Product Description:
The MSK050B-0600-NN-S2-UP1-RNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It belongs to the IndraDyn S line of brushless AC motors that convert drive output current into precise rotary motion for packaging stations, pick-and-place heads, and light machining axes. The unit pairs with IndraDrive controllers, where its integrated encoder returns rotor position so the drive can regulate current and maintain commanded speed or torque under changing load conditions. This operating profile suits repetitive automation tasks that require frequent starts, stops, and accurate position correction during each machine cycle.
Heat from the stator is dissipated by natural convection, so no external fan or liquid circuit is required and the motor can be installed where simpler cooling is preferred. Position data are supplied through an optical measuring system that generates 2048 signal periods per revolution, which supports smooth velocity regulation at low speeds and stable response during small position changes. The encoder communicates over the bidirectional EnDat2.1 protocol, and its connector is rotatable through 240° to simplify cable routing when clearance around the housing is limited. The 050 frame diameter, B-length stack, and 0600 winding are arranged to match compatible IndraDrive power stages for servo applications in the motor’s size class.
The output uses a shaft with a keyway to provide positive drive engagement and help prevent slip during reversing duty or rapid acceleration changes. For power-off holding, an electrically released brake can exert 6 Nm of static torque, allowing vertical or indexing axes to remain locked without continuous drive current. The feedback unit is a single-turn device, so absolute position is available within one revolution while the controller manages turn counting for extended travel. The rotor and flange are built to an increased concentricity standard, which helps reduce coupling runout and supports smoother alignment with connected mechanical components.
