Product Description:

The MSK101C-0300-NN-S1-AG0-NPNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Intended for closed-loop motion axes, the motor converts electrical energy from a drive converter into accurately controlled torque for positioning tables, packaging stations, and other automated equipment. Its 101 frame size provides mounting compatibility with existing IndraDyn assemblies while keeping a compact footprint for multi-axis cells. When used on indexing axes, it supports controlled acceleration and deceleration so repeated positioning cycles remain stable throughout operation. This operating behavior is useful on machines that require smooth motion between short dwell periods.

Heat generated by the windings is removed solely by natural convection, so no external fan or liquid path is required. The housing uses a B5 flange assembly, allowing direct bolting to gearboxes or machine plates. Position feedback travels through the Hiperface interface; this bidirectional link sends encoder data and stores motor parameters. An optical scanner produces 128 signal periods per mechanical revolution, giving fine incremental and absolute data. Motor length C balances inertia against torque, while winding code 0300 sets the electrical limits for medium-duty work. Thermal class 155 insulation supports elevated winding temperatures, and the power connector sits on the A-side for consistent cable routing.

Because the encoder is a single-turn device, the absolute position resets after 360°, which is adequate for rotary axes that home at startup. An IP65 enclosure rating seals the stator against dust ingress and low-pressure water jets, so the unit can be mounted outside the control cabinet. The operating envelope spans 0–40 °C, matching typical plant floor conditions without derating. Torque is transmitted through a plain shaft that mates with compression couplings, and the lack of a keyway reduces hub imbalance at high speed. The motor is supplied without a holding brake, so static locking must be provided by the drive or external mechanics.
