Product Description:

The MSK101C-0300-NN-S3-FG0-NPNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It provides closed-loop rotary motion for automated axes and can be coupled directly to gear trains, linear actuators, or production spindles while being driven by IndraDrive servo amplifiers. The closed-loop arrangement lets the paired drive correct load changes during acceleration, deceleration, and steady-speed operation. This motor type is suited to applications that need repeatable speed regulation and accurate positioning over frequent duty cycles.

The motor uses B5 flange mounting and transmits torque through a plain shaft, which helps align the output directly with connected machine elements. Incoming power and feedback conductors terminate in a terminal box, which supports rigid-conduit wiring and keeps cable entry organized at the housing. Heat is removed by natural convection, so no external blower or liquid circuit is required during normal operation. The housing has an IP65 rating that helps block dust ingress and low-pressure water jets in general industrial areas. The motor has size 101 and length code C, which indicate a larger frame and longer stack for this model, and it uses insulation class 155 for continuous-duty winding temperature limits.

Position feedback is supplied through a Hiperface interface, and the single-turn encoder resolves each mechanical revolution into 16 signal periods. The feedback system uses capacitive scanning, which avoids magnetic sensing and supports stable signal generation in electrically noisy environments. The motor is delivered without a holding brake, so stationary load retention must come from drive torque or external mechanics. Rated service is limited to ambient temperatures of 0–40 °C, helping natural cooling keep winding temperature within the permitted range. Because the encoder is single-turn, the control system must reference absolute position across multiple revolutions through its own homing routine at startup.
