Product Description:

The MSK071E-0200-FN-M2-UG2-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is designed as a high-precision rotary actuator for use on automated axes. The motor supplies controlled torque and speed to packaging, printing, and material-handling equipment, and it links directly to drive controllers in the overall motion system. Its synchronous design supports precise speed regulation and repeatable positioning during normal machine cycles.

This model uses liquid cooling, as indicated by the FN suffix, so thermal energy is removed by a closed coolant circuit rather than ambient air. Winding code 0200 identifies the stator conductors that pair electrically with Rexroth drive amplifiers, while frame size 071 and length E set the mounting envelope. Thermal Class 155 permits continuous winding temperatures up to 155 °C, and the machined design with increased concentricity reduces radial runout under load. Feedback reaches the controller through a rotatable 240° connector carrying the EnDat2.1 digital interface from an optical measuring system. Inside the encoder, 2048 signal periods per revolution are captured, and the multi-turn absolute format retains shaft position over multiple turns without battery support. The rotatable connector also helps route the feedback cable in tight machine layouts, and cooling through the liquid circuit reduces dependence on external airflow.

The housing meets the IP65 ingress standard, sealing internal components against dust and low-pressure water jets. A plain shaft eases direct coupling to gears or pulleys, and the electrically released brake holds up to 30 Nm to secure stationary loads during power-off states. The acceptable ambient range of 0–40 °C covers typical cabinet installations and supports continuous duty without derating. This combination of shaft and brake features suits axes that need straightforward coupling and secure holding at standstill.
