The Bosch Rexroth synchronous servo motor R911322173 (MSK071D-0450-NN-S1-UP2-NNNN) is a component of the IndraDrive system, designed for applications such as machine tools and packaging equipment. It utilizes natural convection for cooling and integrates a KTY84 thermal sensor within the stator for overload protection. The motor features a four pole pair configuration, a shaft with DIN 6885-1 keyway, and delivers a maximum speed of 6,000 rpm with a peak torque of 66.0 Nm. The single-turn optical encoder provides 128 signal periods with ±80 angular second accuracy and supports a Hiperface interface. The holding brake is electrically released with a holding torque of 30 Nm. The continuous torque at standstill (100 K) is 20.0 Nm with a continuous current of 17.6 A. The motor has a winding code of 0450, maximum current of 69.3 A, inductivity of 3,200 mH, and a moment of inertia of 0.00255 kgm². The housing is finished in black RAL9005 epoxy resin.

Frequently Asked Questions

How does the MSK071D-0450-NN-S1-UP2-NNNN improve mechanical security in high-vibration, torque-transmitting assemblies?

It features a shaft with keyway for positive mechanical coupling. This prevents slippage and ensures torque alignment in gear-driven or belt-tensioned systems under load.

Can this motor maintain locked positioning during safety stops or system power-downs?

It integrates a 30 Nm electrically released holding brake. This secures the shaft at standstill, eliminating the need for external brake assemblies in vertical or load-suspended axes.

How does the MSK071D-0450-NN-S1-UP2-NNNN ensure reliable thermal behavior in enclosed machine frames?

It uses natural convection cooling to manage temperature. This supports continuous operation without fans, reducing maintenance in sealed or space-constrained machine designs.

What feedback architecture supports precision in closed-loop control on this motor?

It includes a singleturn optical encoder with 128 signal periods using the Hiperface interface. This ensures high-resolution position data for accurate servo loop stability.

How does the MSK071D-0450-NN-S1-UP2-NNNN maintain torque consistency during current disturbances?

It uses a 3,200 mH winding inductivity to filter current ripple. This stabilizes torque output and improves motion smoothness in systems with high controller gain.
