Product Description:

The MSK101C-0300-NN-M2-BG2-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit supplies closed-loop rotary motion for axes that require accurate speed regulation and repeatable positioning in packaging lines, printing presses, and material-handling cells. It is intended for integration into machine axes where a compatible drive manages current, speed, and position in real time. Its size 101 housing with length C places it in the medium-frame range for automation platforms that need a balance of torque capacity and installation flexibility.

Thermal management is handled by natural convection, so the motor operates without external fans. Feedback is delivered through an EnDat2.1 interface, and the optical scanning system provides 2048 signal periods for high-resolution position data to the drive. For static load holding, an electrically released brake applies 70 Nm of torque to the shaft. A sealing system rated at IP65 blocks dust and low-pressure water jets. The power connector is located on the B-side, which helps keep cabling at the rear of the machine frame. This arrangement can support cleaner cable routing where moving machine sections limit available space around the motor.

The servo is intended for ambient temperatures from 0–40 °C, and its windings use class 155 insulation materials for continuous duty. The encoder supports multiturn absolute position tracking, so the drive can report rotor angle over many revolutions after power cycling. Winding code 0300 matches the motor to compatible current-rated inverters. The rotor geometry is manufactured with increased concentricity to reduce runout on the plain shaft. The plain shaft allows direct coupling to gearboxes or belt pulleys without a keyway, and this shaft style also works well with clamping hubs.
