Product Description:
The MSK071D-0300-FN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. It is intended for precision motion tasks where closed-loop position and velocity control are required, such as pick-and-place modules, tool axes, and packaging machinery. By pairing with Rexroth drive controllers, the motor converts commanded current into exact rotary motion while its integrated feedback device allows the controller to monitor rotor position in real time.
The stator is equipped with liquid cooling, so waste heat is removed through a coolant circuit rather than ambient air, allowing higher continuous torque in confined cabinets. An ingress protection rating of IP65 seals the housing against dust and low-pressure water jets, enabling direct installation on the machine frame. The motor can operate in ambient temperatures from 0–40 °C without derating, which aligns with typical plant conditions. The windings use insulation class 155, which tolerates winding temperatures up to 155 °C before thermal aging accelerates. A plain shaft transmits torque without keys, reducing runout and easing coupling with backlash-free clamping hubs. The model is supplied without a holding brake, so external clamping or drive torque must secure the load during power-off states.
Rotor geometry uses an increased concentricity design so radial runout stays low across the motor size 071 and motor length D envelope, while winding code 0300 matches the electrical characteristics expected by IndraDrive amplifier settings. Position feedback is provided through an EnDat2.1 optical encoder that delivers 2048 signal periods per revolution; this resolution supports fine interpolation within the drive for smooth speed loops. The encoder is a single-turn type, reporting absolute position over one mechanical turn, and its connector is rotatable through 240°, allowing cable routing to avoid tight bends inside machine enclosures.
