Product Description:

The MSK071E-0200-NN-M1-UP2-NSNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat. It belongs to the MSK IndraDyn S Synchronous Motors series and is used on closed-loop motion axes in industrial automation equipment. The type code indicates motor size 071, length E, and winding code 0200. This servomotor is intended for precise positioning and speed control, where the drive continuously corrects torque output in response to load changes. Its construction supports both standard and explosion-protected installations, and the motor is intended for systems that provide the required FN cooling category.

Heat is dissipated by natural convection, so installation clearances must let air pass freely around the housing. Position feedback is delivered through an optical encoder that uses the Hiperface protocol, giving digital data to the drive controller. The encoder provides 128 signal periods, and its multi-turn absolute format reports shaft position across multiple revolutions without battery backup. A rotatable 240° connector helps route cables cleanly in compact machine spaces. For power-off holding, the electrically released brake supplies 30 Nm of torque. This arrangement is useful on vertical axes or other applications where the load must remain in place when drive power is removed.

Environmental sealing to IP65 blocks dust and low-pressure water jets, making the motor suitable for machine areas exposed to washdown or airborne debris. The specified ambient range of 0–40 °C aligns with common industrial enclosures and supports normal operation within that window. Mechanical coupling is through a shaft with keyway, which provides positive torque transfer to pulleys, couplings, or gears. Internal insulation materials comply with class 155, allowing the winding system to tolerate elevated operating temperatures. This level of sealing also helps protect internal bearings and feedback components from contamination during routine machine cleaning. A keyed shaft also helps preserve angular orientation when pulleys or timing elements must stay aligned during repeated reversals.
