Commutation theory only appears 24 times on Google and so it makes me suspicious that it's not exactly the most appropriate translation...could "switch theory" be correct, it sounds odd to me, but it appears 500 times and in some cases it applied to this subject/
Thanks

Commutation Theory
Explanation:
As you see below, there are 17600 sites on Yahoo devoted to this topic. So I wouldn't worry too much about it not being a standard subject. Sounds like Google just isn't set up well for it.

It seems to me that if there are 17600 sites that even mention Commutation Theory, as there apparently are, you don\'t really have to worry about not being understood.

It is not clear to me why it should be necessary for the term to appear as \"Commutation Theory\" rather than \"Theory of Commutation\" or \"Principles of Commutation\" etc. There is nothing to worry about.

Explanation:
because I quote and unquote my questions in order to screen the results. I found nothing in my technical dictionaries (Collazo and Louis Robb), nor in Simon & Schuster. Hope this helps.

Explanation:
The context of most of those 24 Google hits IS academic, and DO concern Engineering course syllabi. This is not a question of statistics, it's a question of context. I could search "switch theory" and come up with all the companies wanting to sell me a switch. (BTW, I'm still looking for "batería + vibradores" in concrete and get all sorts of sex shops).

AC theory (alternating current theory?)


Explanation:
RAE:
conmutación: acción y efecto de conmutar.

conmutar: (1) cambiar en general una cosa por otra (2) Tratándose de penas o castigos impuestos, sustituirlos por otros menos graves (3) Sustituir obligaciones o trabajos compensándolos con otros más leves (4) Dar validez en un centro, carrera o país, a estudios aprobados en otro (5) comprar, vender o cambiar comercialmente unas cosas por otras.

conmutativo/a: (4) Dícese de la propiedad de ciertas operaciones cuyo resultado no varía cambiando el orden de sus términos o elementos (5) Dícese también de las operciones que tienen esta propiedad.

conmutatriz (Electr.) Aparato que sirve para convertir la corriente alterna en continua, o vice-versa

I have written \"DC Brushless Commutation Theory\" report (about 50-60 pages with a lot of drawings). It explains how to simulate trapezoidal (6-step) DC brushless (making difference between commutational interval and interval between commutations) and covers much of the above.

The \"DC\" refers to the supply voltage, not the motor design, and its use stems from historical marketing use, not fundamentals of engineering. Traditionally DC brush motors were used in many types of systems to avoid the complexity and cost of electronic commutation. But their use caused a whole family of problems, and when electronic commutation started to become feasible and cost-effective, marketing people wanted to sell the idea of having a \"drop-in\" replacement for the DC brush motors, but without the brushes.

The early electronic commutation schemes had simple \"six-step\" switching logic, so to minimize the torque ripple, the backEMF/torque waveforms are squarer than the sinusoidal waveforms of a classic AC synchronous motor. These motors are often said to be \"trapezoidally wound\" instead of \"sinusoidally wound\".

Now that more sophisticated commutation algorithms are available, which produce a good sinusoidal voltage from a DC bus, many brushless motors are sinusoidally wound to match. Unfortunately, there is no agreement on the terminology for this market -- some call them AC brushless, some call them DC brushless, but emphasize the sinusoidal windings.

I agree with jerryk and Robert here that it should remain \"Commutation theory\" - all I\'m doing is trying to shed a bit of light on it all.. and you may find the following few pages very interesting:

\"The aim of this invention, for which we have filed a provisional patent application, is to provide **linear commutation** more effectively and at lower cost than is currently possible with interpoles or by brush shift. The invention is in theory only, at this stage. Accordingly, we deal with the theory in some depth in this presentation. Our expectation is that our treatment will draw positive responses from engineers versed in **commutation** and in the electronics which is also involved.\"
