Product Description:

The MSK071D-0450-FN-S1-UG2-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It functions as a rotary actuator that converts commanded drive currents into precise torque for positioning tasks in automated machinery. By integrating feedback and an electrically released holding brake, the unit supports accurate axis control and secure stopping during power interruptions. This makes it suitable for packaging lines, pick-and-place modules, and other motion systems that require tightly controlled speed and torque during repeated operating cycles.

To manage thermal loads, the motor uses liquid cooling, and the housing has an IP65 protection rating, so coolant passages and seals help keep out dust and low-pressure water during operation. The motor requires FN cooling, which means the machine must provide the matching coolant circuit for proper heat removal. An electrically released brake provides 30 Nm of static torque, allowing the shaft to remain locked during vertical-axis standby without energizing the windings. The motor is rated for ambient temperatures from 0 to 40 °C, which supports operation near other heat-generating equipment when the cooling circuit is correctly maintained.

The integrated feedback package uses a Hiperface digital interface, and its optical scanning method generates 128 signal periods per revolution in a single-turn format for absolute position reporting within one mechanical turn. Class 155 insulation is used with the 0450 winding and supports continuous operation under the thermal conditions expected for this motor length. The motor also has a plain output shaft for low-backlash coupling and a 240-degree rotatable connector that helps with cable routing in compact installations. Its 071 frame size and D-length housing make it suitable for machines that need a compact servo motor with consistent positioning response and stable feedback performance.
