The Bosch Rexroth R911336917 (MSK050C-0600-NN-S1-UG1-NSNN) is an IndraDyn S synchronous servomotor designed for closed-loop control with a single-turn optical Hiperface encoder, providing 128 signal periods and accuracy of ±120 angular seconds. The motor features a plain, sealed shaft, natural convection cooling, a 240-degree rotatable power and feedback connector, and is engineered to operate with a continuous torque of 5.5 Nm (at 100 K), peak torque of 15 Nm, and a holding brake torque of 6 Nm. It supports a supply voltage of 7–12 VDC for the encoder, has a winding resistance of 1.7 Ω (at 20°C), winding inductivity of 11,100 mH, and is rated for maximum speeds up to 6000 RPM, with operation in ambient temperatures from 0 to 40°C and a sound pressure level below 75 dB.

Frequently Asked Questions

What does the MSK050C torque constant provide?

The 0.89 Nm/A torque constant defines torque output per ampere of current. It improves vector control efficiency and simplifies servo loop tuning.

How does the 24.8 A peak current help?

The 24.8 A peak current rating sets drive and cable sizing margins. It prevents tripping under load while avoiding unnecessary system oversizing.

Why is rotor inertia value technically significant?

Rotor inertia of 0.00033 kg·m² governs acceleration and resonance behavior. Balanced ratios ensure smooth motion transitions while avoiding system instabilities.

How does the motor’s inductance affect bandwidth?

The stator inductance moderates current ripple and switching effects. Higher values reduce harmonics but limit control loop responsiveness in high-dynamic applications.

What impact does winding resistance have on efficiency?

Low resistance minimizes copper losses and improves overall efficiency. However, reduced damping increases the risk of overshoot in fast-response servo systems.
