Product Description:
The MSK071E-0300-FN-S2-UP0-RNNN servo motor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S synchronous servo motor intended for positioning and speed-controlled axes in automated machinery. The motor converts drive current from a Rexroth inverter into precise mechanical torque and supports repeatable motion in automated systems.
This E-length, size-071 frame unit relies on liquid cooling to remove losses directly at the stator housing, so continuous torque can be sustained without external airflow. Its enclosure carries an IP65 rating, which blocks dust ingress and low-pressure water jets during washdown cycles. Position feedback is provided through an EnDat 2.1 optical encoder that outputs 2048 signal periods, allowing the drive controller to interpolate high-resolution rotor angle data. The feedback head is mounted to a rotatable 240° connector for flexible cable routing, and the single-turn format keeps the arrangement compact. Inside the stator, winding code 0300 identifies the electrical resistance and inductance characteristics used with standard IndraDrive power stages. The motor uses a shaft with a keyway, and the compact 071 frame width fits into machines where axial space is limited.
The rotor and stator are ground for increased concentricity, which reduces radial runout when the motor is used with precision couplings. Thermal insulation class 155 allows the windings to reach higher temperatures before degradation and supports the liquid-cooled design. Operation is specified for ambient temperatures from 0 to 40 °C, so the motor can run within typical plant conditions without derating. The servo motor is supplied without a holding brake, making it suitable for axes that use an external mechanical clamp or another method of load retention at standstill.
