The R911321778 (MSK040B-0450-NN-S1-UP0-NNNN) is an IndraDyn S synchronous servomotor with a frame size of 040 and length B, designed for industrial automation applications. It provides a maximum torque of 5.1 Nm and a maximum current of 6.0 A, with continuous values at standstill (100 K) of 1.9 Nm and 1.7 A. The motor uses natural convection for cooling and features a thermal time constant of 13 minutes. It incorporates an optical singleturn encoder with Hiperface interface, 128 signal periods, and a rotatable connector (240°). Additional specifications include a voltage constant of 77.8 V/1000 rpm, a winding resistance of 14.70 Ohms at 20℃, a winding inductivity of 64,700 mH, and a maximum speed of 6000 rpm. It operates at noise levels below 75 dB, has an IP65 rating, thermal insulation class 155, and is suitable for use in environments from 0 to 40℃. The shaft is equipped with a keyway and sealing ring in accordance with DIN 6885-1, with the motor connector on the A-side. This unit is supplied without a holding brake and is intended for installation and operation by trained personnel.

Frequently Asked Questions

Which cooling method does this motor support?

The motor relies on free air circulation for heat dissipation. The installer must ensure adequate spacing around the unit for airflow.

What is the benefit of having a rotatable encoder connector?

The connector allows flexible cable routing during installation. The technician can align it within 240 degrees to reduce strain on cables.

Why is optical encoder technology relevant in precise automation tasks?

The optical system provides accurate position feedback with minimal error. The result is smoother motion control in automated machinery.

How does singleturn encoder design impact performance?

The encoder can track one mechanical revolution without reset. The design simplifies control where multi-turn tracking is unnecessary.

What are the implications of a motor without a holding brake?

The shaft will not remain fixed when power is off. The application should include an external brake if holding is required.
