Product Description:

Bosch Rexroth Indramat produces the MSK071E-0300-FN-S1-UP2-NNNN servomotor for the MSK IndraDyn S Synchronous Motors series. This unit is an IndraDyn S synchronous servomotor intended to convert drive controller output into precise rotary motion for automated positioning axes, packaging stations, and material-handling equipment. It is suited for controlled motion tasks where the drive must regulate torque, speed, and position with high repeatability. The motor uses a size 071 frame with E length, giving it a mid-range mechanical envelope for servo applications that need compact dimensions and stable torque delivery.

The FN cooling designation indicates that the stator is intended for a heat-transfer circuit, and the motor uses liquid cooling to remove heat without external airflow. An internal keyway shaft transfers torque to the driven mechanism, while an electrically released holding brake provides 30 Nm of static torque when power is removed. The housing is sealed to IP65 to block dust and low-pressure water jets. Position feedback is transmitted through a rotatable 240° connector that carries the Hiperface interface, and the encoder provides 128 signal periods per revolution for closed-loop speed and position control. The 0300 winding code matches the electrical characteristics expected by compatible IndraDrive inverters.

The encoder uses optical scanning, and the feedback is single-turn, so absolute position is retained within one mechanical revolution. Insulation class 155 protects the coils against thermal aging during extended operation, and the rated ambient range is 0 to 40 °C. A liquid jacket surrounds the stator to support stable temperature management in enclosed machine spaces, and the standard housing fits common servo installations. The rotatable connector also helps with cable routing in dense multi-axis assemblies where clearance around the motor is limited.
