Product Description:

The MSK071E-0300-FN-S2-UG2-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet AC unit, it delivers closed-loop torque and speed control to automated axes, material-handling stations, and packaging lines. The motor interfaces directly with Rexroth drive controllers to convert electrical command signals into precise mechanical rotation, providing the dynamic positioning required in modern industrial automation.

Thermal management is handled by liquid cooling, a feature that channels coolant through the stator jacket so continuous heat extraction is possible even under peak cyclic load. An electrically released holding brake delivers 30 Nm of static torque, allowing the axis to stay locked when power is removed. The housing carries an IP65 ingress rating, preventing dust and low-pressure water from reaching internal windings. Feedback is supplied through an EnDat2.1 optical encoder that generates 2048 signal periods per mechanical turn, enabling high-resolution drive control. The feedback plug is mounted on a rotatable connector set at 240°, which simplifies cable routing in tight cabinets.

The motor uses a single-turn scanning method, so absolute position data is retained within one revolution without additional battery support. Class 155 insulation permits winding temperatures up to 155 °C, while the specified ambient operating window of 0 to 40 °C maintains thermal headroom. A plain shaft transfers torque directly to couplings, and the increased concentricity design minimizes radial runout for smoother rotation. Size 071 and length code E indicate the frame geometry for machines with moderate footprint constraints, whereas winding code 0300 sets the electrical constants matched to standard MSK drives. The FN cooling requirement tag indicates that the built-in coolant circuit must be connected before operation.
