The R911317573 (MSK071D-0450-FN-M2-UG0-RNNN) is an IP65/IP55-rated synchronous servomotor designed for environments requiring high resistance to particles and water. It delivers a maximum torque of 66 Nm and operates with a peak current of 69.3 A. The motor features liquid cooling and an EnDat2.1 optical multiturn absolute encoder with 2048 signal periods for precise position feedback. The design includes a plain shaft, rotatable 240-degree electrical connection, and black varnish coating less than 40 μm thick, providing resistance to seawater, sewage, grease, and acids. This flange-mountable unit supports installation up to 1000 meters altitude within an operating range of -20 °C to +80 °C and has a noise level of 75 dB.

Why is a rotatable encoder connector important during installation?

The rotatable connector simplifies cable routing in tight spaces. The flexibility reduces stress on cables and lowers risk of connection failure.

How does multiturn absolute encoder feedback improve machine accuracy?

The multiturn absolute encoder provides exact position data even after power loss. The precision ensures accurate restart and reduces need for homing cycles.

What benefits does optical encoder technology bring in this servomotor?

The optical encoder delivers high resolution position data for precise motion control. The accuracy improves repeatability and ensures smooth performance.

How does the absence of a holding brake affect system design?

The motor requires external mechanical holding if static load must be secured. The omission reduces overall weight and simplifies maintenance.

What role does winding inductivity play in motor performance?

The winding inductivity impacts the current response to voltage changes. The value influences torque ripple and affects drive tuning precision.
