Product Description:

The MSK071E-0300-FN-M1-UG2-NNNN is a rotary servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit interfaces with IndraDrive controllers and delivers finely controlled torque for indexing tables, pick-and-place gantries, and other precision axes. By combining permanent-magnet excitation with internal position feedback, it converts electrical energy into mechanical rotation while maintaining accurate speed synchronization with commanded motion profiles across continuous or cyclic duty cycles.

The motor uses size 071 with the extended length code E, and winding code 0300 identifies the winding configuration used in this frame. Operation relies on the FN cooling requirement, implemented through an internal liquid jacket. This Liquid cooling extracts heat directly from the stator so rated output can be sustained without additional airflow. The encoder connector is mechanically indexed so the cable can be swiveled through 240°, simplifying cabinet layout in tight spaces. Position data is transmitted over the Hiperface interface, and the optical scanning head resolves 128 signal periods per mechanical turn. Position sensing is Optical, and the device stores absolute position across power cycles with a Multiturn Absolute track that eliminates homing moves after shutdown.

The servomotor incorporates an electrically released brake that clamps the rotor with 30 Nm of holding torque, securing vertical loads during power loss and preventing drift before motion commands resume. A Plain shaft without a keyway is provided so coupling elements can be shrink-fit or clamped, reducing concentricity errors in high-precision assemblies. The mechanical housing follows the Standard design variant, allowing the motor to align with commonly used MSK mounting flanges and liquid inlet ports.
