The R911315840 (MSK101D-0300-NN-S1-AP2-NNNN) is an MSK series synchronous servomotor engineered for integration with servo drive systems. This unit features a standard design housing and supports four electrical connection options located on the A-side. It operates with natural convection cooling and an IP65 environmental protection rating. The integrated optical singleturn encoder supports Hiperface interface with a resolution of 128 signal periods. The shaft is equipped with a keyway, and a 70 Nm electrically-released holding brake is included. Key specifications: 34.9 A continuous current at standstill, 57.0 Nm continuous torque, 137.7 A maximum current, 160.0 Nm maximum torque, and 3,200 mH winding inductivity. Operating temperature range is 0 to 40°C. Handling is restricted to qualified personnel.

Frequently Asked Questions

How does the peak current of 137.7 A relate to drive selection?

The drive must support at least the 137.7 A peak for short acceleration pulses without saturating. It also requires proper bus voltage and decoupling to handle those peaks.

What is the bearing life expectancy of this servomotor under proper loading?

The specified L₁₀h life for bearings is 30,000 hours when axial/radial loads remain within limits and lubrication is adequate. This ensures long-term reliability in continuous service.

In what applications would MSK101D-0300-NN-S1-AP2-NNNN servomotor be ideal?

The MSK101D-0300-NN-S1-AP2-NNNN servomotor suits demanding CNC axes, articulated robot joints, or precision packaging lines, where high torque density and accurate encoder feedback drive performance. Its built-in brake and stiff frame enhance safety and rigidity.

What role does the 3,200 mH winding inductivity play?

The high inductance smooths current ripple and reduces electrical noise, enhancing drive stability. It also moderates current spikes during acceleration or regeneration.

How does the natural convection cooling in MSK101D-0300-NN-S1-AP2-NNNN servomotor help performance?

The MSK101D-0300-NN-S1-AP2-NNNN servomotor’s natural convection cooling passively dissipates heat without fans, reducing vibration and maintenance. It ensures a stable thermal envelope up to defined temperature rise (e.g. 60 K on the housing) under continuous load.
