Product Description:

The MSK071E-0450-NN-M3-UG0-NNNN is a synchronous servo motor from the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It transforms controlled current from a drive controller into precise rotary motion for positioning tables, gantry axes, and other automated equipment that require tight velocity and torque regulation. The integrated feedback system supports closed-loop operation without a separate external position sensor on the axis. This arrangement helps maintain repeatable starts, stops, and speed changes in modular machine frames.

Thermal dissipation is handled by natural convection, so the aluminum housing must remain exposed to ambient airflow to keep winding temperatures within operating limits. Position feedback travels over the Hiperface interface, combining incremental and absolute data on a single serial link for simpler cabling. Inside the motor, the encoder resolves rotation into 16 signal periods per electrical cycle, supplying fine-grained interpolation to the drive. Its sensing element is capacitive, which tolerates electromagnetic fields that can disturb optical systems. The feedback device is a multi-turn absolute type, so stored position information remains available after power is removed. A 240° rotatable connector eases lead-out alignment in cramped cabinets, and winding code 0450 matches the electrical constants expected by the connected drive.

The housing complies with IP65, blocking dust ingress and protecting live parts against low-pressure water streams common in machining cells. Torque is delivered through a plain shaft, allowing clamp or shrink couplings without keyways. Ambient operation must remain between 0 to 40 °C, and within this window the insulation system, rated for class 155, endures continuous thermal stress without premature aging. Because the unit is supplied without a holding brake, the axis must rely on external locking hardware or static drive torque to maintain position when power is off.
