Product Description:

Bosch Rexroth Indramat manufactures the MSK050C-0300-NN-M1-UP0-NSNN within the MSK IndraDyn S Synchronous Motors series. The unit is an AC servomotor that delivers precise torque and speed regulation for coordinated motion in packaging machines, gantry axes, and automated handling stations. By converting drive inverter output into repeatable rotary motion with integrated feedback, it links the electrical command layer to the mechanical load and helps keep positional error low during continuous duty. That operating behavior is useful on indexing tables and transfer systems where smooth acceleration and repeatable stopping are required through frequent start-stop cycles.

Cooling relies on natural convection, so the motor should be installed where ambient air can circulate freely. A housing rated IP65 helps block dust and low-pressure water jets for use on open machinery. Position data are transmitted through the Hiperface interface, which supports feedback exchange between the motor and the drive without separate external sensor hardware. An optical disc generates 128 signal periods per revolution before interpolation for high-resolution speed control. The encoder is a multi-turn absolute device, so the axis can start with position information already available after power-up. A rotatable connector with 240 degrees of adjustment helps simplify cable routing when space around the motor is limited.

The mechanical interface uses a shaft with a keyway, so torque can be transferred directly to pulleys or couplings. Thermal capability follows insulation class 155, allowing winding temperatures up to 155 °C. Rated operation covers ambient temperatures from 0 to 40 °C; outside this range, continuous output is derated or external cooling is required. Electrical behavior corresponds to winding code 0300, which is matched to medium-torque IndraDrive inverters. Motor size 050 and length C keep the frame compact for closely spaced multi-axis arrangements. Because the motor does not include a holding brake, any load that must remain fixed at standstill has to be secured by the machine design or by controlled drive torque.
