Product Description:

The MSK071E-0200-FN-S1-UG2-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for precise position and speed control in automated machinery. It belongs to the MSK IndraDyn S Synchronous Motors series and uses the standard design variant. The frame uses motor size 071 with the elongated E length, which provides additional active iron for higher continuous torque. The FN suffix indicates that the motor uses an external cooling circuit so it can maintain rated output in continuous-duty applications. This layout suits medium-power axes that need steady output from a comparatively compact mounting envelope.

The motor relies on liquid cooling through the stator jacket to remove losses generated by winding code 0200 and to keep the insulation system within the Class 155 temperature limit during continuous operation. A protection rating of IP65 seals the housing against dust ingress and low-pressure water jets, allowing direct machine mounting without a separate enclosure. The electrically released holding brake provides 30 Nm of static torque so vertical loads can remain secure when supply power is removed. Position feedback is delivered by an encoder that produces 128 signal periods per revolution, and its connector can rotate 240° to simplify cable routing in tight motor bays and crowded machine frames.

The feedback element uses optical scanning and the Hiperface serial interface, providing single-turn absolute position data for precise commutation and position tracking. The motor has a plain shaft that couples directly to clamp or friction hubs and avoids the stress concentration associated with keyed connections in clean, direct-coupled applications. The assembly operates across an ambient range of 0–40 °C, which matches the temperature conditions commonly found in packaging lines, machine tools, and other enclosed automation equipment.
