Product Description:

Bosch Rexroth Indramat manufactures the MSK076C-0300-NN-M2-UP0-RNNN as part of the MSK IndraDyn S Synchronous Motors series. The motor serves as a direct-drive actuator for CNC tables, gantry axes, and material-handling equipment that require tight speed control and smooth low-speed torque. By integrating optical position feedback and a permanent-magnet stator package, the unit enables closed-loop motion tasks without external gear reduction, simplifying mechanical layouts and improving positioning accuracy. In modern automation cells, its balanced electromagnetic design minimizes cogging, supporting continuous interpolation routines.

Heat is removed solely through natural convection, so no forced airflow is required for cooling. Because it is delivered without a holding brake, any static load must be secured by the drive torque or an external clamp when power is off. The rotatable 240° encoder connector eases cable routing in crowded assemblies, and the optical feedback head communicates over the EnDat2.1 interface. With 2048 signal periods generated per mechanical revolution, the feedback system provides fine position information for closed-loop control. A keyed output shaft uses a shaft with keyway for positive coupling engagement.

Mechanical precision is enhanced by the increased concentricity design, keeping the magnetic centerline closely aligned with the housing axis and reducing radial runout during high-speed motion. The feedback device is a multiturn absolute encoder, so position across up to 4096 turns is retained after power cycling. Application sizing is supported by the compact 076 frame size and the medium C length, which are paired with winding code 0300. This arrangement keeps the motor compact while providing the electrical characteristics associated with that winding.
