Product Description:

Bosch Rexroth Indramat manufactures the MSK075C-0300-NN-M1-UG2-NNNN servomotor for the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servomotor converts electrical energy into controlled rotary motion for automated packaging lines, pick-and-place modules, and other positioning applications. By combining permanent-magnet excitation with sinusoidal commutation, the motor supplies smooth torque and precise speed regulation while occupying a compact standard frame that integrates directly with IndraDrive converters.

To hold an axis at rest, the electrically released brake supplies 30 Nm of static torque, removing the need for external clamps during machine shutdowns. The housing carries a IP65 ingress rating that prevents dust entry and resists water projected from any direction. Feedback is supplied by an optical encoder that communicates through the Hiperface interface, and drive electronics receive multiturn absolute position information as well as electronic nameplate data across this bidirectional channel. The same encoder resolves mechanical rotation into 128 signal periods, giving the controller enough granularity for tight velocity loops. Cable exits are simplified because the feedback connector swivels through 240°, permitting alignment with existing harness runs. Heat generated by the 0300 winding is managed under the FN cooling class, and the C length body within the 075 frame delivers the torque density expected for mid-range servo axes.

The motor operates within an ambient window of 0–40 °C, so panel ventilation must keep temperatures inside that range. Its cooling method is natural convection, eliminating fans and relying on surface airflow around the stator. A plain shaft transmits torque directly to clamp hubs or couplings and helps maintain concentricity in high-precision stages. Insulation system class 155 supports elevated winding temperatures without insulation breakdown during cyclic duty.
