Product Description:

The Bosch Rexroth Indramat MSK076C-0300-NN-M2-UG0-RSNN belongs to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it supplies regulated rotary motion for positioning tables, gantry axes, and processing spindles that depend on high-resolution feedback. The motor works with IndraDrive amplifiers to translate controller commands into precise torque for modern industrial automation lines.

The unit relies on natural convection for heat removal, so the housing should be mounted where free airflow is available. Position data are obtained through an optical encoder that communicates by EnDat2.1 and provides 2048 signal periods per mechanical revolution, while the optical scanning principle helps keep interpolation error low. Because the motor is supplied without a holding brake, external clamping devices are required if loads can descend or coast when power is removed. A protection rating of IP65 helps shield internal components from dust and low-pressure water jets. The stator uses winding code 0300 and Class 155 insulation, allowing high winding temperatures during transient peaks.

The feedback connector is rotatable through 240°, which lets the cable exit be aimed toward the cabinet entry point without stressing the conductors. Absolute multi-turn tracking is maintained by the encoder's multiturn absolute function, so position is available immediately after an emergency stop or power cycle. Power is transmitted through a plain shaft, so the coupling must provide axial retention and keyless torque transfer. Continuous operation is permitted at ambient temperatures from 0 to 40 °C; above this range, current derating is required to stay within the thermal limits of the winding and insulation system. Size 076 and length C indicate the motor's frame dimensions, and the design includes increased concentricity to help reduce vibration as well as integrated explosion protection for use in classified areas.
