Product Description:

The MSK100A-0450-NN-S1-AG1-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into controlled rotary motion for industrial automation tasks such as indexing tables, gantry axes, or packaging lines. The motor is delivered in a standard mechanical design, and its electrically released holding brake secures the load when power is removed while still allowing quick starts once the brake coil is energized. It is suited for repeated start-stop motion where stable torque delivery and accurate feedback are required throughout the operating cycle.

The integrated encoder employs the Hiperface protocol to transmit absolute rotor data and diagnostic information to the connected drive. It delivers 128 signal periods per mechanical turn through an optical scanning head, and as a single-turn device, position is resolved within one revolution. A plain shaft promotes uniform torque transfer to the coupling hub and avoids the backlash that can occur with keyed interfaces. When the drive is de-energized, the brake provides 32 Nm of static holding torque to help restrain vertical or suspended loads.

Heat is dissipated by natural convection, so airflow around the stator fins must remain unobstructed to maintain temperature limits during continuous operation. Mains power enters through an A-side connector, allowing cable routing to follow the machine frame rather than cross moving axes. The housing corresponds to size 100, and the length class A keeps overall depth low for installations with restricted space. Stator winding code 0450 indicates the electrical characteristics used by the drive for current control and dynamic torque response. The motor also uses the standard enclosure layout of this product line, which supports compact servo installations that require direct feedback integration and straightforward mechanical placement.
