Product Description:
The MSK101E-0300-NN-S2-AP2-RNNN synchronous servomotor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is designed to deliver closed-loop torque and position control in industrial automation axes, supplying rotary power directly to machinery without mechanical gearing. By combining a compact electromagnetic design with optical feedback, the motor supports precise indexing, stable speed regulation, and coordinated multi-axis motion in packaging, printing, and material-handling equipment.
Thermal management is handled by natural convection, so installation must leave clearance around the housing to allow ambient airflow. Position feedback is exchanged through an EnDat2.1 interface, and the optical system provides 2048 signal periods for accurate interpolation in closed-loop control. Because the encoder is single-turn, absolute position is retained within one revolution after power-up. An electrically released holding brake supplies 70 Nm of static torque to secure vertical or overhung loads when the drive is disabled. The A-side power connection and the selected winding and length codes make the motor suitable for use with standard IndraDrive controllers.
The housing has a protection rating of IP65, which helps keep dust and low-pressure water out of the motor during operation. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, so hotter or colder conditions may require derating. The output uses a shaft with a keyway, which supports direct attachment to pulleys, couplings, or gearboxes without a custom hub. The winding system uses insulation class 155, allowing the motor to withstand elevated internal temperatures during repeated acceleration and deceleration cycles. This layout is well suited to compact machine axes that require accurate positioning and stable speed control over long operating periods.
