Product Description:

The MSK071E-0300-NN-S3-UG0-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It supplies controlled torque and speed to machinery axes in packaging, printing, and handling cells. A standard mechanical layout and the 071 frame size permit direct mounting to gearboxes or belt drives, while the E-length housing provides additional active material for higher continuous power.

Heat from the windings leaves the stator by natural convection, so no external fan or liquid loop is required, which simplifies maintenance and keeps the enclosure compact. The sealed housing carries a protection rating of IP65, preventing dust ingress and withstanding water jets in factory washdown areas. A plain shaft couples directly to load elements, and position feedback travels over the Hiperface interface through a rotatable 240° connector that eases cable routing. The motor operates continuously at ambient temperatures of 0–40 °C without derating, provided air can circulate around the fins. Because it is supplied without a holding brake, external clamps or drive torque must secure vertical loads when power is removed.

The encoder uses capacitive scanning, which resists dust and vibration and maintains reliable signals. Its single-turn evaluation supplies absolute position data for one mechanical revolution, and the disk generates 16 signal periods so the drive can interpolate fine incremental angles for smooth velocity loops. This arrangement helps the drive maintain stable commutation and smooth low-speed control. Electrical behavior is set by winding code 0300, matching the motor with IndraDrive amplifiers that provide the required current and voltage. The motor uses 155 insulation class materials, allowing the stator to reach temperatures acceptable for Class F operation without premature aging.
