Product Description:
The MSK075C-0300-NN-M1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts controlled electrical energy into precise rotary motion for positioning, contouring, and velocity-regulated tasks in automated machinery. Close coupling with IndraDrive controllers supports tight motion loops for packaging stations, tool changers, and material-transfer axes in industrial automation. Its synchronous design helps the drive maintain accurate speed and position response during repeated start, stop, and indexing cycles.
Heat is removed by natural convection, so the frame relies on surface exposure instead of forced airflow. The stator uses winding code 0300, which matches mid-range current requirements in the MSK motor range. A sealed housing rated IP65 helps keep dust and low-pressure water jets away from internal components. Torque is delivered through a plain shaft, which works well with gearboxes or timing pulleys that do not require a keyway. Command and diagnostic data are exchanged through the Hiperface interface, allowing feedback signals and motor operation data to be handled through a compact connection path. The motor has frame size 075 and motor length C, giving it a compact footprint for machine layouts with limited installation space.
Position feedback is provided with 128 signal periods of optical resolution processed by a multi-turn absolute encoder, so rotor position remains available after power loss. The encoder connector can be rotated by 240 degrees, which helps with cable routing where panel clearance is limited. Continuous duty is permitted in ambient temperatures from 0 to 40 °C, and the windings meet thermal class 155 for insulation performance. The motor is supplied without a holding brake, which reduces inertia for axes that use an external locking method. Optical feedback helps reduce jitter during low-speed movement and supports stable position control in applications that require smooth, repeatable motion.
