Product Description:

The MSK050B-0300-NN-S1-UG0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In industrial automation, this motor supplies tightly regulated torque and speed for pick-and-place axes, form-fill-seal stations, indexing units, and other motion modules that require high repeatability during frequent starts, stops, and direction changes. It is intended for closed-loop servo applications where stable speed regulation and accurate positioning are required throughout the operating cycle. Power is transmitted through a plain shaft, which supports backlash-free clamping couplings in compact drive trains and suits assemblies where keyed connections are not required.

Thermal management relies on natural convection, so external fan assemblies are unnecessary when the installation provides adequate surrounding airflow. This cooling method keeps the housing simple and avoids extra blower hardware around the axis. The motor has a Standard design, which means the housing uses the normal MSK construction without optional sealing or reinforced flanges. A frame size of 050 gives the motor the matching mechanical envelope for this platform, while the B length provides a moderate active stack depth for mid-range torque in packaging and handling equipment. Winding code 0300 identifies the electrical winding layout used with compatible IndraDrive controllers and supports the current and voltage characteristics expected by the drive.

Feedback connections use a rotatable 240° connector, allowing the cable outlet to be positioned to suit the machine layout without twisting the conductors during installation. Electrical signals are transmitted through the Hiperface interface, and the optical encoder provides 128 signal periods per mechanical revolution for motion feedback in closed-loop operation. The single-turn measuring system reports the absolute shaft angle within one revolution, so the drive receives position data immediately after power-up and can maintain accurate commutation. The optical feedback system also supports precise rotor position detection across the speed range for smooth servo response. The motor is supplied without a holding brake, so any load that must remain fixed at standstill requires drive torque or an external holding device.
