Product Description:

The MSK075C-0300-NN-S1-UP1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated assembly cells, packaging lines, or metal-cutting machines, it provides closed-loop torque and speed control. This allows it to drive feed axes, spindles, and auxiliary positioning tasks that require accurate, repeatable motion. The motor is suited to applications that need responsive acceleration and stable speed regulation across repeated operating cycles.

Cooling is handled by natural convection, so no external fan is required, while winding code 0300 and the standard design support thermal balance during continuous cyclic duty. The aluminum housing carries an IP65 rating that blocks dust and low-pressure water jets, allowing the motor to be mounted on exposed machine frames in typical industrial environments. An electrically released holding brake produces 23 Nm of static torque to prevent axis drift during power-off conditions and to secure vertical loads. Position and speed data are generated by an optical Hiperface encoder, and a keyed shaft transfers torque directly to couplings with minimal backlash. Frame size 075 and length C set the mechanical proportions and active length for this configuration.

The motor is intended for ambient temperatures from 0 to 40 °C. Windings insulated to class 155 tolerate elevated internal heat without degrading varnish or insulation integrity. For flexible cable routing, the feedback connector can swivel through 240°, which helps when space around the motor is limited. The encoder operates as a single-turn device, so one absolute position is available per revolution. Its resolution of 128 signal periods per turn supports fine interpolation when the drive performs micro-positioning moves.
