Product Description:

The MSK071E-0300-NN-S1-AP0-NNAN synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop axis drives that demand accurate velocity and position control, such as pick-and-place gantries or form-fill-seal machinery. Coupled to an IndraDrive amplifier, the motor converts regulated three-phase power into repeatable mechanical output, providing the actuation point for automated production sequences.

Thermal management relies on natural convection, allowing heat to leave the stator without forced airflow. The mechanical build is graded for reduced runout, minimizing radial displacement at the shaft to keep coupling loads predictable. Position feedback is supplied through a Hiperface interface, which carries both incremental and absolute data to the drive. An integrated optical scale delivers 128 signal periods per revolution, enabling fine interpolation inside the controller. The scanning method is optical, so the encoder maintains accuracy in high-current zones near the windings and supports high-bandwidth servo loops that benefit from precise phase information.

In operation, the encoder’s measuring range is confined to one mechanical revolution, so single-turn feedback simplifies homing routines on indexing tables that do not exceed 360 degrees of travel. Torque is transferred through a shaft with a keyway, ensuring that hubs or pulleys do not slip during startup acceleration. The frame code of 071 indicates the stator diameter, while the extended stack designated as motor length E increases continuous torque density without altering mounting geometry. Electrical characteristics follow winding code 0300, which gives the resistance and inductance expected by Rexroth drive algorithms. Power wiring exits from the A-side connector, and the motor is supplied without a holding brake, so static loads must be restrained by external clamping or drive torque.
