Product Description:

Bosch Rexroth Indramat manufactures the MSK071C-0300-NN-M1-UP0-NNNN. This servo motor belongs to the MSK IndraDyn S Synchronous Motors series and provides closed-loop torque and position control in assembly cells, packaging stations, and other automated axes. When paired with an IndraDrive controller, it converts digitally generated setpoints into accurate rotary motion for synchronized indexing, feed movements, and positioning tasks. The motor is suited for applications that require repeatable response during frequent starts, stops, and direction changes.

The unit relies on natural convection to transfer heat from the stator to ambient air, so no external blower or liquid circuit is required. With a frame size of motor size 071, its mounting footprint and flange pattern suit compact mid-range machinery. Winding code 0300 gives the electrical characteristics expected by standard MSK power modules. A field-installable connector with rotatable, 240° positioning reduces cable stress by allowing the encoder plug to exit in the preferred direction after installation. Feedback is exchanged over the Hiperface serial interface, so absolute position data and electronic motor data travel on the same two-wire pair. This layout helps keep wiring straightforward in machines where space around the motor is limited.

The optical feedback device resolves the rotor angle into 128 signal periods, and interpolation inside the drive raises this base resolution for smooth commutation and accurate positioning. Because the sensing method is optical, magnetic stray fields from nearby motors or brakes do not affect the scale reading. The encoder is a multiturn absolute model, so the controller receives valid position values across 4,096 revolutions without a reference run after power-up. Mechanical energy is transferred through a keyed shaft, which supports secure coupling to driven components such as pulleys or gear inputs. The motor is supplied without a holding brake, so any static load must be secured by the machine design or by controlled drive torque when the axis is stopped.
