Product Description:

The MSK071E-0450-FN-M2-UG0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This motor acts as a high-precision actuator for automated machinery, supplying exact torque and velocity profiles to servo axes in packaging, printing, and assembly lines. Its design combines precise feedback with efficient heat removal to maintain repeatable positioning across continuous duty cycles in industrial environments. The motor is suited to indexing axes, feed systems, and transfer units that require stable motion during repeated starts, stops, and speed changes.

Cooling is handled by a closed-loop liquid cooling circuit that moves coolant through the stator jacket, allowing high continuous torque without depending on ambient airflow. Position data leaves the motor through a rotatable 240° connector, and the digital feedback uses the EnDat2.1 interface so the drive can read absolute position and diagnostics on a single line. The optical encoder provides 2048 signal periods, and internal interpolation supports smooth velocity regulation. Because it is a multiturn absolute encoder, it retains revolution counts after power loss and reduces the need for homing. The housing is sealed to IP65, which keeps dust and low-pressure water jets away from internal components.

Increased concentricity machining reduces rotor runout, and the shaft is supplied as a plain shaft, easing coupling alignment. That layout supports direct connection to common couplings and machine-side mounting hardware without adding special shaft features. Permitted ambient operation spans 0 to 40 °C, and insulation class 155 allows the windings to operate at elevated temperatures. The motor uses frame size 071 with length code E, giving it the mounting geometry associated with this housing size. The drive uses winding code 0450, which corresponds to the phase resistance and inductance expected by the inverter. The motor ships without a holding brake, so static position must be secured by external means.
