The Bosch Rexroth Indramat MSK071D-0300-FN-M1-UP0-NNNN servo motor delivers advanced motion control in the MSK IndraDyn S Synchronous Motors series, combining high-resolution feedback and robust industrial design. This brushless synchronous servomotor features a 4-pole-pair configuration and a multi-turn absolute optical encoder system for smooth, precise positioning. Designed for continuous operation, it withstands harsh environments with an IP65 degree of protection and natural convection cooling, further enhanced by optional forced-air or liquid cooling interfaces. The compact footprint and standardized D-length, size 071 frame enable integration in space-constrained systems while providing reliable performance. Robust construction and maintenance-free operation ensure long service life and minimal downtime.
Detailed electrical and mechanical specifications define the MSK071D-0300-FN-M1-UP0-NNNN’s capabilities. The winding code 0300 supports a continuous current at standstill (100 K) of 10.7 A and a continuous torque at standstill (100 K) of 20.0 Nm. Peak performance is achieved with a maximum current of 40.5 A and a maximum torque of 66.0 Nm. The winding inductivity of 10,700 mH contributes to low-cogging torque and refined speed control. A shaft with keyway output and without holding brake configuration ensure smooth power transfer, while the standard design and product type designation as an IndraDyn S Synchronous Servomotor simplify selection.
Operational features emphasize thermal stability and acoustic performance under load. The motor’s thermal time constant of 18 minutes allows predictable temperature rise during extended duty cycles. Maximum rotational speed reaches 3800 rpm, enabling high throughput in dynamic applications while maintaining torque integrity. An encoder interface utilizing the optical Hiperface protocol with 128 signal periods resolution and multiturn absolute capability delivers precise position feedback. The rotatable encoder connector, providing 240° flexibility, facilitates simple cable routing in compact machine assemblies. Sound pressure remains below ~75 dB(A) at rated speed, reducing noise impact in work environments.
System integration is streamlined through compatibility with Bosch Rexroth IndraDrive controllers and standard encoder interfaces for real-time feedback and advanced motion algorithms. The motor’s liquid cooling provision and robust IP65 enclosure suit a wide range of industrial applications, including packaging, assembly automation, and CNC machining. Flexible encoder connector orientation and standardized mounting dimensions accelerate installation and reduce engineering effort. The MSK071D-0300-FN-M1-UP0-NNNN is ideal for high-precision, high-duty-cycle systems demanding consistent torque delivery and long-term reliability.
