Product Description:
The MSK071C-0200-NN-M3-UG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It delivers controlled rotary motion for machine axes, conveyors, and tool drives used in industrial automation cells, where accurate speed and position response are required during repeated operating cycles. When paired with a compatible drive, it supports regulated torque delivery for indexing, feeding, and general positioning tasks. The unit uses a plain shaft for direct coupling and follows the standard mechanical design of this motor platform, which supports straightforward integration into compact motion systems.
Cooling is handled by natural convection, meaning heat leaves the housing through external surface area without forced airflow, which simplifies cabinet layouts. Because cooling does not rely on forced airflow, surrounding layouts do not need space for a separate fan assembly. Position feedback is exchanged over the Hiperface interface, enabling digital communication of angle, speed, and diagnostic data to the drive controller through two hybrid conductors. The encoder plug is rotatable 240°, so cables can be routed in multiple directions inside cramped enclosures and around adjacent machine components. Internal measurement accuracy stems from a resolution of 16 signal periods per mechanical revolution, and this spacing supports stable low-speed motion with responsive loop control. Signal generation is based on a capacitive sensing method that remains reliable under vibration and temperature shifts.
An electrically released holding brake supplies 23 Nm of static torque to secure vertical loads when power is removed. This helps the axis remain fixed during shutdowns or other periods when drive torque is unavailable. The feedback device is a multiturn absolute encoder, so the controller retains shaft position across 4,096 revolutions without a homing move after shutdown. The motor has size 071 and length C, which keeps the housing suited to medium-duty stations where installation space is limited. Electrical characteristics follow winding code 0200, matching the stator impedance and back-EMF to compatible IndraDrive amplifiers on common DC bus voltages.
