Product Description:

The MSK071E-0300-FN-S1-UG2-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a compact drive element, it converts electrical energy into controlled torque and speed for positioning axes, packaging stations, and other motion tasks in automated machinery. The motor has size 071 and length code E, and its FN suffix indicates that an external coolant supply is required for continuous operation. This arrangement suits installations where thermal load is high and a closed machine layout limits the usefulness of free air circulation.

This unit employs liquid cooling, so heat is removed at the stator jacket and higher continuous power can be delivered in restricted enclosures. A factory-mounted holding brake rated at 30 Nm is electrically released, allowing mechanical load retention when power is off and rapid restart when the brake coil is energized. The housing carries a protection level of IP65, which keeps out dust and resists low-pressure water jets during normal machine use. Feedback signals are transferred via a Hiperface interface, and the single-turn optical encoder resolves rotor position over 128 signal periods, supporting precise commutation and stable velocity regulation at the drive.

The encoder connector is rotatable through 240°, which helps cable routing where space around the motor is limited. Its sensing principle is optical, so position data are not affected by magnetic drift over time. Mechanical coupling is through a plain shaft that suits clamp or collet hubs without keyways. The motor operates within an ambient range of 0 to 40 °C, and its insulation system uses class 155 materials for continuous thermal endurance. The 0300 winding is matched to compatible drive amplifiers for the electrical characteristics used with this motor size.
