Product Description:
Bosch Rexroth Indramat manufactures the MSK071E-0200-NN-S2-UP1-RNNN IndraDyn S synchronous servomotor, a member of the MSK IndraDyn S Synchronous Motors series. The E-length rotor and permanent magnets deliver high torque density for positioning tables, pick-and-place gantries, and articulated robot joints. Within an automation cell, the unit converts drive current into controlled rotary motion that can be coordinated by IndraDrive controllers through its digital feedback interface. Along with torque generation, it supplies absolute position data to the drive, enabling tight motion loops and repeatable axis control.
Heat generated in the stator is removed through natural convection, meaning the housing fins alone maintain the winding temperature during continuous duty. The enclosure has an IP65 ingress rating, so internal components remain sealed against dust and low-pressure water jets commonly found in industrial settings. An encoder inside the motor produces 2048 signal periods per revolution; after interpolation by the drive, this high resolution supports precise position loops. For mechanical holding, the spring-applied brake can oppose up to 23 Nm of static load when power is off. The motor uses the MSK frame code 071, which provides a shaft center height and flange pattern compatible with medium-power drives in the IndraDrive ecosystem. The keyed shaft simplifies torque transmission to couplings or pulleys without slip.
The feedback lead exits through a rotatable connector fixed at 240°, allowing the cable to clear adjacent drives or bulkheads without twisting. Position data and electronic nameplate information travel over EnDat2.1, removing the need for separate incremental channels. Continuous service is specified for ambient temperatures of 0–40 °C, and windings insulated to class 155 tolerate elevated internal temperatures before derating occurs. The single-turn optical encoder, keyway shaft, E-length rotor, winding code 0200, and increased concentricity design support stable, low-vibration operation during rapid acceleration.
