Product Description:
The MSK071D-0300-NN-M3-UG1-NNNN servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It supplies controlled rotary motion for industrial automation, converting drive current into torque with feedback that supports coordinated multi-axis tasks on assembly stations and material-handling equipment. The unit’s standard housing makes it a direct fit for medium-power axes where high positional accuracy is required. Its layout is suited to applications that need repeatable motion, steady speed control, and consistent positioning across frequent start-and-stop cycles.
Cooling for the motor is handled by natural convection, so the enclosure relies on ambient airflow rather than forced fans or liquid jackets. The housing carries an IP65 rating that helps protect internal components from dust and low-pressure water jets. Continuous operation is specified for ambient conditions between 0 to 40 °C, supporting stable thermal behavior in typical machine spaces. The electrically released holding brake delivers 23 Nm of static torque, allowing loads to remain fixed when drive power is removed. Mechanical power is transferred through a plain shaft, and cable entry is simplified because the encoder connector is rotatable through 240°, which helps route the plug away from nearby obstructions without placing unnecessary stress on the conductors.
Signal quality is maintained by the Hiperface interface, which transmits absolute position data from a measuring system with 16 signal periods. Position detection relies on a capacitive scanning method, which is well suited to environments where magnetic contamination could interfere with other sensing principles. The feedback device is multi-turn absolute, so the controller receives unique angle information across several revolutions without requiring a homing routine after startup. Internally, winding set 0300 matches the drive’s current tables, and insulation class 155 protects the copper from heat rise associated with frequent starts. The 071 frame size follows the mounting geometry used for this motor platform, while length code D provides a balance between inertia and output torque for responsive servo operation.
