Product Description:
The MSK071D-0300-NN-M1-AG2-NNAN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Designed for servo axes in packaging, metal-forming, and material-handling lines, this motor converts controlled input current from an IndraDrive controller into precise rotational motion. The product combines permanent-magnet excitation with high-resolution feedback so that the drive can command exact speed ramps, hold static positions, and execute repetitive indexing without mechanical backlash compensation. This operating principle helps automated equipment maintain repeatable positioning during frequent start-stop cycles and varying load conditions. Its sealed construction permits installation directly on machine frames exposed to lubricants and airborne particulates.
Thermal management relies on natural convection, which meets the series FN cooling arrangement without external fans or liquid channels; heat is transferred from the stator to ambient air through the finned housing. Position data are supplied over the Hiperface serial interface using an optical encoder that provides 128 signal periods per revolution, enabling fine interpolation inside the drive for smooth low-speed motion. An electrically released brake rated at 30 Nm secures the load during power loss and helps hold vertical axes at standstill. The enclosure carries an IP65 rating, blocking dust ingress and protecting internal components from low-pressure water jets encountered during machine cleaning.
A plain shaft transmits torque through clamping or keyed couplings without introducing axial preload. The frame code 071 indicates a compact cross-section that simplifies mounting in crowded servo clusters. Continuous service is permitted at ambient temperatures from 0 to 40 °C. Insulation class 155 supports winding temperatures up to 155 °C, providing thermal headroom for short overloads during rapid acceleration profiles. The motor also uses reduced runout design, multi-turn absolute feedback, and an A-side power connector to support accurate alignment and stable cable routing on the machine.
