The R911339383 (MSK101D-0300-FN-S1-BG0-NNNN) is an IndraDyn S series synchronous servo motor featuring liquid cooling and a plain shaft design. A KTY84 thermal sensor, combined with an additional temperature model, supports temperature regulation. Position and speed are measured by an integrated single-turn optical encoder with Hiperface interface, offering 128 signal periods. The housing is IP65 rated and coated with epoxy polyamide resin for increased resistance to environmental factors. This motor has a 101 frame size, D length, no holding brake, and four pole pairs. Electrical characteristics include a continuous current at standstill (100 K) of 34.9 A, a continuous torque at standstill (100 K) of 57.0 Nm, maximum current of 137.7 A, and maximum torque of 160.0 Nm. Maximum speed reaches 4,600 rpm and operational altitude is up to 1000 m. Winding inductivity is 3,200 mH. The output shaft uses a sealing ring per DIN 3760 – design A. Power connection is on the B-side.

Frequently Asked Questions

How does the optical Hiperface singleturn encoder affect control latency or jitter?

The 128 signal periods optical Hiperface encoder offers high resolution feedback with minimal latency, but care must be taken in cable routing and shielded wiring to avoid signal jitter or cross-talk.

How susceptible is the motor to overheating faults and what recovery behavior is expected?

Liquid-cooled MSK motors may take over two hours to cool sufficiently after a thermal shutdown, so fault recovery should allow full cooldown before reapplying power.

What are the storage or transport precautions for this liquid-cooled motor?

Prior to transport or cold storage (below 0 °C), fully drain the coolant lines to avoid frost damage to the cooling passages.

How does winding inductance (3,200 mH) influence drive tuning or responsiveness?

The relatively high inductance smooths current ripple but also slows current rise time, so drive control loops must be tuned to balance responsiveness versus stability under dynamic loads.

Can the motor operate reliably under radial or axial shaft loads?

Yes, provided the radial and axial forces stay within the allowable limits specified in the “Bearing & Shaft Load” section of the project planning manual; exceeding them shortens bearing life.
