Product Description:
The MSK101D-0450-NN-S2-BP2-RNNN servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Built as an IndraDyn S synchronous servomotor, it converts controlled AC drive power into precise rotary motion for industrial positioning and feed tasks. The frame size 101 housing and D-length stator section accommodate a larger magnetic stack, and the increased concentricity design helps minimize radial runout during repeated axis movement. This layout suits applications that need stable motion, accurate path tracking, and repeatable response during frequent acceleration and deceleration. When paired with a compatible drive, the motor supports closed-loop operation for demanding automation axes.
Under rated load, heat is dissipated by natural convection, although heavy-duty applications may require forced airflow. Feedback is supplied through a single-turn optical encoder with the EnDat2.1 interface and 2048 signal periods per revolution for precise position monitoring. The electrically released holding brake provides 70 Nm of static torque for power-off holding on vertical or index axes. The motor has an IP65 protection rating, and the B-side power connector keeps motor cabling clear of adjacent mechanical components. The optical feedback channel also helps the drive respond quickly to command changes and load variations during normal operation.
The output is a shaft with keyway, which helps prevent slip during reversing operation. Continuous duty is permitted in an ambient range of 0 to 40 °C. Insulation class 155 supports elevated winding temperatures, and winding code 0450 identifies the electrical characteristics required for matching drive control. Optical scanning of the encoder disc eliminates mechanical wear and helps preserve fine resolution over the motor’s service life. A keyed shaft also supports secure connection to common couplings and transmission elements used in automated machinery.
