Product Description:

The MSK050C-0300-NN-S1-UP1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is used to produce controlled rotary motion in automated machine axes, pairing with Rexroth drive controllers for position, velocity, and torque regulation in industrial automation lines. Its servo design supports repeatable acceleration and stable speed control in packaging, handling, and indexing equipment.

This model relies on natural convection for heat dissipation, so no external blower or liquid circuit is required when surrounding airflow is sufficient. Feedback is handled by an optical encoder that communicates through the Hiperface interface, and the encoder delivers 128 signal periods per revolution for position tracking on mid-size axes. To simplify cable routing inside compact enclosures, the encoder connector can be rotated through 240°. The optical encoder provides accurate signal edges with low drift, and it uses a single-cable arrangement for power and data. This motor uses the standard design variant, so its external dimensions follow standard outlines and mounting patterns.

The electrically released holding brake generates 6 Nm of static torque, allowing the shaft to remain locked during power-off events or emergency stops without external clamping devices. Because the feedback element is single-turn, it reports absolute position within one mechanical revolution, while multi-turn counting must be handled by the drive. The motor uses winding code 0300, which corresponds to the electrical values expected by compatible drives. Mechanical coupling is through a shaft with a keyway, enabling rigid torque transfer to pulleys or couplings that follow DIN 6885 key dimensions. The motor has a frame size of 050 and C length, which balance torque density with a compact overall size for packaging machines, pick-and-place modules, and other medium-inertia axes.
