the motor to maintain position during machine idle while still supporting high-resolution closed-loop control when motion is commanded, including during restart after a stopped condition.
This model removes internally generated heat through natural convection, so installation must allow unobstructed airflow across the housing surfaces instead of adding a fan or liquid circuit. Feedback signals leave the motor through the Hiperface digital interface, giving the controller both absolute position data and electronic motor data over a single eight-wire line. Inside the encoder, the scale generates 128 signal periods per mechanical revolution; when interpolated by the drive, this fine count increases positioning accuracy and reduces velocity ripple during low-speed motion. The electrically released brake supplies a static holding capacity of 11 Nm, providing load security on vertical or suspended axes whenever power is removed from the stator windings and without relying on drive torque alone.
The single-turn measuring principle limits absolute feedback to one revolution, but it simplifies homing routines and reduces data traffic. Mechanical coupling relies on a plain shaft that inserts directly into keyed or clamped hubs for direct transmission of rotary motion to the driven mechanism. Frame size 076 identifies the stator diameter, while length code C indicates the active stack height chosen for moderate continuous torque in a compact footprint. Electrical performance aligns with winding code 0300, enabling the connected IndraDrive inverter to supply current and voltage that match the magnetic circuit impedance.
