Product Description:
The MSK103A-0300-NN-S2-UG1-NNNN synchronous servomotor is produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. In automated production lines, this motor works with a suitable drive controller to generate precise rotary motion for axes that position tooling, conveyors, or robotic joints. The IndraDyn S design emphasizes compact dimensions and high torque density, allowing the unit to fit into enclosed machine spaces while still supporting accurate speed and position control. Its operating role is well suited to applications that require repeatable motion, stable servo response, and dependable integration with closed-loop control hardware.
Thermal management relies on natural convection, so heat is dissipated through the housing without external air or liquid assistance. The feedback wiring exits through a connector that is rotatable through 240°, giving more freedom when routing cables around nearby machine components. Position data travel over the EnDat2.1 digital interface, which sends absolute values and diagnostic information directly to the drive. Within the encoder, 2048 signal periods are generated optically, which allows fine interpolation for precise motion control. Because the sensing principle is optical, the feedback system supports stable position detection during repeated starts, stops, and extended idle periods.
For load-holding duties, the electrically released brake supplies 33 Nm of static torque, helping a vertical axis remain in place when drive power is removed. The housing is sealed to IP65, which helps keep out dust and low-pressure water jets commonly found in industrial areas. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, making the motor suitable for standard climate-controlled factory conditions. Internal insulation follows class 155, allowing the winding system to withstand elevated operating temperatures within its thermal class. This combination of brake capacity, enclosure sealing, temperature range, and insulation class supports steady use in packaging, handling, and general automation equipment.
