Product Description:

The MSK071C-0300-FN-M2-UG2-RNNK is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a torque-dense servo unit, it converts drive current from a compatible inverter into precise mechanical motion for positioning, contouring, and speed control tasks in automated machinery. The motor ships with a plain shaft to couple directly to gearheads or load elements, and it is designated with the FN cooling requirement so it must be integrated into a machine circuit that supplies liquid coolant. This arrangement suits compact production equipment where accurate motion and stable thermal behavior are both required.

Thermal management is handled by liquid cooling, a closed-loop method that removes heat from the stator jackets and keeps winding temperatures stable during high duty cycles. The encoder subsystem communicates through the EnDat2.1 digital interface, allowing simultaneous transmission of position data and parameter memory to the drive controller. Within that encoder, the scale provides 2048 signal periods, so the controller can interpolate fine angular position for tight servo loops. An electrically released holding brake rated at 30 Nm supplies static torque to secure vertical axes or other loads when drive power is disabled. This helps hold position during stops without requiring an external mechanical clamp.

The feedback connector is rotatable through 240°, letting the cable exit be oriented away from nearby obstructions without twisting conductors. Position sensing uses a multiturn absolute structure with optical scanning, so absolute shaft angle is retained over multiple full rotations after power loss. Mechanical dimensions follow motor size 071 and length class C, providing a balanced mix of inertia and continuous torque for compact machine frames. The winding code 0300 matches the stator to the intended current and voltage range of compatible drive modules. These features support use on axes where space is limited, routing flexibility matters, and stored position data is needed after shutdown.
