Product Description:

The MSK071E-0300-NN-S3-UP0-NNNN servomotor is manufactured by Bosch Rexroth Indramat and is part of the MSK IndraDyn S Synchronous Motors series. It serves as a direct-drive actuator for packaging lines, pick-and-place gantries, and machining centers where precise velocity and rapid position loops are required. A permanent-magnet rotor and integrated feedback element allow the connected drive controller to command exact torque so multiple axes can remain synchronized during complex motion profiles.

This model relies on natural convection to move heat away from its stator, eliminating the need for fans or external coolant circuits and simplifying cabinet layout. The feedback harness attaches to a header that is rotatable through 240°, giving flexibility when routing encoder cabling in tight enclosures. Position data are exchanged over the Hiperface digital interface, and the internal sensor delivers a resolution of 16 signal periods per revolution through a capacitive scanning method that is immune to dust and magnetic fields. Mechanical dimensions follow motor length E, while winding code 0300 sets the electromagnetic properties used by matching IndraDrive amplifiers for correct current limits and commutation.

The unit ships without a holding brake, so static load retention must be handled by the drive or an external lock. A protection rating of IP65 seals the housing against dust ingress and low-pressure water jets, making it suitable for typical factory wash-down zones. The output shaft is a shaft with keyway, allowing torque transfer through keyed hubs without relying on friction alone. Continuous operation is approved within an ambient range of 0–40 °C; inside this window the insulation system, classified as thermal class 155, maintains winding integrity. The standard mechanical design and motor size 071 keep overall dimensions compact while still providing the dynamic torque demanded by modern automation.
