Product Description:

The MSK101E-0300-FN-M1-LG2-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It functions as an IndraDyn S servomotor for closed-loop machinery that requires repeatable speed and accurate positioning in industrial automation. Typical applications include press feeders, pick-and-place robots, and tool spindles where consistent motion response is required. The 101 frame with E length provides a compact motor package, and the housing is suited for direct connection to compatible planetary gearboxes and Rexroth drive controllers.

Cooling is managed by liquid cooling, allowing the stator to remove heat through a plate or jacket while keeping operating noise low. The electrically released brake provides 70 Nm of holding torque and helps secure vertical loads when power is removed. The enclosure is rated IP65, which helps protect internal components from dust and water jets commonly found on production floors. Position feedback comes from an optical encoder with 128 signal periods per revolution, giving the drive interpolate-ready data for motion control. Safe operation is permitted at ambient temperatures of 0–40 °C, which covers the normal range for many factory environments.

Feedback is transmitted over the Hiperface serial interface, allowing digital communication between the motor sensor system and the drive. The encoder provides multiturn absolute feedback, so position information remains available across multiple mechanical revolutions without battery support. Mechanical output is transferred through a plain shaft, which simplifies coupling alignment and avoids key-related imbalance. Winding code 0300 sets the voltage constant and rated current expected by the compatible drive. A left-side power connector supports clean cable routing in multi-axis cabinets where installation space is limited.
