Product Description:

The MSK071C-0450-NN-S1-UG1-NNNN is a synchronous servo motor designed by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an electrically commutated AC motor, it supplies closed-loop torque and position control to packaging lines, pick-and-place gantries, and other automated axes. The unit has a size 071 frame and a 0450 winding, allowing pairing with compatible IndraDrive controllers in modular motion systems. Its synchronous design supports accurate starts, stops, and repeatable positioning during fast machine cycles. It is intended for dynamic motion tasks where repeatability is more important than simple constant-speed operation.

Heat is removed through natural convection, so installation must allow unobstructed airflow around the housing, and no fan or liquid circuit is required. A factory-mounted, electrically released holding brake applies 23 Nm to secure vertical loads when power is removed. The motor sends feedback through a Hiperface optical encoder with 128 signal periods, and this resolution supports precise commutation and position tracking. Because the scanning principle is optical, the feedback signal is not influenced by magnetic stray fields. This feedback arrangement also gives the drive a stable reference during rapid speed changes. The single-turn design tracks one mechanical revolution, and the rotatable connector allows cable exit alignment without twisting the conductors.

The feedback plug can rotate through 240°, which helps route cables in crowded cabinets or around adjacent machine members. Power is transmitted by a plain shaft, allowing direct coupling to gearheads or pulleys where a keyed interface is not required. The compact 071 frame with length code C keeps inertia moderate while still accommodating the 0450 winding, which corresponds to the motor's voltage constant and current demand. The brake and encoder are integrated into the motor package, which reduces the number of separate external components around the axis. This layout suits indexing, feeding, and transfer axes that require accurate motion in limited installation space. Compact cable routing and self-cooling help when several axes are mounted close together inside packaging or printing machinery.
