Product Description:

The MSK101C-0300-FN-S2-AG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a torque-dense, closed-loop drive element, it delivers precise rotary motion for positioning axes, gantries, and processing spindles in automated machinery. The size 101 housing and length code C balance continuous torque with a compact footprint, making the unit a common choice for multi-axis packaging lines, metal-cutting centers, and assembly systems.

This model uses liquid cooling to route thermal energy away from the stator, allowing higher current loading at lower ambient temperatures than air-cooled variants. The rotor and stator are built with increased concentricity to limit mechanical runout and maintain smooth velocity feedback. An EnDat2.1 interface carries high-resolution position data to the drive, and its absolute optical encoder generates 2048 signal periods per revolution for fine commutation. The sensing system relies on optical scanning of a code disc, which resists magnetic interference and promotes repeatable accuracy. Because the encoder is single-turn, it reports absolute shaft position within one revolution, while multi-turn tracking is handled by the controller or external battery modules.

The mechanical end of the shaft is supplied without a holding brake, so any static load retention must be provided by external clamping or by drive torque. A plain shaft eliminates keys or splines, supporting backlash-free coupling hubs in precision stages. Power conductors exit on the motor’s A-side, simplifying cable routing when the housing is mounted to right-hand machine frames. The electromagnetic section follows winding code 0300, which sets the copper fill, resistance, and inductance values expected by matched IndraDrive inverters.
