Product Description:

The MSK071E-0303-FN-M1-UG2-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This standard-design unit uses a plain shaft to couple directly to driven machinery and is built on the 071 frame size. In closed-loop industrial automation, it converts drive output from an IndraDrive controller into precisely metered rotary motion for positioning tasks on packaging lines, pick-and-place gantries, and tool axes. Its synchronous motor design supports accurate speed control and responsive torque delivery during repeated start-stop cycles.

The motor uses the FN cooling arrangement, so it must be connected to a coolant circuit that circulates through its stator jacket; this liquid cooling keeps winding temperature stable during continuous duty. The electrically released holding brake delivers 30 Nm of static torque, locking the axis whenever power is removed. A housing-mounted connector that is rotatable 240° simplifies cable routing in tight cabinets. Position data travel over the Hiperface interface, supporting fast commutation alignment after power-up. A sealed enclosure rated IP65 blocks dust and low-pressure water jets, allowing the servomotor to operate directly on machine frames without additional covers.

An optical sensor inside the encoder head produces 128 signal periods per revolution, and multi-turn absolute position tracking preserves shaft position across power cycles for up to 4096 turns. The insulation system has a class rating of 155, which supports elevated internal temperatures without early varnish breakdown. Performance remains stable when ambient air stays between 0 to 40 °C; outside this range, the motor may require derating or additional cooling. The E-length stator stack provides higher torque than shorter versions, while the standard mechanical layout keeps mounting and integration straightforward across the series.
