Product Description:
The MSK071D-0300-NN-M1-UG1-NNNN is a servo motor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. As a compact rotary actuator, it converts drive currents from an IndraDrive controller into precise torque for positioning or velocity-regulated axes in packaging, printing, or material-handling stations on automated lines. The equipment integrates tightly with standardized mounting flanges and cable sets already present in Rexroth drive packages.
Mechanically, the unit falls within 071 frame size and the extended D length category, giving a stator depth that increases continuous torque without enlarging the mounting interface. Its stator is wound to pattern 0300, a code that defines resistance and inductance matching IndraDrive current loops. A plain shaft transmits motion without keyway stress risers, and the overall design is listed as standard, so no special coating or sealing package is added. Heat is removed by natural convection, eliminating the need for forced air or liquid circuits. For fail-safe stops, an electrically released holding brake supplies 23 Nm of static torque, allowing vertical axes to stay fixed when power is cut.
Position feedback relies on an Hiperface optical encoder that provides 128 signal periods per revolution and captures multi-turn angle data through a Multiturn Absolute counting system. The sensing path is Optical, so interpolation accuracy stays stable across temperature swings, and the encoder connector can be rotated through 240°, simplifying cable routing inside tight cabinets. By combining the high-resolution feedback with the thermal behavior discussed earlier, the motor can maintain fine velocity loops without additional sensors while its passive cooling keeps acoustic noise low. These characteristics shorten commissioning times and support repeatable motion profiles in continuous-duty production cells.
