Product Description:

The MSK071E-0450-FN-S1-UG0-NNC1 is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Installed on packaging lines, pick-and-place gantries, or metal-cutting spindles, it delivers electronically controlled torque and speed so automation controllers can execute programmed motion profiles with repeatable accuracy. Size 071 hardware with length code E provides the torque needed for mid-frame axes, and winding code 0450 matches the electrical characteristics required by IndraDrive converters.

It dissipates heat through liquid cooling, letting the stator hold rated current even when mounted inside a sealed cabinet. The encoder connector is a 240° rotatable plug, so the cable exit can be aligned with surrounding hardware. Position feedback travels over the Hiperface bidirectional interface, which carries absolute position and electronic nameplate data on two conductors. Inside the feedback head, an encoder scale generates 128 signal periods per mechanical turn, and real-time interpolation in the drive yields sub-arc-minute resolution. The scanning element is optical, giving low jitter over the full operating speed range. Because the unit is supplied without a holding brake, loads must be secured externally when power is off.

The feedback device records a single mechanical revolution; the single-turn construction lowers memory needs compared with multi-turn models while still enabling immediate absolute startup. A rugged aluminum housing and shaft seal provide IP65 ingress protection, so coolant spray and airborne dust do not reach the internal laminations. Continuous duty is permitted at ambient temperatures of 0–40 °C, which helps prevent drive derating or premature insulation aging. Power leaves the motor through a plain shaft, reducing coupling runout and eliminating stress concentrations created by a key. Class 155 insulation withstands elevated winding temperatures and supports the thermal capacity of the liquid-cooled stator under cyclic loading.
