Product Description:

The MSK075C-0300-NN-M1-UG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It carries the 075 frame size with a C-length housing, uses a standard mechanical design, and features a plain shaft for direct coupling to precision loads. This layout fits machines that need predictable dynamic response without backlash from added transmission elements. Intended for positioning axes, packaging units, and gantry drives, the motor translates commanded current into tightly regulated rotary motion for repeatable industrial automation cycles.

Heat is removed by natural convection, so cabinet airflow alone maintains winding temperatures across an ambient range of 0 to 40 °C. Position feedback travels through the Hiperface interface, and the optical encoder divides one revolution into 128 signal periods for fine speed control. Its wiring plug can pivot through 240°, easing cable placement when space is limited. Because the feedback device is a multi-turn absolute encoder, it tracks multiple shaft turns and supports closed-loop motion where stable position data is needed after startup.

An electrically released holding brake supplies 23 Nm of static torque to secure suspended or high-inertia loads whenever the drive is disabled. The brake helps hold an axis at standstill when vertical loads or reflected inertia would otherwise allow unwanted movement. The housing achieves an IP65 protection rating, blocking dust ingress and low-pressure water jets on exposed machine frames. Thermal class 155 insulation permits sustained operation near rated temperature without compromising winding life, and winding code 0300 matches the electromagnetic characteristics expected by compatible IndraDrive controllers for efficient current use.
