Product Description:

The MSK075C-0300-NN-M1-UP0-NNNN is an IndraDyn S synchronous servo motor from Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It converts drive-controller current into precise rotary motion for positioning tables, packaging axes, and other automated equipment that require tight velocity and torque control. A keyed shaft, standard mechanical design, and compact frame allow the motor to mount directly to couplings or belt pulleys in confined machine spaces. When used with a compatible servo drive, it supports controlled acceleration, stable running speed, and accurate stopping at commanded positions.

Heat removal is handled by natural convection, eliminating auxiliary blowers and simplifying the surrounding machine layout. The feedback plug is rotatable up to 240°, so cable routing can be adjusted to suit the available mounting space. Position data is exchanged through the Hiperface interface, letting the drive read absolute position and write motor parameters over the same four-wire link. Inside the encoder, optical sensing produces 128 signal periods per revolution, which the controller can interpolate for high-resolution velocity loops. This feedback arrangement supports responsive motion control on axes that must reverse direction frequently or hold a repeatable position.

The feedback module also uses multi-turn absolute position tracking, so the shaft position remains available after power cycles without requiring external homing sensors. An enclosure rating of IP65 helps keep dust and water jets away from internal components when the connectors are properly sealed. Torque is transferred through a shaft with a keyway, which provides positive mechanical engagement for pulleys, gears, and similar transmission elements. Continuous duty is permitted in ambient temperatures from 0 to 40 °C, and the motor is supplied without a holding brake, which suits applications where the machine mechanics or drive control provide static retention. Frame size 075 and the C-length stator give the motor a balance of inertia and output for compact axis assemblies.
