Commutator used in a sentence

Commutator in a sentence as a noun

Don't DC motors have a lot of commutator noise?

The spark plugs are fired by a rotating commutator switch in the distributor cap.

You can generate it anywhere you can rotate a commutator.

> better commuteWasn't a big issue for us at least as we have double decker commutator trains.

That the graphite is soft is why it works well but also why it wears out rather than the commutator, which will survive several sets of brushes.

That means instead of having a commutator to apply the voltage to the coils, a computer switches some FETs to apply the voltage.

An actual DC motor uses a commutator and brushes, which is a serious maintenance and safety issue.

Of course you don't need a "DC-DC converter" if your motor is AC, which every motor without a mechanical commutator is.

This implies that [A, B]|n> = 0 which generally contradicts the idea that A and B don't commute; certainly when the commutator is just a constant.

Wall-plugged motors use AC, in which case they have no high-frequency harmonics, or they are DC in which case the ultrasonic noise comes from the brushes scraping and arcing on the commutator.

We had to build a custom power tester using old motor brushes and an old commutator driven by a small motor in order to simulate ugly power supply scenarios.

Solving the cube in general requires exploiting this property by using what are called commutators, which are performing a move and then another move and then reversing the second move and reversing the first move.

If it were Abelian, then that would leave you in the place where you started — which is to say you reversed time — but the state will actually have changed where the first and second move manipulated the same pieces — which makes it non Abelian and breaks ‘time symmetry’So in this case, think of some physical operation that changes the state of the object somehow as being the same as a Rubik’s cube move, and assuming the operations have an inverse, that performing a commutator where you do one operation and then another and then invert the second and then the first, that leaves you in a new state, which would not be the case if it were time invariant.
