Product Description:
The MSK071E-0450-NN-M1-UG1-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S motor, it supplies controlled torque and speed to precision axes used in pick-and-place equipment, indexing tables, and coordinated gantry drives. When paired with an IndraDrive controller, it provides feedback-driven positioning so mechanical loads follow programmed motion profiles with high accuracy. Its servo response suits applications that require repeatable acceleration, smooth interpolation, and stable stopping behavior under changing loads.
Thermal management relies on natural convection, eliminating the need for forced-air accessories and letting the housing shed heat into the enclosure atmosphere under rated load. Position feedback comes from an optical encoder that communicates through the Hiperface interface, enabling absolute position transfer to the drive after power-on. Within the scanning head, the disk carries 128 signal periods, which balances resolution with update speed for rapid servo loops. The sensing system uses multiturn absolute feedback, so the drive knows rotor position across multiple revolutions without homing. To ease cable routing, the encoder connector is rotatable through 240°, allowing the plug orientation to be adjusted after the motor is fixed in place. Absolute feedback also helps reduce restart delays after brief power interruptions.
An electrically released holding brake provides 23 Nm of static torque, so vertically mounted axes can remain stationary during power loss. The motor uses a plain shaft, which allows direct coupling with clamped hubs or gear inputs without keyways and helps reduce concentricity errors. Frame size 071 matches the flange and stator diameter used in MSK mounting patterns, while winding code 0450 corresponds to the motor's electrical characteristics. This arrangement supports compact mechanical integration where couplings, gearheads, or belt pulleys must fit within limited machine space. The standard housing resists process dust and oil when installed in typical enclosure classes.
