Product Description:

The MSK071E-0300-NN-M2-UG0-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It uses frame size 071 with the elongated E length and a plain shaft for direct coupling to driven mechanics. The rotor and stator set have increased concentricity to reduce radial runout in high-precision axes. As a closed-loop torque and position actuator, the unit provides controlled rotary motion for packaging stations, pick-and-place gantries, and indexing tables. It is intended for servo axes that need accurate repeatability during frequent start-stop cycles.

Heat dissipation is handled solely by natural convection, so installation must allow unobstructed airflow around the housing. The cast-aluminum enclosure carries an IP65 ingress rating and can run continuously in ambient temperatures from 0 to 40 °C without derating. A rotatable 240° connector lets the feedback cable exit in the preferred direction, and the encoder communicates over the EnDat 2.1 serial interface. The copper windings use code 0300, and their thermal capacity corresponds to insulation class 155 for F-class temperature limits. This arrangement supports cyclic-duty operation with compatible IndraDrive controllers during frequent speed and position changes.

Position data are delivered at a granularity of 2048 signal periods per mechanical revolution by an optical scanning system. Absolute multiturn counting is available for up to 4096 revolutions through the encoder’s multiturn absolute design, which removes the need for homing after power loss. The motor is supplied without a holding brake, so vertical axes must rely on external clamping or drive torque for standstill security. The encoder arrangement supports consistent position tracking during restart and normal motion.
