The R911321995 (MSK101D-0300-NN-S2-BG0-RNNN) is a synchronous servo motor from the MSK series, designed for use in automation systems where high positional accuracy and reliability are required. Equipped with a single-turn optical encoder (EnDat2.1, 2048 signal periods) providing ±20 arc seconds system accuracy, this motor supports precise position feedback. The unit features a 101-size frame with 'D' length, a plain output shaft for zero-backlash operation, and a B-side power connector. Cooling is achieved via natural convection. Rated for a continuous standstill current of 34.9 A and torque of 57.0 Nm at 100 K, the motor supports a maximum current of 137.7 A and torque of 160.0 Nm, with winding inductivity of 3,200 mH. The product incorporates a KTY84 temperature sensor and operates with an IP65 protection rating.

Frequently Asked Questions

How does increased concentricity in MSK101D-0300-NN-S2-BG0-RNNN servomotor improve performance?

The increased concentricity of MSK101D-0300-NN-S2-BG0-RNNN servomotor minimizes eccentric mass imbalance, reducing vibration and bearing stress. It supports smoother high-speed operation and longer bearing life.

In what applications is MSK101D-0300-NN-S2-BG0-RNNN servomotor especially used?

The MSK101D-0300-NN-S2-BG0-RNNN servomotor is widely used in CNC machining centers, robotic joints, and packaging lines where tight positional control and high torque are essential.

What is the maximum permissible radial or axial load for this motor?

The MSK101D-0300-NN-S2-BG0-RNNN servomotor defines permissible radial and axial forces per size to protect bearings. Exceeding those limits can shorten bearing life or cause mechanical failure

What is the inductance value of 3,200 mH effect in this motor?

The high winding inductance smooths current ripple and mitigates torque pulsations. It also affects the dynamic response and the needed drive tuning.

What advantages does the optical EnDat2.1 interface provide?

The optical EnDat2.1 offers high signal integrity with immunity to electromagnetic noise. It supports precise absolute position feedback using 2048 signal periods per revolution.
