Product Description:

The MSK071D-0300-NN-M2-UG0-RSNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a rotary actuator, the motor converts drive current into controlled mechanical output for indexing tables, gantry drives, and other precision motion tasks that demand high positional repeatability in automated production cells. It is commonly paired with a servo drive that regulates torque, speed, and position during synchronized machine operation.

The motor body corresponds to size 071, and the frame uses length code D, a geometry that balances installation depth with torque density. Winding code 0300 identifies the conductor arrangement and electrical resistance used for this variant. Cooling relies on natural convection, so heat leaves the housing through surface exposure without fans and requires open airflow around the motor. Feedback is provided by an optical encoder that produces 2048 signal periods per mechanical revolution, allowing the drive to interpolate position with high granularity. This helps the axis maintain accurate speed and position control during dynamic motion.

The feedback assembly uses EnDat2.1, which delivers digital position data and supports automatic parameter storage in the drive. Its circular connector is rotatable through 240°, allowing the cable exit to be oriented to suit the machine layout. The encoder operates in multiturn absolute mode, so it records revolutions beyond a single turn without battery support. Mechanical output is transferred through a plain shaft that mates with backlash-free couplings, and the motor is supplied without a holding brake, so vertical loads require external holding force. This version also has increased concentricity and explosion protection, which reduce vibration and allow use in areas where ignitable gases may be present.
