The Bosch Rexroth MPN R911339990 (MSK040B-0450-NN-M3-UG1-NNNN) is an IndraDyn S series synchronous servomotor with a size 040, length B configuration. Designed for precise motion control, it features a low inertia rotor suitable for dynamic applications requiring rapid acceleration or deceleration. The unit supports natural convection cooling and is housed in an IP65-rated enclosure. It includes a plain shaft, an electrically-released holding brake rated at 4 Nm, and utilizes high-quality permanent magnets. The stator winding code is 0450, with a continuous standstill current of 1.7 A and a continuous torque of 1.9 Nm at 100 K temperature rise. Maximum torque output is 5.1 Nm and maximum current is 6.0 A. The integrated Hiperface multiturn absolute capacitive encoder provides 16 signal periods and a rotatable connector (240°) for accurate position and speed feedback. The insulation class is 155, and the servo motor weighs 2.8 kg.

Frequently Asked Questions

What advantage does the capacitive encoder architecture offer in precision servo feedback loops?

Its non-contact sensing resists vibration and dust interference, maintaining exact position data across millions of revolutions without signal degradation.

How does the Bosch Rexroth Indramat MSK040B-0450-NN-M3-UG1-NNNN sustain torque linearity under variable acceleration profiles?

The Hiperface multiturn feedback constantly updates position with 16 signal periods, synchronizing current control for uniform torque delivery up to 5.1 Nm.

Under what environmental constraints does natural convection deliver optimal thermal balance?

It performs best in clean, well-ventilated enclosures where ambient heat dispersion keeps winding temperatures within rated limits during continuous 1.9 Nm output.

By what mechanism does the 4 Nm holding brake contribute to precision in vertically oriented assemblies?

The brake engages instantly upon de-energization, preventing mechanical drift and ensuring static positioning accuracy during system idle or shutdown.

Which preventive care practices ensure the Bosch Rexroth Indramat MSK040B-0450-NN-M3-UG1-NNNN maintains stable encoder alignment over years of service?

Inspecting connector rotation friction, securing cable strain relief, and cleaning the encoder interface help preserve accurate multiturn calibration and signal reliability.
