The Bosch Rexroth Indramat MSK071C-0300-FN-M2-UG2-RNNN is a high-performance servo motor belonging to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S Synchronous Servomotor, this unit features liquid cooling and delivers a continuous torque at standstill of 14.0 Nm at 100 K. With a maximum torque of 44.0 Nm and a rated speed code of 0300, it is designed for demanding precision motion control tasks in automated production systems. The unit’s primary function is to provide reliable, high-precision rotary motion for industrial robotics, packaging machines, and CNC equipment.
Incorporating advanced optical encoder technology, the motor supports a multiturn absolute encoder with an EnDat2.1 interface, offering an encoder resolution of 2048 signal periods. The rotatable encoder connector (240°) simplifies installation in confined spaces and maximizes flexibility. Constructed with a plain shaft and an increased concentricity design, the MSK071C-0300-FN-M2-UG2-RNNN accommodates precise alignment and minimal mechanical runout. Electrical characteristics include a winding inductivity of 10,900 mH, a continuous current at standstill of 8.5 A (100 K), and a maximum current of 32.9 A.
This servomotor is equipped with a robust electrically-released holding brake providing 30 Nm of torque, ensuring safe and stable load holding when de-energized. The requirement for the FN liquid cooling variant enhances thermal management under continuous operation, improving efficiency and preventing overheating. Its plain shaft design and increased concentricity contribute to enhanced durability and reduced maintenance needs. Compliant with Bosch Rexroth Indramat’s rigorous quality standards, this motor offers precise, repeatable performance and long service life. Ideal for industrial applications, it delivers superior dynamic response and energy efficiency, reducing cycle times and operational costs.
