Product Description:

The MSK100D-0300-NN-M2-AG0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It supplies controllable torque and speed to axes in industrial automation cells, allowing coordinated motion profiles that follow drive commands with high electrical efficiency and positional accuracy. When paired with a compatible drive, it can support positioning, transfer, and synchronized process axes that require repeatable rotary motion. Its operating role is to convert commanded current into controlled mechanical output for applications that demand consistent motion response over long duty cycles.

This model relies on natural convection for heat removal, so the mounting location must allow upward airflow around the stator housing during continuous duty. Feedback is provided through an EnDat2.1 interface that communicates bidirectionally with the controller, while the built-in optical scale delivers 2048 signal periods per revolution for incremental position feedback. Because the scanning system is optical, the position signal is not affected by magnetic fields. The encoder uses a multi-turn absolute design, so position remains available after power loss without a reference move. This motor is delivered without a holding brake, so static load retention must be handled by external mechanics or drive torque, and its shaft end uses a plain shaft for connection to couplings or pulleys.

The motor uses the increased concentricity design option, which reduces radial runout during rotation. The active length D works with the 100 frame size to set the electromagnetic envelope and torque behavior, while winding code 0300 identifies the coil configuration used by the matching drive. Power and protective earth conductors enter on the motor's A-side, which can simplify cable routing in compact machine layouts. This arrangement is useful where shaft alignment must remain stable for belt drives, couplings, or direct machine connections. It also helps keep the connection area predictable when surrounding equipment leaves limited installation space.
