Product Description:
The MSK071D-0450-NN-M2-UP0-RNNN servomotor is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an integrated drive element, it converts drive-controller output into precise rotary motion for automated machine axes, tooling spindles, and material-handling stations in industrial automation. Its compact construction and coordinated encoder system support closed-loop positioning with high repeatability. Because feedback is integrated into the motor, the paired drive can monitor rotor position continuously and correct for load changes during acceleration and deceleration. That behavior suits packaging, indexing, and transfer tasks that depend on repeatable starts and stops rather than simple fixed-speed running.
The motor body uses size 071 geometry with D length and winding code 0450, giving a torque-speed profile suited to medium-inertia loads. Heat is removed by natural convection, so the installation must preserve free airflow around the housing. The stator and rotor are machined for increased concentricity to help minimize radial runout during rotation. The housing is rated IP65, which helps keep dust and water jets away from internal parts. For flexible cable routing, the encoder connector is rotatable through 240°, and signal transmission uses the EnDat2.1 serial interface. Position feedback is provided at 2048 signal periods per revolution for fine interpolation in speed and position control.
The feedback system uses optical scanning and multiturn absolute feedback, so the motor can report shaft position after power loss without a homing cycle. Continuous service is supported in an ambient range of 0 to 40 °C, and the insulation system is Class 155 for higher winding temperature tolerance before derating is required. The output is a shaft with a keyway, which supports conventional couplings and helps prevent slip under load. This arrangement also allows straightforward connection to pulleys, gearboxes, and other driven components that use keyed hubs. The motor is supplied without a holding brake, so any required static load retention must be provided by external braking or clamping hardware.
