Product Description:

The MSK071C-0450-NN-M1-UP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive current into precisely timed mechanical torque, allowing closed-loop position and velocity control in industrial automation cells. Because the housing follows the series standard design, it can be mounted directly to machinery or within compact machine layouts, supporting applications such as indexing tables, Cartesian robots, and compact machining modules.

This model is cooled by passive surface airflow through natural convection, which reduces noise and eliminates the need for forced ventilation. The feedback plug is rotatable through 240°, which simplifies cable routing in tight layouts and helps prevent strain on the connector. Position data travel over the Hiperface interface, allowing bidirectional parameter exchange between the motor encoder and the drive controller. Inside the encoder, an interpolated track supplies 128 signal periods per revolution for smooth velocity control. Sensing is carried out with an optical scanning system, which maintains positional accuracy without magnetic hysteresis. Additional mechanical parameters include motor size 071 and length code C, which set the frame dimensions and stack height.

The encoder records absolute position across multiple turns with multi-turn absolute capability, so the axis does not require a homing routine after power-up. The unit is supplied without a holding brake, so any stationary load must be secured by drive torque or an external brake. Power is transmitted through a shaft with a keyway, which provides positive mechanical engagement with pulleys or couplings and helps prevent slip under cyclic torque. The winding code 0450 gives the electrical values used for drive sizing and thermal calculations.
