Product Description:

The Bosch Rexroth Indramat MSK100B-0300-NN-M2-BG0-RNNN is a synchronous servo motor in the MSK IndraDyn S Synchronous Motors series. It drives closed-loop motion axes that require quick positioning, steady speed regulation, and repeatable torque in packaging lines, material-handling gantries, and other automated stations. Its synchronous design supports responsive acceleration and stable operation during indexing and continuous-duty cycles. That behavior is useful on axes that repeat starts, stops, and dwell positions throughout a production cycle.

Heat is dissipated through natural convection, so airflow around the frame must stay unobstructed to maintain rated current without forced cooling. Feedback is supplied by an optical encoder that communicates over the EnDat 2.1 protocol, and this point-to-point link transfers absolute position data to the drive after every power-up. The encoder provides 2048 signal periods, allowing the controller to support smooth commutation and accurate motion control. Because the tracking element is multi-turn absolute, machine homing cycles are unnecessary after a power interruption. A B-side power connector places the motor phases on the non-drive end for easier cable routing, and the housing has an IP65 rating for protection against dust and water jets.

The rotor and stator are produced with increased concentricity, which helps minimize radial runout and supports consistent magnetic air gaps when the motor is paired with precision gear stages. The motor uses a plain shaft, which provides a smooth cylindrical output surface for direct coupling. This shaft style is often used where couplings rely on clamping force rather than a keyed connection. It uses class 155 insulation, so the winding system can tolerate elevated internal temperatures during normal operation. The ambient temperature range for continuous duty is 0 to 40 °C.
