Product Description:

The MSK071C-0300-NN-M1-BG0-NNAN synchronous servo motor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Serving as a direct-drive component in automated axes, it transforms controlled stator currents into accurately regulated torque and speed for coordinated motion in pick-and-place gantries, printing stations, and metal-cutting heads. The unit combines a low-runout mechanical design with the 0300 electrical winding so commanded positions can be reached with minimal radial error and without added gearboxes, while the housing and connector layout match standard IndraDrive cabling.

Thermal dissipation relies solely on natural convection, so airflow around the housing must remain unobstructed when the motor is mounted inside a machine frame. Position feedback is generated by a Hiperface-compliant optical encoder that resolves rotor angle into 128 signal periods per revolution, which supports smooth velocity loops at low speeds. Because the scanning system is a Multiturn Absolute type, the controller knows shaft position after power-up without an external homing routine. The motor is delivered without a holding brake, so external clamping must be provided if gravitational loads are present. This feedback arrangement supplies the phase information needed for dynamic torque control.

The motor has size 071 with length code C, giving a compact stack length that fits shallow mounting pockets. A plain shaft transmits torque directly to couplings, and the power lead exits on the B-side to keep cable routing parallel with drive panels. Sealing gaskets and axial O-rings establish an IP65 enclosure, allowing deployment in washdown or dust-laden work zones. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, while class 155 insulation supports typical servo duty cycles.
