Product Description:

The MSK071E-0450-FN-S1-UG2-NNNN servomotor is built by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As a closed-loop rotary actuator, it converts commanded current into precise torque for indexing tables, pick-and-place arms, and coordinated gantry axes in industrial automation. By delivering repeatable motion profiles, the unit maintains process accuracy and cycle time across multi-axis production lines. Its synchronous design suits applications that require fast response, steady torque delivery, and accurate position control during repeated start-stop cycles.

Cooling is handled by liquid cooling, which channels coolant through the stator jacket so continuous power can be produced without exceeding insulation limits. The housing carries an encoder connector that is rotatable through 240°, allowing cable exit to align with surrounding equipment while maintaining strain relief. Position feedback is transmitted over the Hiperface digital protocol, and the motor’s optical sensor head supplies 128 signal periods per revolution for fine interpolation in servo loops. This arrangement supports accurate commutation and stable closed-loop position control across the operating range. An electrically released brake provides 30 Nm of holding torque, keeping vertical loads in place when power is removed and releasing the shaft when energized. The winding code 0450 and length E identify the electromagnetic package, and the motor must be installed with the FN cooling circuit active.

The enclosure is sealed to IP65, so airborne dust and low-pressure water jets cannot enter the stator cavity or feedback compartment. Within the specified 0–40 °C ambient range, heat extracted by the coolant keeps internal temperatures below the limit for insulation class 155, protecting varnish and winding integrity. A plain shaft simplifies coupling to gearboxes or direct-drive elements by eliminating keyways that can introduce backlash. The smooth output end is well suited to clamp-style couplings and other connections where a keyed shaft is not required. The 071 frame and standard mechanical design provide consistent mounting dimensions across the series, which helps the motor fit common machine interfaces in this size.
