Product Description:
The MSK071E-0450-FN-S2-UG0-RNNN belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. As an IndraDyn S synchronous servo motor, it converts drive current from a designated controller into precise rotary motion for positioning or cyclic-duty tasks in automated machinery. Its frame size 071 and length code E place it in the medium-torque segment of the series, making it suitable for packaging lines, pick-and-place gantries, and similar systems that need accurate speed control.
Thermal management is handled by liquid cooling, allowing continuous operation at rated load without external fans. The housing has an IP65 rating, so dust and low-pressure water jets cannot reach internal windings. Position feedback is supplied through the EnDat2.1 digital interface, giving error-checked data to the drive controller. Inside the encoder, an optical scanning head provides 2048 signal periods per revolution, and this high native resolution translates into fine incremental counts after interpolation. The sensing principle is optical, which supports stable accuracy over temperature and time. Because the encoder is a single-turn model, it reports absolute position within one mechanical turn, while multi-turn tracking must be handled at the controller level. A plain shaft supports backlash-free coupling to gearboxes or load hubs, and the stator design emphasizes increased concentricity to minimize radial runout.
For flexible cable routing, the feedback connector is rotatable through 240°, so wiring can exit in several directions without strain loops. The motor is specified for ambient temperatures from 0 to 40 °C, matching typical enclosure conditions in production halls. Insulation class 155 supports winding temperatures up to 155 °C, giving margin against thermal spikes. No holding brake is fitted, so the axis must rely on drive torque or a mechanical lock when power is removed. The winding code 0450 indicates copper fill and resistance values matched to IndraDrive amplifiers, and the increased concentricity design works with the plain shaft to reduce vibration in applications that need smooth continuous rotation.
