Product Description:

The MSK100B-0400-NN-M2-AG1-RNNN is an IndraDyn S synchronous servomotor supplied by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In positioning or velocity-controlled axes, this motor converts electrical power from a compatible drive into precise rotary motion for packaging machinery, gantry stages, and other automation equipment. Its mechanical layout follows an increased concentricity design, so shaft runout stays low and consistent during operation. That layout supports accurate feedback from the integrated optical encoder during closed-loop position and speed control. It is intended for precise, repeatable motion in servo systems where stable feedback is important to axis accuracy.

The motor is cooled by natural convection, removing the need for external fans and allowing quiet installation. Position data is generated by an optical encoder that communicates through the EnDat2.1 serial interface, and its scale provides 2048 signal periods that the drive interpolates for fine resolution. Because the feedback device is multiturn, it preserves revolution counts when power is removed, and the electrically released holding brake applies 32 Nm to lock the shaft during standby. An IP65 housing protects the windings against dust and water jets, while the plain shaft simplifies direct coupling to gearboxes or drive pulleys where a keyed output is not required.

The permissible ambient range is 0 to 40 °C, and the insulation system uses class 155 materials for continuous operation within the motor's thermal limits. Length code B and frame size 100 set the active stack height and stator diameter for this motor size, which gives it a balance between torque and rotor inertia for midsize servo axes. Winding code 0400 identifies the electrical winding used with compatible drive inverters. Power wiring exits on the A-side of the housing to simplify machine cable routing, especially where cable carriers or cabinet entries are arranged on one side.
