Product Description:
The MSK101E-0300-NN-M2-AG0-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, the unit converts drive controller commands into rotary motion for precise positioning tasks in packaging lines, printing machines, and material-handling axes. The model is built around the MSK electromagnetic platform but uses an E-length stator that increases torque potential while keeping the frame compact. Its plain output shaft mates directly with couplings or gearboxes to transfer torque without mechanical backlash. This layout suits axes that need repeatable motion and stable torque delivery during frequent starts, stops, and speed changes.
Cooling is provided by natural convection, so heat released by the windings dissipates through the housing without forced airflow. A protection rating of IP65 seals the stator against dust and water jets, while the shaft seal area requires normal maintenance. Position data are captured by an optical feedback system that combines 2048 signal periods of resolution with the EnDat 2.1 digital interface, allowing high-speed bidirectional communication with Rexroth HCS or IndraDrive controllers. The motor maintains performance across an ambient range of 0–40 °C, making it suitable for typical indoor production areas. This feedback arrangement supports accurate speed regulation and position control during dynamic axis movement.
The encoder stores absolute position over multiple turns, and its multi-turn absolute format removes homing cycles after power-up. Dynamic concentricity is improved by the increased concentricity design, which helps reduce radial runout as the rotor accelerates. The unit is built on size 101 laminations with an internal winding code 0300 that sets the resistance and inductance values used for matched drive tuning. Thermal limits correspond to insulation class 155, and operation without a holding brake allows the shaft to spin freely when de-energized. Power and feedback connectors are placed on the A-side to simplify wiring in tight cabinets.
