Dutch term or phrase: rotatiemoment
I found https://www.proz.com/kudoz/english_to_dutch/automotive_cars_... … where "rotatiemoment" is translated as "rotating torque". However, isn’t "torque" sufficient (as a translation of "rotatiemoment")?

I have also found it translated as "moment of rotation" in one EU source.

context:

"...waarbij de spoelen en het magneet systeem zo gemonteerd zijn dat door het sturen van een elektrische stroom er doorheen een rotatiemoment kan opgewekt worden op de XXX-as..."

turning moment
Explanation:
What they mean here, of course, is that a force is generated that, in the given configuration, can cause a shaft lying in the XXX axis to turn, i.e. causes or tends to cause angular displacement of the shaft with respect to that axis. Since this term occurs in a patent text, I would stick to the source as closely as possible and translate it as 'turning moment'.

An alternative term in Dutch is 'draaimoment', which GWIT, besides 'turning moment', also renders as 'moment of torque' or simply 'torque'. I would not use these alternatives in this context because 'torque' is usually, although certainly not exclusively, used in the context of engine or motor specifications in combination with power and rotational speed. In that context, the term 'koppel' is usually used in Dutch. 'Moment of torque', in my humble opinion, is rather tautologous too.

You will find a reasonably good explanation of the concepts of moments and torque in a series of presentations on the Khan Academy website (please see the ref. below). Even there, however, you will find that the terms 'moment' and 'torque' are sometimes used interchangeably.

Or preferably, upon further consideration and given the additional context: rotation moment (see discussion above). Both terms obviously mean the same thing.

Reference

Reference information:
In physics, a moment is a turning effect of a force. It is an expression involving the product of a distance and a physical quantity, and in this way it accounts for how the physical quantity is located or arranged. Moments are usually defined with respect to a fixed reference point; they deal with physical quantities as measured at some distance from that reference point. For example, the moment of force acting on an object, often called torque, is the product of the force and the distance from a reference point. In principle, any physical quantity can be multiplied by distance to produce a moment; commonly used quantities include forces, masses, and electric charge distributions.

https://en.wikipedia.org/wiki/Moment_(physics)

Krachtmoment, of simpelweg moment (zie bijvoorbeeld ook impulsmoment en traagheidsmoment), is in de mechanica en constructieleer een maat voor het rotatie-effect van een kracht (zie ook bij koppel).

Verschil koppel en moment:

Er is sprake van een koppel als er meerdere krachten op een voorwerp worden uitgeoefend, die op verschillende plaatsen op het voorwerp aangrijpen, zodat ze het voorwerp zouden kunnen laten draaien. De grootte van een koppel is gelijk aan de kracht maal de arm. De arm is de loodrechte afstand tot de krachtvectoren. Het verschil tussen een koppel en een moment is dat het krachtenspel van een koppel zodanig symmetrisch is dat er geen netto dwarskracht overblijft; indien het voorwerp vrij zou kunnen bewegen zou er alleen rotatie en geen translatie (verplaatsing) van het voorwerp plaatsvinden.

....rotatiemoment kan opgewekt worden op de XXX-as...

Zie onder

...het draaimoment dat op de as wordt uitgeoefend...

Volgens mij hebben ze het hier gewoon over 'torque'.

koppel = draaimoment = torque

draaimoment = rotatiemoment

Bij elektromotoren praat men ook van losbreek koppel en kipkoppel. Het losbreek koppel is het draaimoment dat op de as wordt uitgeoefend bij het inschakelen van de motor. Het kipkoppel is het hoogste draaimoment dat de elektromotor af geeft tijdens het opstarten. Het losbreek koppel ligt vaak rond de 80% van het nominale koppel en het kipkoppel ligt vaak rond de 200 tot 250% van het nominale draaimoment.
