The Bosch Rexroth synchronous servomotor R911372256 (MSK071C-0450-NN-M1-UP0-NSNN) is designed for precision applications demanding high torque density and dynamic performance. It integrates a multiturn absolute Hiperface optical encoder with ±80 angular seconds accuracy and an encoder resolution of 128 signal periods over 4,096 mechanical rotations. The motor features a C-length, 071 frame size, a shaft with keyway, and a winding code of 0450. Electrical specifications include a continuous standstill current of 10.4 A, a continuous standstill torque of 14.0 Nm, a maximum current of 40.1 A, and a peak torque of 44.0 Nm. The shaft uses radial shaft sealing rings compliant with DIN 3760. It supports two rotatable connectors (power and encoder, 240°). Cooling is achieved through natural convection and heat conduction. The design supports both standard and explosion protection per DIN EN 60079. The motor is certified to IP65 for dust and water-jet resistance and is rated for operation at 0–40°C, up to 95% humidity, and installation altitudes up to 1000 m above sea level.

Frequently Asked Questions

Why is the 6,700 mH inductivity with winding code “0450” advantageous for current control behavior in MSK071C-0450-NN-M1-UP0-NSNN?

The inductance establishes a predictable electrical time constant for smoothing ripple and aiding stable current-loop tuning under dynamic load steps. It is tuned for responsive torque build-up to support aggressive acceleration without drive instability.

What continuous/peak ratings define servo sizing for MSK071C-0450-NN-M1-UP0-NSNN, and how should drives be selected?

It delivers 14.0 Nm at 10.4 A continuously, while its peak value reaches 44.0 Nm at 40.1 A for short-term demands. Its drive adequate continuous current plus transient headroom honors duty-cycle and thermal limits.

How do natural-convection cooling and frame heat conduction affect mounting and thermal margins for MSK071C-0450-NN-M1-UP0-NSNN?

Its self-cooling requires unobstructed vertical airflow and good contact to the machine frame to conduct heat away. Its spacing guidance for nominal data are maintained up to 40 °C ambient without forced ventilation.

What does the IP65 rating imply for washdown or dusty environments and connector selection on this MSK071C variant?

The IP65 indicates dust-tight construction and resistance to low-pressure water jets but not immersion. Its seal integrity and cable interfaces are critical.

What cabling conventions (separate power/feedback, 240° rotatable encoder plug) help MSK071C-0450-NN-M1-UP0-NSNN in tight machine envelopes?

The IndraDyn S motors use standardized separate power and encoder connectors; the power connector integrates a temperature sensor lead. Its ~240° rotatable encoder connector optimizes cable exit for easing routing and reducing bend-stress in compact panels.

Internal Product Review

The Bosch Rexroth Indramat’s MSK071C-0450-NN-M1-UP0-NSNN servomotor relies on a Hiperface multiturn optical encoder for feedback. It is designed with natural-convection cooling and it comes in an IP65 sealed housing. This motor provides 14 Nm/10.4 A continuous and 44 Nm/40.1 A peak to enable cyclic duty to fit into machine tools, packaging, printing lines and industrial robotics.
