Product Description:
The MSK071D-0450-NN-M3-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. The unit forms the electromechanical link between a servo drive and the driven machine element, providing precise rotary motion for indexing tables, gantry axes, or spindle heads. Its electrical winding, magnetic stack, and integrated feedback system make it suitable for tightly regulated industrial automation tasks that demand repeatable positioning under variable loads. In closed-loop motion systems, the integrated feedback allows the paired drive to monitor rotor position continuously and correct deviations caused by changing inertia or process load.
Thermal management relies on natural convection, so the housing dissipates heat without forced airflow and does not require an auxiliary fan. A protection rating of IP65 helps seal the stator against dust ingress and water jets, supporting direct installation on moving machine sections. Connection of the feedback device is simplified by a 240° rotatable encoder connector that can be oriented to clear adjacent hardware and maintain suitable cable routing. Position data is transmitted over the Hiperface interface, and the internal sensor provides 16 signal periods per mechanical revolution for commutation and feedback processing. This connector arrangement is useful where cable exit direction is limited by guards, frames, or neighboring axes.
Within the motor, the capacitive scanning principle tracks a multi-turn absolute code, preserving position information after power loss without external batteries. The shaft interface uses a plain shaft, so couplings can be mounted without a keyway. Continuous operation is permitted at ambient temperatures of 0–40 °C, which fits typical industrial environments. Winding code 0450, length class D, and size 071 set the motor’s electromagnetic layout. The standard construction uses insulation class 155, and the servomotor is supplied without a holding brake, so vertical or suspended loads need a separate mechanical restraint when power is removed.
