Product Description:

The MSK101E-0300-FN-S3-AG2-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It provides precise torque and velocity control for automated axes in machining centers, packaging stations, and robotics. When paired with a compatible IndraDrive controller, the motor supports closed-loop operation that helps maintain commanded position during rapid load changes. Its synchronous design also supports responsive motion on axes that must accelerate, decelerate, and reverse direction without losing control accuracy. This behavior is useful in equipment that depends on repeatable positioning and stable speed regulation during continuous production cycles.

This model uses liquid cooling, so heat is carried away through an external coolant circuit instead of ambient airflow. Because heat removal does not depend on surrounding air, the motor can be integrated into compact machine sections where fan-driven ventilation is limited. Feedback is transmitted through a Hiperface interface, which sends position and commutation data to the drive for controlled motor operation. Inside the encoder, the system provides 16 signal periods per mechanical revolution and uses capacitive sensing, which helps reduce sensitivity to magnetic interference. Because the encoder is single-turn, it reports absolute position within one shaft revolution, while additional turn tracking must be managed by the control system. An electrically released holding brake provides 70 Nm of static torque to hold the shaft when power is removed or motion must be stopped.

The frame designation 101 indicates the motor size, and length code E indicates a longer active core for increased continuous output within this frame. Power connections are arranged on the A-side, which can simplify cable routing when the motor is mounted along a machine bed or enclosure wall. The plain shaft avoids a keyway, making it suitable for clamp or shrink-fit hubs that depend on accurate concentric alignment. Winding code 0300 identifies the electrical winding used by the matching drive for current control and motor tuning. The motor has a standard housing design, and it should be installed with access to the liquid manifold so coolant connections remain reachable after installation.
